Our MAD exhaust is a great option. It will unleash a ton of volume but if your after pops and bangs a flash will be needed.

+1 for MAD

Very balanced sound, with a deep midrange and a clean HIGH rpm tone.
its aggressive (especially with the valves open) but not obnoxious to still be a perfect daily driver.

I vote Dinan, I looked at a bunch of different systems and I wouldn’t trade this for anything. It gets loud with the valves open, highway diving is perfectly comfortable, it’s much cheaper than AWE and MPE and the 4” tips set it off.

I would start with a catted DP - unless you are after the looks of an aftermarket exhaust (quad tips as an example) - with the DP you will pick up an impressive amount of sound and tone and maybe get a little boost in performance

You need to remember that aftermarket exhausts on these cars are really only for sound and appearance. The stock set is already dual straigt piped from the DP to the muffler - which is why you are not seeing any real power gains when you go aftermarket.

a catted downpipe is an excellent starting point for more sound and power.
