If your looking for a muffler with some performance gain but not too loud, then check out the #12286 Magnaflow muffler.

These mods make the 3.7 feel like night and day from stock, while its no hemi, it sure does feel like it has a bit more power. I wouldnt bother with a computer tune, there isnt really one out there for a 3.7 and lets face if you wanted lots of power you would've got the Hemi.
Thanks for the info on the flowmaster mufflers guys. Anybody have a link to some video clips with these in place? Would love to get an idea of the sound before taking the plunge. Do you guys add a tip as well or leave the end pipe as is?

Re: New member with a 3.7 GC - recommendations on mods?!

every sound clip that I have heard of a 3.7 sounds kinda ricey... in person, mine doesnt at all. Has a deep rumble and even the "bubble" or "underwater" sound that mustangs get with the proper exhaust setup. I also put a 3" tip on mine for a little added touch. It looks good imo.

Re: New member with a 3.7 GC - recommendations on mods?!

as far as computers go Jim @ MHP can tune urs to make it better not sure if they can tune the 2010 you might want to check with him

you can always upgrade ur shocks to bilsteins for a smoother ride and even lower it for a better stance

add some wheels and that'll set it off just right

debadging is one of my favs

HID lights are always a plus too

Welcome btw

Re: New member with a 3.7 GC - recommendations on mods?!

he has a group buy going on in the vendor section but he did mention that it's a lot more gain than a CAI and throttle body ... haven't seen any actual proven numbers ... once I get my tranny problems sorted out I will be sending in my PCM for a tune

Re: New member with a 3.7 GC - recommendations on mods?!

my magnaflow sounds like heaven at low low RPM.

once I step on the gas, sounds like a crappy V6.
