What mufflers you running and why?

I used Race-Pro mufflers from Pypes that came with a 409stainless 3" kit for my chevelle.

The reason I used them was the cost of the full system was very reasonable but I have been pleased. Interior noise is significantly less than the flowmasters it had before.

They might be too quite at times but I am sure my neighbors would disagree. The exhaust note is nice from behind the car. In front of the car the cammed LS valve slap overpowers the exhaust note. Inside the car it is reasonably dB levels. I can reasonably hold telephone conversation on the interstate due to the insulation but still get plenty of compliments.

My original plan was to run these until I decided to cough of up money for one of the Borla pieces but now I have decided to stick with this since it works out so well

I agree with your comment almost 100% .......

Except, that I was never planning on changing to something else. I have Race Pro's flowing through a Pypes 2.5" stainless system with their X-pipe. At idle and cruise it is not a resonating nightmare, but when you get on it, it is a simply awesome sound!!! It is my opinion that an exhaust system can brag the best flow numbers, but sound like crap......and in the end, entirely personal choice. It's like buying stereo speakers or choosing a wine
