X-pipe Help

Reply #15 –
Heres some pics of the x-pipe hitting the tranny linkage. Didn’t realize it last night when I finished but its bending pretty hard. I wondering how it would clear a mustang, and if I could just bend the linkage. Problem #2 is you can see on the driver/side header and x-pipe bolt-up how it on the tranny I just squished it together so far so good but I’m not happy.
Thankyou for the advice Eric but unless I have no other option I don’t want to dent any thing. Hoping it will fit right but I might not have any other option.

Take your torch and heat and bend the linkage out of the way.
No one said it would be easy.I'm still not happy with mine.

I had to tep on my x-pipe for the same reason.My shift linkage washiznitting.No big deal,it was made by Pypes,and other than theat little bit of clearanceing,no issues,no rubbing,nothing..It's been great.It was well worth the $126.00.I have the BBK headers,and I think that there is a difference between the factory headers and the 1 5/8 BBK's.The size is bigger obviously,and the tubes are mandrel bent,nice bends,no crimps at all.Glad to hear you got your together,now just a few taps of the hammer and you are ready for action.

I wonder why people get "X" pipes? They are more difficult to install and they offer no real performance benefit. They do sound nicer - which is a definite advantage - don't get me wrong.

My X-pipe was easy to install.Actually,easier than an H-Pipe since it's two pieces,which makes lining it up with the headers really smooth.The X-Pipe flows better than the H-Pipe.The crossover in the H-Pipe becomes useless the higher the rpms.The X-Pipe has a consistant flow pattern and smoothes the exhaust tone also.I've used them both,and won't go back to an H-Pipe.

I have often seen issues with the "X" causing people install issues involving ground/transmission clearance - that's what I mean when I describe "installation" issues.

The marketing hype about the "X" pipe is starting to fade a bit. Here is what the Accufab dude said about "X" versus "H";

Quote
Here's a solid answer. We have tried both X's and H's, and the H wins on the dyno everytime. As to "why", I think it's because the X reduces the area (volume) somewhat (where the X joins) over the H, where there is no reduction. Just my guess.

By the way, Accufab is now offering Big Tube Headers (up to 2" primaries) for 351W's with any Windsor type heads, in '67 to '73 Mustangs.

I also read the MM&FF article and the "X" made no more power than the "H". If I was starting over I may choose the "X" because it sounds nicer, but I would not be expecting any more or less power.

I gained clearance with my X-Pipe.I did have to clearance it for my shift cable,but that wasn't any problem.Mine is 2 1/2 inch as opposed to the smaller factory H-Pipe,so That's not a fair comparison.I would have to use a 2 1/2 inch off road H-Pipe to to a fair test against my "X".Compared to my old factory unit,the X wins hands down.It all boils down to personal opinion.I have tons of ground clearance,My car sits up tall like your Cougar (in the pic),maybe a little higher in the rear.I'll read up on the "X" verses the "H" and see what I think.

It's still personal preference for sure. In the post there was a poll & more people chose "X" over "H" with no real reason except that I think "X" sounds cooler - like "X" games. Actually, they do sound better :grinno:

I have a wierd thing about pipes that aren't round ever since I flattened the bottoms of my long-tubes in my GTO doing a wheelstand (25 years ago) - you'll never catch me hitting a pipe with a hammer.

More Problems And No Time

More problems I couldn’t get the bracket off the tranny to put it on the bench and bend it so I did it while it was on the car and when I heated it up I melted the rubber grommet so it fell out I circled the piece in the pic and ill tell ya I didn’t even realize part of it was rubber so I’m losing my patience and even though I’m off tomorrow I cant even play w/it because my wife works when I’m off and I have to watch the kid(4 month old).
So I can’t believe I saying nor thinking this but do to my time situation I’m contemplating taking it to a tranny shop to make a bracket and while its there might as well give them my TRANSGO kit to install. So I’m kinda counting my losses here and thinking what’s this going to cost me.

Here are some pics of my earlier fix of frpp header and motor mount fab on the drivers/side. And just so you so I’m not so happy w/it I would like to get a better mount one day that are not so available.

Pic #1 shows the motor mount grinded away and rubber exposed which I was not happy with cause the header was so close I was scared of fire.

Pic #2 shows a piece of metal I cut up and shoved it in/above the rubber mount to weld.

Pic #3 shows pretty much the finished product though this is temporary for now after it was welded in and pounded in and excess weld grinded down.

I might have that bracket off the trans laying around... I just took a AOD out of my mustang and its still sitting around. Ill check when I get home if the bracket is still on it or if it got thrown away.

Bane Thankyou the only reason I could think why I had a clearance problem is a mustang motor must sit lower in the car angling the pipes just a little different and clearing the tranny linkage.

When I installed my MAC 2 1/2" H pipe I had clearance issues in the same spot that you're having trouble. I had to bend the shift linkage in towards the transmission. I did this with a big pair of channel locks and no heat. Also I had to relocate the cable bracket about a 1/2 inch higher. I pulled the bracket off and drilled a new hole. The H-pipe barely fit and took about 8 hours to do. I think I had entered the 7th level of hell when I installed it, lol!

So this bracket does come off then. It seemed like it might have went into the tranny. What’s the secret to getting it off then? I was praying on it a bite but didn’t want to break anything.

I'm pretty sure mine just bolted on. It's been a while... I guess I could jack up the car and take a picture. My h-pipe is loose right now (no heads) so I might be able to pull it out of the way enough to get a decent shot.
