Schoenfield makes a muffler similar to the pic above. They also make it in a collector insert that works great.

I have the Insert's, works pretty good. 4" aswell, just takes the tone down alittle...
Custom spec build headers, didn't want to chance the added length with the muffler.

Has anyone tried the schoenfields on a drag car? We had to run them on some dirt circle track cars a few years ago, and they toned them down some. Seems like they should work good in drag too..

I run the Vibrants. Not sure how you can get much cheaper than $75 each for a stainless muffler.

I run Magnaflow race mufflers. Straight through design. No baffles, no louvers etc. Without the mufflers, I need ear plugs just to fire up the engine. Now after a day of racing with no ear plugs, my ears aren't ringing at ht end of the day.

Dual 4" in/out.

Me and 3/4 of the cars at Greer Dragway has been running them for about 10 years now. Track has a muffler rule per a county ordinance. I wouldn't have a car without them.

I have the 3.5" by 6" long schoenfelds on my 434 SBF. Running supercomp headers with 3.5" collector. I cut the 3 bolt flange off and used a straight band clamp to attach the schoenfeld to the headers. I notched the muffler and put a hole in the band clamp around the O2 sensor bung, so that helps keep it all together without getting loose and coming off the header. They toned it down a little, but not much. My class required mufflers. Just don't stick your fingers up inside the muffler LOL, those sharp edges in there will get ya.

I have been running the dynomax bullet mufflers for years and I like them a lot.
