Has anyone used this muffler? I am swapping out my stock exhaust on my 1990 Formula L03 to a Hedman shorty - 2.5 Y-pipe - 2.5 cat - 2.5 i pipe - all the way back. Is it loud? Would like a quiet muffler instead of a dynomax with good decent flow and close to OEM. The 2.5 system will first go on a stock motor, but later with all the mods s/b around 285 at the crank. HOPE.

If too loud, could I use a stock 350 muffler and not hurt the flow too much? I'm not into loud.

Thanks all.

 

that muffler will be very close to stock sound level if not a little bit quieter. That brand of walker mufflers is what gets put on every vehicle as replacement mufflers.

 

I used the Walker Quiet Flow as a Replacement on my GN, sounded really good. Louder than stock but yet still had the Deep tone....
