Hi all,

This is something I just came across on youtube! http://www.youtube.com/watch?v=im8NUhUfzYQ&feature=channel_video_title
This is the first I've heard of Stainless Works plans to make an exhuast system for the DeLorean!! I haven't seen it posted on the forum either.

Hope they make something thats sounds awesome!!!

This is the company who is making Josh's Spec 1 Exhaust systems. They are currently for sale through DeLorean Performance Industries. Contact Josh Bengston.

------Edit------
After watching the video, it looks like Josh is designing a new system. He talks about a "crossover pipe" like in the stock exhaust.

I just came across the exhaust system on youtube, not really crazy about the sound! http://www.youtube.com/watch?v=tcGP_ohMIKU

I really love the sound of this exhaust system: http://www.youtube.com/watch?v=OrOBCZWM8Zc Can anyone start making a kit like this??

The first video happens to be my car and it sounds better when its moving than it does just sitting. The video was taken with a cell phone and it really doesn't do the system justice.

The systems quality is also excellent, it looks great ceramic coated and you can really feel the difference in horse power once its installed. Much better than stock.

The muffler and heat shield are integrated and much smaller than OEM which provides plenty of room to work on idler bearings, change belts and the like. It uses the OEM mounting points, comes with all the hardware you will need to install and it can be done including removing your old system in about one day.

I also know that DPI will stand behind its products.

Oops, sorry about that, not meaning to bash it. Can you post a better video of it idling and driving?

Thank you! :wink:

This is our private label system we have been selling for a while. Only system on the market with a life time warranty against broken welds, rust or component failure. It is only available from Delorean Performance Industries. Stainless works refers all inquiries directly to us.

We just finished our new cat back system. We all now have stainless factory style manifolds to replace the cast iron units. The new cross over system and cat back system will be available shortly and is the same manifold/cross over configuration on our SPEC III turbocharger set up. Big thanks to Stainless Works for dropping everything to take care of us once again.

No need to apoligise, I we all have our own opinions, mine is biased by the fact it I paid good cash for the DPI Spec I.

One thing I will say for sure is that we will never get a throaty V8 sound out of a PRV.

I wish I had the equipment to make a better video. Josh should have his film crew put something together whlie the car is moving from inside or outside the car.

Here is a third unrelated party video as I happened to drive by one afternoon...
I show up at the 14:30 mark of this video. Unfortunately the guy talks over my exhaust a bit but it still sounds pretty good.

I like Josh's work, but haven't seen a car with his stuff installed yet. It's really hard to get a good, honest audio clip from a video/computer. Hoping to hear his stuff in person in the near future.


Yep, that's my car posted above before I installed cams, so the note is a bit more aggressive now.


http://www.youtube.com/watch?v=2Ju1ueq3su4




I knew I'd never get a true V-8 sound out of the PRV, but I was hoping to get something like the 3.1L Chevy Cavalier Z24 sound from the 1989-1992 years. I think I got pretty close.

The vidoe of your car really does sound good, but I agree it most likely sounds even better in real life.

Josh is only 6 hours hours away, take a drive go for a visit, I'm 21 hours away and I've been there twice. Or even better invite him out for a tech session, or do what we did and see if he will come to you pay him hourly rate to work at your place!

As for his work, I am one of the senior members in the Delorean community and remember driving a Delorean that was "Tuned" by the factory, and when Josh took my car and added the Spec I then performed a tune up, I can say it has never run better. His customer service is top drawer and he charges a fair price. He generally goes above and beyond.

I'm not saying anyone else's work is bad, but Josh's work is outstanding and the workmanship on his Spec I exhaust is first class and the warranty is forever.

I keep forgetting to mention the best part about owning a Delorean now as opposed to 10, 20 or 25 years ago....

Options so many options... I promise you that 25 years ago it was very difficult to get parts, any part.

Now we have people like John Hervey, Josh at DPI and even some others, this is why we are able to discuss the merits of so many different exhaust systems.

I also can't forget to mention DMCH and all of their affiliates, without them many of our parts might still be locked up by Consolidated and still very difficult to get.

Love the sound of the 2nd one as well. From what I know, it's a Flowmaster 80 series muffler. Same you'd find in a 3rd gen F-Body car.

I've been told though that there is severe highway drone with that setup.

I own 2 Trans Ams as well, one has a Edelbrock cat-back, the other FLowmaster cat-back, and the sound resembles my Trans Am, a little off of course cause different engines, but close enough!!

What do you mean by severe highway drone?

Untrue. I was actually surprised at how quiet it is inside the car after it gets above 1500 RPM. It's only lout at low RPM & at highways speeds is only slightly louder than stock.

To get back on topic... the Spec I exhaust is louder at any speed than stock. However, it isn't as loud as a Stage II set up.

The particular Stage II I've had the pleasure of driving was built in 2008. The 2008 Stage II has a very distinct drone at highway speeds which is much louder than stock even when the car has been sound proofed.

