I was wondering if anyone has a picture of the inside of a Pacesetter muffler. Or could tell me if it is clear like a flowmaster ot is it clogged up like the oem? Thanks

 

Pacesetter makes a lot of different stuff. Exactly which of their mufflers are you asking about?

I had a couple of their 2-1/4" turbo mufflers on the '57 for several years. When I took them off, I gave them to a fellow racer with a '68 Camaro 327 4-speed to replace the header glass packs he'd had on for around 20 years. He immediately picked up 3 tenths.

 

It is just a basic single inlet dual outlet muffler for the tranverse mounting.

 

The one that came with my Pacesetter cat-back is the typical chambered/perferated tube turbo-style. I didn't use it because I figured it wouldn't flow as well as a Flow.

I don't know how quiet/loud it is. I'm dinking with the '57 exhaust right now, I suppose I could slip it on and see how it sounds.
