Help me find an ex system

i have to get rid of the flowmaster on the car its killing me on the top end,
im looking for something else to put on the car and so far alls i can come up with is a borla or edelbrock muffler.what other options do i have
the only other thing that has been suggested to me would be an import style stright threw muffler,which i really dont want to do,

btw dosent need to retain the factory dual tailpipes
chambered mufflers are a no go chamberd muffler+ turbo = not good

I have a Dnomax Ultraflo 3" inlet dual 2-1/2" outlet for sale if you're interested. $80 and it's brand new. This sucker is pretty much a straight through that is listed at 1200+ cfm.

not quite. It has coils inside that absorb the sound instead of chambers and baffles.

The Banks Power Pack system I had on my 82 was one of the best sounding exhausts I ever heard. But the dynomax muffler I replaced the banks muffer (rusted out) with sounded real good too.

Dunno. It was whatever Dynomax muffler fit my Banks pipes nicely. 3” in, dual 2” (or maybe 2.5” – I forget) out same side. I'm just saying in generally I like the Dynomax sound - not too loud - but by all reports I read 'back in the day' they still flowed as well as noisier ones. And it wasn't silent by any means.

A kid I went to high school with had a spintech cat-back on his 2000 SS and it was nice and quiet idling and while cruising, but when he got on it it got a little louder. I just really like those mufflers because they dont sound like anything else.

SLP two on the left. It's great if you can get past the looks. It flows GREAT and sounds good at WOT.