That's really good to know then! Grady was the one that told me to stay away from this solution.

I'd love to hear it in person.

I received the Spec 1 exhaust kit yesterday and it looks beautiful, thanks Josh B!
I spent a majority of the time cleaning the threads in the cylinder heads with a tap so that I could hand screw in the studs for the headers. If not for that I would have had the exhaust installed quickly yesterday. Today I will finish tightening everything up and put the muffler on. I will share pics and videos with all of you soon if you are interested.

Thanks again Josh B at Delorean Industries! Great High Quality Kit!

Here is a video of the Spec 1 exhaust with start up and idle..

http://youtu.be/62F3i0i_2ek


Here is a video that compares the Spec 1 exhaust to stock and UK exhaust. Unfortunately, a bolt backed out of the heat shield and you will hear the shield rattling during the video. The problem has since been fixed with stainless bolts and lock washers.

I had the same rattle too with my Spec 1. It happened about a thousand miles after installation. In my case, one bolt backed all the way out and was missing while two others were loose. So I got a replacement SS bolt and lock washers at the hardware store and it's been fine ever since.

I was suprised that the bolts appeared to be zinc plated instead of stainless steel and that they didn't have lock washers...(one bolt did back all the way out/the rest loose like yours) oh well, an easy fix and something to correct in the future...

I had the same problem. Also fixed with a stainless bolt but instead of a washer I just used a little blue loctite.

I thought this issue was because I didn't tighten the bolts enough (I used the lock washers as extra security "just in case"). Looks like it was a good call I used those washers then if this is happening to others!

If that's the only issue I have it it, then I'm still pretty happy. Everything else has been fantastic with it.

Josh installed mine and it didn't come loose for about 1200 miles (I drove my car home from Ohio.

I could tell the real problem was with the holes in the heat shield, expansion and contraction of the shield didn't allow enough movement around the bolt and caused it to come loose and fall out.

I elongated the holes with a drill and then put everything back together with a bit of locktite.

I currently do not have a starter heat shield. What are all of you using that will fit with the headers? It was pointed out to me and tested at the recent DCO event that the body of the starter stays rather hot when the headers are cool to the touch...I'd like to make sure my starter life isn't shortened...

You can run the stainless one we sell but it really isn't required. No premature failures. Plus now that the original starters are no longer available you should pull yours out and run a premier set up anyways saving the paris unit for a rainy day.

Hey Josh, can you post the wiring modification for the Eagle starter? I don't think this has been posted since the forum has been back up.

Guys, starters are available all over eBay UK. For example:

http://cgi.ebay.co.uk/Starter-Motor-Renault-V6-2-8-V6-06-84-10-91-/220514210438

These units are actually more powerful than the original, and are shorter too, allowing the use of the GTA oil cooler if you so wish.

Hey Josh, can you post the wiring modification for the Eagle starter? I don't think this has been posted since the forum has been back up.

Eagle starters only have one terminal instead of two like on a Delorean set up. Your Ignition bypass (blue and yellow tracer) and white with red tracer going to the solenoid. We have a little adapter harness that plugs into the factory harness we sell with the starter that runs both to the same terminal.

On every car through the door we always recommend upgrading to the late 83 style harness set up. This is something we do on all cars we install a spec I system on regardless. It includes a custom extra long 3 wire alternator to starter jumper that routes safely around the oil filter, jumper from hot lead jump point on the fire wall to coil compartment point and the starter harness modification harness.

Another note on the SPEC I system. We have had isolated incidents were the muffler heat shield welded mounting brackets have torn off the muffler. After extensive field testing and helpful input from owners we have redesigned these four mounting points on the next set of systems. Failures have been isolated to only 4 systems at this point out of over 100 currently on cars.

If a system fails we no longer repair the issue during the warranty process and simply replace the complete muffler with the upgraded unit. Even though this has been isolated to only a few issues with one being owner error I felt the need to amend the design.


Heat shield hardware. DO NOT use stainless. Anything you can pick up at a hardware store is a sub par Chinese bolt and will sheer off. We use zinc plated hardware for a reason so that this doesn't happen.

We ship the systems and do not tighten the hardware. The four mounting bolts must be checked during installation. We currently do not offer a PDF install guide for the system but will shortly noting this.

Glad to see positive reviews on this kit we are currently offering. We are always working to better our products and are never satisfied for a QC point of view here. Keep the comments, concerns and suggestions coming. This simply helps us to bring a better product to you.

One more thing. We offer in house ceramic coating that many owners have taken advantage of. Our indefinite partnership with Stainless Works as our fabricator for at this point over 300 individual components has one flaw. The exhaust system warranty does not cover the cost of ceramic coating a replacement warranty component. This is covered by us personally as guaranteed with the purchase of one of our systems in addition to the manufactures warranty.

What causes the stainless steel bolts to sheer off? I just checked mine and they are still ok and tight...

Also, what year/make/models of eagle starters can we use?

Thanks!
