I have dual cats & Magnaflow mufflers on my car. The headers on each side do a 180* and come straight back. The Magnaflows are 20" x 8" x ~4" and are offsets. 2.25" pipes. The orientation is great and it puts the tips in just the right place. The mufflers sit 'on edge'.
They are just too damned loud under load. At idle they are fine but they are just plain beefy and noisy for my taste. I realize quieter ones won't flow quite as well but I'm ok with that. I'm therefore looking for recommendations on brand or models that are essentially of the same dimension but quiet. From the picture you can see how they would have to fit.
Any suggestions? Thanks.
