ok guys i have hedman longtubes.. now i dont care about being legal so here are my thoughts. 3 inch piping. 2 cut outs right after the headers. summit h pipe then dynomax bullets. all before the axle. wat do u think?

 

I prefer x-pipes over h-pipes. Also im not into the super noisy stuff so the bullets have to go and something more muffled like hooker aerochambers should go on. What would be cool is if you had pipes comeing out the sides like two on each side.
Otherwise i guess it'll be fine.

 

It will be very loud. I wouldn't bother with the cut out's either, the Dynomax bullets aren't what I would call restrictive.

 

would a xpipe be harder to fit.. i would like the exhaust to go as smoothly as possible cause im doin it.. ill also have SFC. an aftermarket Tq arm to get in the way of stuff

 

big block or small block?

 

smallblock 383 480hp crank hp not brokenin.. built for n20

 

go with that setup without the cut outs and im sure you'll be very happy. im sure the cut outs arent neccesary with bullets because 8 and 7 sec cars run similar setups with bullets.

 

Thats the set up I am running and if you have a pretty big cam, which I assume you do, then don't plan on talking to people in or outside your car. It is defeningly loud. I have hooker 2210s, dual 3" and a set of dynomax bullets and dumps. Loudest car I have ever herd on the street, EASY. Too loud. I am making another exhaust this winter. My motor is supposed to make around 510HP. I am going to go with dual 2.5" pipes and an h or x, not sure yet. Then have them come togeather behind the back seats if possible and go over the axle and dump back there someplace. Oh also slap on some spintechs or something once the pipes are back there. I have to get these pipes off.

I too am running an aftermarket TQ arm.
