Technical Best sounding mufflers............

I run open headers around town (most of the time.......we got cool cops & lotsa Harleys!) Rest of the time dual 'Blowmaster 40's ran TO THE REAR VALANCE and get NO drone on the highway.(on my M-word pony car)
Best sounding 327 Shivel-lay I ever heard was my high skool buddy ran round truck mufflers with turn downs...on his 55.

Thanks for posting that. I love the wicked idle. Thats how I want mine to idle.

 

A wise man once said "Build the engine and the exhaust note will work itself out."

 

My bad!.....
I deleted my post...

 

i put a 24" magnaflow on my wife's new truck, and it was TOO quiet!

 

I have a pair of good flowing 2-1/2" Borlas, H-pipe & 2FT of tailpipe out the right side. At first they were too quiet, but have gotten louder with age (maybe). With the offset tubes there's a perforated 'S' through it, a broom stick will slide through it.

 

Personally I ‘ve always been partial to hacked off mid year sidepipes, just the right amount of boom and wap!
