Default stock or flowmaster?

Since everybody hates the flowmaster's, I was wondering if my stock ws6 exhaust is a better muffler or gives me better horsepower. The 80 series catback I got does sound good though. Just wondering what the crew thinks out there.

yeah there was a thread a few days ago about how much power the 80's series with held. I had the flowmaster ctback for about two years it sounds good too but when i wanted to unleash the power i just flipped the switch and the cutout opened.

I would keep stock catback and go with a cutout. Still looks stock. I personally think flowmasters are worse than stock.

flowmaster > stock in sound.. hands down

take me for example, i'm not gaining or losing anything by having a flowmaster, but it's my daily driver... i want it to sound nice, and i want people to know not to **** with the camaro

I was thinking the same thing, electric cut out. Should feel a difference in hp after that. Plus I need to ditch the hand held reprogrammer and get a custom tune.

That is a confusing statement. Why should a Vette be louder than any other LS1? If the Vette was that loud, why wouldn't the F-Bodys be just as loud?

true duals vs. y-pipe setup
true duals would be louder

It's highly unliekly that the stock OEM muffler flows as well as the 80 Seires. Plus the Flowmaster catback uses 3" tubing so is a much better bet even if youplan on using a cutout.
