The borlas xr1's sound good on my ltd with bullets in front of them, dual 3" setup. It has maxflows after the axle to really quiet it down. Edit: should mention I run the same mph thru the 6 mufflers as I do with open exhaust.

Kooks 3" True Duals here....for sound and quality, they can't be beat IMO. Awesome SS mandrels throughout and it looks amazing. They are a bit more pricey, but you pay for what you get and it's definitely worth it in my opinion. Call Bob at Brute Speed and get your pricing on it...they have come down a bit over the last couple of months I've heard.

The phb Relocation bracket/bar is all that's truly needed. Don't bother with the recommended ds loop. That hangs too low, I wish I'd of gotten the mwc loop. it'll be swapped out for one eventually. My kooks duals fit great. The only issues I have are the drivers tip being slightly crooked (seems to be inherent with this cat back) but its settled in quite a bit from the initial install and is almost perfectly level. I just notice it because its my car. Aside from that my only other issue is a very slight rattle when I start the car. It doesn't do it under any other circumstance but that I can live with for now.

Magna flow is alot better than most people think, ysi/403/t56/9" car I did made 886 through the magnaflow and 867 with the cutout open. Does it everytime on the dyno. Makes more power thru the exhaust, this car also has kooks headers

If you can find the right exhaust guy have some duals made, the kooks setup is really nice but my budget would never have it,i like my tsp duals, there a lil loud but sound great,i plan to run them back to a cme and get some magnaflows to tame it down a bit, the xr1s are nice but the borla s or whatever there called sound much better to me,its whatever you wanna deal with,can you deal with driving around in nascar mode 24/7,the very best setup imo with a catback is a magnaflow w/cutout,you have the best of both worlds
