GOOD EXHAUST

torch93 · Jan 15, 2011

trying to figure out the best exhaust for my stang, im currently running m.a.c headers(swamping out soon), a bbk H pipe, and 40s flows, all 2.5"...all of this was the setup i was running before i change engine.
i was running on straight H pipe and felt a differnce, faster rpm rise and lil more power, ...
1)headers? long tube, shorties, or equal length? does brans matter?
2) H pipe or X pipe?
3) what size should my pipping be?

dont know if it matters but i have a 342 stroker with 10.5:1 comp. with afr 185..
sorry for the novice questions
T.I.A

If you want to switch Why not get a set of long tubes , X pipe and a set of straight through mufflers.

this is a very good idea but also consider Mac long tubes, O/R X pipe and S4rge on youtube,

Long tubes, o/r x pipe, and a set of magnaflow mufflers through 2 1/2 tailpipes. And you will be amazed at the pick up you will see along with much more torque!!

Sounds good, name brand x pipe? Or get a custom made? What size is good?

What about electric cut outs?

i see alot of people do fine with 2.5 in exhaust, but with the about of displacement you have i dont think 3" would be bad. could be wrong. Id run Longtubes into xpipe with dynomax bullets or outlaw race mufflers... but that might be too loud for your liking

2.5" exhaust is plenty!! Go too big and you will lose that low end torque and throttle response you want! search around and see if you can find a dr gas x-pipe for long tubes, if you cant find one get something along that same line like a pypes brand. I've also heard good about the mac pro chamber (i think thats the name). And a set of magnaflows part# 11236 will be the muffler you will want to go with. Decently quiet with all the performance gains you need!

Oh and Cut out are up to you but you will hate how much they leak and cause turbulance in your exhaust when capped. .02 cents

I don't see where you say what you do with the car. Track or street mostly?
Lowered?

IMO, leave the longtubes to the drag strip guys. They hang pretty low.

As i said in your other post, use bassani equals, which will work with your current x or h pipe.
The quality is far superior to any mac garbage.

Oh didn't know about the clearance, ya it's a street / dd car... And it's gonna get lowered , I'm thinking about the equal lenghts.. Bassani might be for me..

bbk 1 3/4 long tube ceramic coated w/mac prochamber h-pipe mac mufflers 2.5 w/3.5 stainless tailpipes no clamps or welding here is a pic the long tubes are really low no speed bumps for me

heres a pic of the tail pipes if you dont go with long tube go w/equal length shorty
