www.airram.com you will find headers for your 3.7 jba makes them

 

Well other then it being obscenely loud it will be fine as long as you keep the pipes the same size as stock. If you put too large a diameter pipe on you will lose exhaust velocity which will hurt your performance, magnaflow has good simple chart here http://www.magnaflow.com/wideopen/performdata.asp

6 Cyl's should be quiet!!!

 

not my 6 cyl it sounds like a hemi on steriods and it kills most v8s nothing funnier than running a v8 truck or car and kickin his ***. then seeing their face when you tell them yours is a v6! HaHa

 

Must be that throttle body spacer and Tornado giving you the edge. As for sounding like a "Hemi on Steroids"...We just don't have the firing order to make that happen. As in, our firing order only has 6 numbers.

Personally, I have grown to hate the sound of my Flowmaster. It's loud, unrefined and drones at almost any speed. I'm going to replace it as soon as I can find a deal on a quiet aftermarket muffler.

Loud and fast = fun
Loud and slow = white trash <-me right now

 

Not running flowmasters actually blew it out. Running a dynomax race bullet. as far as the spacer and tornado they don't do much as far as power increase just change where my power band is. I have a few custom made parts on the truck i haven't listed. buddy of mine owns a speed shop you could say my truck is his guinne pig. i have custom made pistons, lifters, rockers, crankshaft, and cams plus it has been bored .030 over and has a custom made shift kit in the trans. basically it is a v6 stroker motor.
