Best place to buy qtp cut out What size should I get 2.5 or 3 and should I get oval turndowns what's the benefit ? Benefits? Some gains in power at the wheels. Results will vary but I picked up 22 on a stock LS1 years ago. Expect more noise, of course. On my SS, I ran them open all the time.

They just direct exhaust away from your car, keeps from getting build up on the underside. maybe funnel the sound a bit Re: Best place to buy qtp cut out I found them for $458 with remote, is that what they are going for any place has them for cheaper ? That's about what I paid with the tips and wireless remote, I honestly didn't shop around a whole lot, but the couple I checked were all about the same. Shipping was the deciding factor Re: Best place to buy qtp cut out Thanks for your help I will order them this week ! They just seem so expensive or maybe I'm just being cheap with my money ever since having kids One last question should I get the 2 1/2 inch or the 3 ?
