I know this may seem sacreligous to some of you but can a mustang h- pipe or x pipe setup be used to make a true dual exhaust for our cars

------------------
Silly mustang's speed is for F-bodies

 

u could possibly cut it up into a bunch of peices and maybe makes something out of it but it would make more sense to make one cause the x-pipes wont fit at all

Borg Warner T-5 fresh rebuild
10-bolt 3.73 Richmond gears rebuilt GM posi,
formerly BW 9-bolt w/3.45 gears(broke it)

400 sbc and a 6 spd in the works

 

Just get a universal x-pipe. Dr. Gas, www.drgas.com (I think) makes them. You can either get just the actual x or the x and the pipes at each end of it. Magnaflow also makes them, but the Dr. Gas design looks a lot better to me, plus look at all the professional racers or race classes that use them (I can't remember which it is).

Also, mac makes sort of an x-pipe substitute. It's basically a hollow box with two inlets on one side and two outlets on the other side. They claim it's good.

 

whats magnaflow's website? and whats macs website?

 

I forgot. Do a search on google for "magnaflow mufflers" and for "mac performance". Oh, camaroman85 had a great idea! instead of an x-pipe, use a large dual inlet, dual outlet cat for a crossover--you kill two birds with one stone: extra performance plus it's legal!

I would so do this if I didn't already have my exhaust.

Tell me more about the dual outlet inlet cat

 

Here's the link to the post that cort351w is talking about.

I'm the one who explained why it would be a good idea.

Seriously, I've always wondered why nobody has thought of it. I was gonna have my local shop do that on mine. I thought I was gonna be one of the few to think of it. Dang nabbit!!!!! Now the whole country knows!!!!!! My secret is out!!
