Can I have a Flowmaster Muffler installed on my 2001 Bonneville ? Would this increase performance ? HP ? Is this a good idea ?

Ridic

I love the Flowmaster on my car. You can definitely have one installed. I am actually running the 80 series crossflow for an LS1 car. I am not sure what one would fit in the stock muffler location. My Bonneville'* exhaust was modified when I bought it so when the Supertrapps shot craps I had the exhaust reran from just after the resonator back. There are people that show the Flowmasters don't flow as well as some other brands but I am running them on all 3 of my cars and do not feel I am losing any horsepower because of them. As a matter of fact my car seemed to lose a little low-end and gain top-end when I put the Flowmaster on. Of course then I put the smaller pulley on and now it has lots of low-end.

Not-Rdy, what year is your Bon?

It'* a 1996.
