Re: What is your favorite performance muffler?
Borla xr-1 ftw. They sound soooo good. They may be expensive, but they last forever. Aluminized mufflers will rot from the inside out pretty quick. Painted is even worse.

Re: What is your favorite performance muffler?
For me it would be Flowmaster---I have ran them on a 65 Mercury Comet Caliente and on my 67 Chevy trk. They sound great and have good performance.They are also priced right for folks on a buget.

Re: What is your favorite performance muffler?
I have 50 series Flowmasters on my Vette and love them. They are not too loud, and do not have the drone of 40 series. On my truck I couldn't tell you what they are, but they are louder inside than the flowmasters, but it's got a built 6cylinder and the pipes come out right in front of the rear tires, as opposed to out the back on the Vette.

Sportsman Street Part # 3332 2 1/2 Center with offset I had 40 series on my truck and to me they didn't sound right with my 402BB. I heard a set of Spin Techs with a BB and they seemed to have a deeper yet mellow sound. Again we all hear sounds differently which is why we have so many flavors of mufflers to choose from. I gave my 40's to a board member here...I think for free. Again...nothing wrong with Flowmasters...they just were not what I was lookin for. They are not installed as the Circuit Rider is still a month or two away from being finished. Project Circuit Rider... http://67-72chevytrucks.com/vboard/s....php?p=2964845

Re: What is your favorite performance muffler?
I like my 40's and they of course would sound better with headers and a crossover (like my old old truck) but there are too many trucks with Flowmasters in my area in my opinion. Kind of ruins it for me. I'm trying to save some dough for some Borla xr-1's $$$$. They have a way different sound than almost anything. Kind of exotic

Re: What is your favorite performance muffler?
My son has CherryBomb Vortex mufflers, they sound wicked when you get on it, but mellow at cruising rpm. Only thing, I wish they were stainless. I figure he will get maybe 3-4 years from them, but we installed them with SS band clamps so the 2.5" stainless pipe butts up to the muffler inlet/outlet instead of slipping in or over, so they will come out for replacement real easy! Nice setup. The headers are Hedman Elites with a ceramic type coating and the pipes are SS.

Re: What is your favorite performance muffler?
I would say Borla as well, had their cat back on my 06' GTO and it sounded awesome, but that coulda just been the 6.0 as well...

Re: What is your favorite performance muffler?
I personally think Borla xr-1's sound amazing with all of the other straight through mufflers second. Like pypes race pro, dynomax ultra flo etc. They don't mask the sound of the motor like a Flow type muffler does. They sound raw
