Which exhaust kit should I get?

[PlutonimicX]

Just wondering Josh, is the a price difference now if purchasing one of the discontinued setup?

It is a rare occasion. We have all eight configurations of this system in shop as we speak. My audio friends will be making a compilation of all systems. The options are:

SPEC I Manual trans with cats
SPEC I Manual trans without cats (discontinued)
SPEC I Manual trans cat back
SPEC I Manual trans without cats and cams (partially discontinued)
SPEC I auto trans with cats
SPEC I auto trans without cats (discontinued)
SPEC I auto trans without cats and cams (partially discontinued)
SPEC I auto trans cat back

do you have a pic of the "cat back" options?

Forgive my ignorance but how does the transmission affect the design of an exhaust?

Not an ignorant question at all Nick. The transmission of power through the five speed/auto, shift points etc directly relates to how the exhaust sounds. All comes down to load at different rpms and throttle. For example: Test pipes on a manual sounds great and is unbearable on an auto. The exhaust is exactly the same minus with or without cats and or cat back only. The variable is the configuration it is attached to.

Hi Josh,

Do you mind describing "unbearable?" My county does not require emissions so I wasn't planning on using the cats. Plus I wanted the extra horsepower. My car is an auto, but I plan on swapping to a manual when time/money allows.

Thanks!

fyi...I agonized over this decision also. I narrowed it down to DPI and UK. Cost no object, I liked the sound of DPI much better. (some of the DMA members had them on their cars at the '14 dma event, so I could hear them.)

But the fact that the DPI was much less expensive that the UK, made my decision easy. Plus I think it weighs about 20lbs less (not sure of that.)

You'll be happy with either, but personally, I really like the DPI. I drive my car fairly frequently, and it is loud enough to sound good but not too loud to rattle my teeth.
