My buddy doesn't believe me that Flowmaster is one of the worst cat backs for an ls1 f-body. Can everyone who knows about Flowmaster back me up? State your opinion on what you think is the best.

I forget which model flowmaster muffler flows poorly, but I believe its only one of the models and the rest flow pretty well. Everybody bashes them but you gotta love the sound and honestly I doubt most people would be able to feel the difference between a flowmaster and most other mufflers out on the market but thats just my opinion.

I have dual 40 series on my 67 and it is one of the best sounding street cars I have ever heard. Might be because its a bored out 400, or the huge cam. But it sounds badass. horrible drone at about 1700 rpm which is fine since it is never in that rpm range.
I was thinking about getting a LM and putting a 10 or 40 series in place of the resonator, not sure how it would sound though.

so i raced this ws6 and smoked it
the ws6 then gets a slowmaster muffler installed,
and i smoked him even worse.
the point of this story is
1. even the stock ws6 muffler is better then a blowmaster
2. disconnecting the muffler on a non-ws6 makes it faster than a ws6,
so,
3. having no muffler at all is better than a flowbastard.
so much for that stupid old wives tale about "backpressure"
maybe a loss below 2800rpm,
but after that, it is EVIDENTLY worth it.
this isnt an opinion to argue with,
its a fact to recognize.
by the way,
best performing exhaust?
any straight-through, i.e. GMMG, loudmouth, dynomax bullet..
and the flowmaster's cheap hollow sound doesnt hold a candle to the GMMG or sweet thunder. do yourself a favor and go hear some exhausts instead of taking pointers from that paisa at the local exhaust shop.
