This kind of applies. I run a 3" TR&D on my turbo R. Obviously it will be different for your atmospheric car, but if the quality and fitment are the same as my system, you should be very happy. The only gripe I have with the system is that it's stainless, with mild flanges and mild welds, I would like to see stainless flanges and stainless alloy rod with nice tig welds, but that would bring the price up quite a bit. And I am constantly complimented on the sound.
