|kleen56||This is another one of those controversial subjects of what's better. There is no definite answer. It's what you like and works for you. One person may run one brand and another swears by another. I'm not into racing my streetrod on a track or quarter mile strip, but I've run several mufflers experimenting. I would never buy Magnaflow again because they were expensive and didn't sound good. I've been running Flowmasters and the sound is nice, quiet at cruise speed and opens up when on the pedal. As for performance, really can't see a big difference with any of the brands I've tried particularly running a Small block. I guess some people feel the louder the exhaust, therefore the faster the car? Maybe there is a difference with the big blocks, a different story. Most of the gassers I've seen run glass packs! Just to put a mix into it... LOL..|

|vinniekq2||85-130 miles each way with a 4.88 rear gear and probably not legal muffler?|

Learn something new everyday. Hate it when the parts sites don't mention that you'll need this or that to go along with the part.
Yeah, it's a streetdriven gasser (sbc 41 Willys) and I drive 85 miles or 130 miles to the track when I race.
Thanks for your reply.

2 inch primary pipe headers are too big to fit the stock exhaust bolt pattern on small block heads
Thrush professionals are a race muffler for race cars. Is this car a "gasser"

If its a "gasser" use thrush professionals.
2 inch headers on a small block requires adapters

Despite the obnoxious noise and drone, (no)Flowmasters consistently rank among the most restrictive mufflers in unbiased magazine tests.

I hope you're going to a BBC to match those 2" headers!
FM muffs have gotten a bad reputation. Whether it's deserved or not, I cannot personally say, having never run them back-to-back w/other muffs w/no other changes. If you believe the manufacturers of other mufflers, the FM's suck. There might be unbiased tests that have been done, I'd only use that, not ANY manufacturer's published numbers. Numbers can be made to look however you want them to look. Old saying: There are lies, damned lies, and there are statistics. Same thing holds true here IMO.

Flowmaster or ?
What's a good "muffler" for a streetable gasser? Running flowmaster 10's on 1 5/8" headers now but going to 2" headers. I've heard some bad commits on flowmasters. I'm guessing restrictive?
As to headers, I'm thinking tri-5 fenderwell gasser headers on a sbc 41 Willys?
