Im wondering what affect would a full 3 inch exhuast and long tube Headers have on HP and Torque on a stock engine. And what would it do to this setup:
Cobra Intake
GT-40p Heads
E303 Cam
1.6 Roller Rockers
65mm Throttle Body
C&L Flowtube w/ K&N Filter
76mm Mass Air Meter
24lbs. Injectors
3:55 Gears
Underdrive Pullies
A/C Delete
Smog Pump Delete
Fuel Pump 190
Fuel Regulator
2 Core Aluminum Radiator
Black Magic Electric Fan

I think 3 inch is overkill for that set-up, I will have 3" but my motor is slightly more pumped up. 2.5" should suit you just fine, but longtubes are always good. ![[patriot]](graemlins/patriot.gif)

So I guess they just sound tight. My friend has 3 inch exhaust from the headers and his shit screams, but his car is hella fast. He says he bored it out but I dunno

yea, I hella want my car to have a hollow, deep sound. But I dont know how to get it. I thought a 3inch exhuast would do it but I dont wanna kill my power. Anyone have any suggestions? Would this sound DEEP and HOLLOW?
BBK Ceramic Long Tube Headers 1 3/4
Mid X-Pipe (Off road)
Mac Mufflers
2 1/2 Tail Pipes
Guys Make suggestions. Right now i have 40 series flows, stock headers, off road h pipe, and 2 1/2 pipes and its just loud, theres no deep rumble

Run 2 chamber flows, that would get that hollow sound and if that doesn't do it an h- pipe will also help, but then you would have spent lots of doe, just for the sound!

like everyone else said 3" is overkill, but definetely stay with longtubes... If you have the $$, bassani l/t's, matching X, and some good flowing mufflers...

Which muffler will give me a Deep, loud, hollow sound. Hooker, Magnaflow, Mac, Dynomax, or Borla?

3" is not over kill for a 351w unless you are building a near stock or very mild motor!
