X-pipe questions

[5.0_GT_kid]

Alright guys, when I do my next exhaust combo I will be using an off road X-pipe instead of the H-pipe.

I have been looking around at different X-pipes available and I see how the "X" portions are almost always different from one brand to another.

BBK

Dr. Gas

So now I'm at loss for what to do next. I was hoping maybe you guys could point me in the direction of which "X" pipe design will make the most power on my car (which will be a 306 with nitrous) or if it will even make any difference at all.

Thanks in advance guys.

To my understanding the mid section (in this case the X) is moved up or down in designed to gain the most optimal hp/tq (in the manufactures eyes/test).

IMO go for the cheapest. I've always heard with an X to run straight through mufflers such as the Ultra Flo welded ones.

 

[juiced_94gt]

get the mac piece, it fits good, is cheap and high temp coated, IMO all x-pipes perform and sound the same.

evidently, dr. gas x-pipes have been proven to make 2-3 hp more than the competators...i'm not sure where i've read this, but its been posted on here before...

also check out the PYPES XCHANGE.....its a regular x-pipe with little tubes comin out the side with a plate on them with wing nuts....so when u wanna go to the track, just pop the plates off, and u got open pipes.....PYPES had a booth at teh e-town swap meet last year and they had a fox body with this x-pipe, and their catack, and it sounded MEAN!...my buddy also has longtubes, dr. gas shorty x, and dumpes flows, and that sounded AMAZING!

 

[mricci]

you should check out the upr one too. Its a pretty decent and cheap one.

Juiced - I won't be putting anymore MAC pieces on my car. I have their H-pipe now and it's total crap.

Stprorolla49 - Thanks for the info man, I'm leaning towards the Dr.Gas now after that.

can you please elaborate on why you think your mac h-pipe is total crap. several people on this site constantly bash mac products, where as every mac part i've had has fit much better than the higher dollar counterparts they replaced.

do Bassani...mine fits perfect. Go x pipe if you run straight through mufflers, h if you run chambered. x + chambered = sounds like a dump truck.

The fit is pretty poor IMO. The exhaust shop had to spend about an hour just trying to get it to fit, and they had to cut the original hangers off and weld on new ones.

Not to mention it's aluminized steel and rusting out terribly

Don't get mac... Take it this way:
you get what you pay for.

funny I've had two mac H pipes and a set of mac headers and all fit great. Buddy of mine has mac long tubes and H pipe that have been on and off multiple times without issue. They may rust a bit quicker, although I've never had any issues with it, but fit has always been good for me. Not saying others opinion isn't validated, but poor quality hasn't been an issue with what I have seen.

I hear ya there, I got a buddy of mine that swears by MAC and has never had a problem with it.

I've heard that with MAC and BBK products, it can be hit or miss as far as the quality goes.

my mac prochamber fit well (new 3piece design)

x + chambered = sounds like a dump truck.

I have heard Dr. Gas pipes with chambered muffs and it sounds damn good. It depends on the X section...some produce a good sound and others dont. I have not heard too many good comments on the bbk style cross over...if any at all.

My vote, as my sig says, goes out to the D-pipe.

Picture of the cross over:

If you dont go with the D-Pipe , then i would go with the Dr. Gas. That was my second choice and i have never heard a bad comment about them.

 

[Nik_95Cobra]

Yeah when I was running the bassani x with the macs I was actually a little embarrased of the way it sounded, a bassani aftercat (straight through) fixed that though. Never seen a D pipe...looks pretty cool.

 

[mo_dingo]

I love my bassani w/ the magnaflow c/b. Sounds awesome....Wouldn't change it for the world...


But I like the transition of the bassani's and the magnaflows. The BBK is pretty much a smaller h-pipe and I have "heard" many bad things about the MAC pieces on this site and others.

I don't think I would ever own a mac product, personally. But that's JMO.

The fitment of the bassani o/r X on my car was absolutely perfect. The fitment of the magnaflow o/r x-pipe on my brothers 03 GT was perfect as well.

But the magnaflow is too damn expensive for my taste. I would go w/ the bassani IMO.

I have always had problems with MAC products. Go for the bassani X, fitment is perfect. If you get the aluminized offroad version its only 225 with free shipping.
