My mac (ya ya, I know most of you hate it) 3 inch cat back and 3 inch pro-chamber arrived today, man this is BIG exhuast I also got my msd 6al,spec stageIII clutch disk,Aeromotive bypass regulator,pump,and both filters. Got a bunch of misc.....stuff too. Now all I need to put this together is some fuel line and fittings (little stuff I'm forgeting too) and some motovation.

I sold my complete 2 1/2 setup so I would force myself to go with 3 inch, 581hp imho requires exhasut that big, just me though.

Your motor absolutely needs 3" exhaust. I switched from 2 1/2" to 3" and gained power from 3700 rpm up with my NA 306. It was down 10 ft-lbs at 3000 but up 10-15 ft-lbs above 3700. Peaked at 363 ft-lbs at the wheels at 5200 rpm.

Yeah I'm very happy with it. I'm running a custom 3" x-pipe and 3" Dynomax Ultraflos dumped.

Mike you should see my 4" stuff...

Jesus christ Rick, 4inch!! Wow, is it on the car yet? Dumped I assume?? Demongt, I have yet to put it on the car, just got it yesterday. I'm running 275/50's on 15x7's with 5.5bs. Hope they fit, if not I will run a spacer. I have 3inch studs on the axles so I wont be scared to space them out some if I have to.

 

[Rick 91GT]

Most likely going to try it right off the headers..lol

I have some pics of the 4" I.D bullets I'll see if I can post them...

 

[tvmango]

I have a 6 inch.........










exhaust...JK

 

[tvmango]

I want to meet you this summer,, so we can swap lies.....

 

[SmockDoiley]

ive thought sometimes about getting 3 inch because of my power levels. But for everything I change to get more power I screw up my driveability. I could make more power but then I lose more on the low end. I guess I should just stay where I am.

 

[IMissMy93Fox]

I think 3" should suffice for your power level... I wish I need some 3" stuff. Make sure you put up some sound clips when you're done

 

[SuperStang83]

I'd love to hear a clip of that when you get it together!!

Its got equal lengths, offroad x-pipe, and dumps right now so its quite loud and I imagine not very restrictive.

 

[88stangmangt]

most of the honda guys have 8" exhasut.
