Anyone have experiance with these? Be going on on ss/sc. I been having an loud ass fart can for the last 4 years and Im sick of the loudness and riceyness.. Thanks for any input

 

i have them on my 1968 firebird so i cant really compare it to ur car but they are loud as hell on my car

 

Really? Damn I might pass on this then. Thanks

 

yea 40 series are the second loudest muffler flowmaster makes.

 

I've ran 40s on my Mustangs. They're not too terribly loud as long as you run a catted pipe. When I went with an ORX, they were very loud. Sounded good though. I have no idea how they will sound on a Balt. I've got an off set magnaflow muffler that I just took off my car so I could install a gmpp catback. I'll let the magnaflow muffler go for cheap if you want to try it out. You can hear it on youtube under "mach1spd" if you're interested.

 

Yeah my old GT had a Super 40s and it was really load. Think the GMPP catback will make a diff being 2.25?

 

How cheap? You have a pic you can send me?

 

What resonator do you have? Put it on and see what it sounds like

 

Not really. It does have mandrel bends over what I had, but not enough to make more than a a couple/few extra horses difference. The biggest thing is that it weighs literally half as much as the custom set-up I had with the heavy glasspack and magnaflow muffler. Sounds better too.
