Why don't you get whatever catback you think sounds best and use an electric cutout. Best of both worlds; get the sound you want for cruising and open exhaust when you want to race.

That kooks true dual is very expensive by the time u buy the stuff from BMR and the exhaust system I was thinking the borla xr1 what do you guys think

Any straight through muffler, no baffles at all. Id go with something quiet and do a cutout as well. I run 9x14 full size magnaflow straight through and a cutout. Its quiet as stock with the cutout closed and plenty loud open.

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.

I agree with the cut out. I run a flowmaster 40 series. It sounds awesome. Doesn't flow worth a crap though so I use the cutout when im getting serious.

4" catback you need the pipe size to flow the air.

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.

How's the fit on the kooks true duals is thier any issues with rubbing anywhere is all you need is the pan hard bar relocation bracket

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.

Where's the best deal to purchase that exhaust from kooks them selves don't have any in stock and 3 to 4 week waiting period

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

Mufflex 4" would do it as well.

I like my stock slp dual dual, quiet and has a great tone without the rasp.

So are you saying that this cat back that he has for sale works real well i didn't mean to ignore it was just checking out all options

I have AHR L/T's with cats back to a Magnaflow catback with 12 inch Magnaflow straight through on the rear. No more rasp.

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
