So I've got my new motor running but the car is just too damn loud now. Big cube motor with LT headers, 2.5" mandrel bent exhaust all the way out to the back bumper (tailpipes going under the rearend) Its got a x-pipe from www.pypes.com and some sweet thunders on it. Its just way too loud... for me and for the cops. Long trips are gonna require ear plugs and I'm not joking. So now I'm wondering what to do. Should I ditch the sweet thunders and just do 2.5" over the rear axle and then do traditional mufflers or what? If so, what mufflers make great power but aren't too ignorant loud. Also, what HP levels is a free flowing mandrel bent dual 2.5" system capable of? I'm wondering if I need to step up to 3" now... that would require new collectors on my custom headers though


Thanks for any help!!

i would switch to 3" collectors and true duals if it were me and run high flow cats along with the bullets

Spiral flows will be alot quieter. Even quieter than that would be traditional mufflers behind the axle around the stock location.

How much power would I lose with the spiral flows? Are they really that much quieter than the sweet thunders?

Well, anyone else?? How much are 2.5" duals good to? Will I lose any power with spiral flows?

Put the adjustable Borla with the QTP electric cut out and all your problems will go away. If you feel like being loud open the cut out. If you feel like being quiet close it up. Or you can slap on a Procharger and just have a whistle sound with power and no noise.

Urban Legend- I used to run a stock WS6 catback with a 3" e-cutout under the car. The new motor needs more than just a 3" catback... I'm contemplating over the axles TD's with cased mufflers or else maybe a 4" single catback.
