Jet-Hot long tube troubles

I can't get an answer to my questions after emailing chris, so I thought I should point something out to those buying jet-hot long tubes.

Notice how far below the top of the header tube the square is... that's when resting against the A4 cross member.

I already purchased 3" exhaust tubing, 3" mufflers, etc. And now none of it will work.

looks like you might need to do some bending get a torch and manipulate the tranny mount

Not gonna happen. I ppaid $500 for a set of headers. They should fit the car. I shouldn't have to make the car fit the headers.

Chris at Jet-Hot didn't reply to you at ALL? That is pretty uncommon, he is usually very good about things like that.

he has since replied, and we are working on a solution. I think the design needs to be changed in all honestly. It's nice that they hug the body for more ground clearance, but when it dumps right inline with the trans cross member and is about 3/4" too high to run a pipe from...the ground clearance, to me, becomes a non-issue.

what about getting an aftermarket tranny crossmember i think those have a smaller flange and no lip maybe that would give the clearance

still got hte bolt heads to contend with...and like I said, solving an install issue with a ready-for-market product should not include the words: big hammer, torch, bend, or the phrase "why not go buy..." unless these "adjustments" are spelled out to potential purchasers

trust me i feel ya bro but, the damn things are already on i think i would try to make them work somehow even if i had to spend a few more bucs mine will be here in a few days i hope i dont have these probs but i got a lift and a torch so iwill definatley be doing some fab work

if it was me i would just grind that lip off the cm i think that would clear enough space for them and i dont thin it will hurt the structural integrity of the cm

Thats pretty common for the Jet Hots....take a look at my pics. The problem is even worse when you have a Global West Track Link installed...the muffler guy had to make a mendral bend so that the piping would turn away from the tranny crossmember and clear the track link. I went with 2.5 inch tubing.

Actually, that won't be enough space.

I have dual 3" piping as well, with a cutout bolted to each header and an H-pipe. My mechanic grinded the cross member, but it still wasn't clearenced enough.

So he modified the flange on the driver's side cutout and got it to work. Took him awhile with the welder and torch but he did flawless work.

It is really tight in there. I wrapped the brake and fuel lines there with some heat shielding for protection.

I had the same problem with my install. It was a torch, grind and modify as needed sort of install. The price and quality of these headers are worth the fit issues. It's not perfect but it is workable and worth it in the long run. Grind or torch all you can off the trans cross-member then drive the car with open headers to an exhaust shop. A decent exhaust shop should be able to custom make or modify a y-pipe as needed to work things out.

i am going to run an x-pipe wth mine and dual mufflers

Get ready to be pissed. I looked at my headers last night. It looks like I'm gonna have fitment problems too (I have a 6 speed).

Is this a problem with the newset batch of them?? Seems like I didnt hear any problems from the first couple of people that got them, but I could be wrong. Mine are on the way, and I hope I dont have this much trouble with them,

i heard A LOT of people were complaining about the slip-on primary causing an exhaust leak..........people were trying all kinds of band clamps and stuff to get it tight.

ive got everything done so far........all old exhaust stuff removed...........AIR removed........EGR removed.........new plug wires routed (what a friggin PITA!!!!!!!).............im just waiting for my jethots to arrive so i can put them in.........hopefully mine wont be a nightmare like some peoples.


anyone else who routed plug wires in stock location..........were your passenger side wires really close to the power steering pulley?.......there is only like a 1/4 inch of clearance.......hopefully the wires dont come loose and cause problems.

Once I get a BMR K-member that damn slip joint is gonna get welded together.....I get leaks under load. :mad:

If your motor mounts are in bad shape it will worsen the problem you are having with clearence to the body. I did have to alter my cross member to work with my Y pipe. The slip joint use some high heat copper gasket maker and that should take care of it that worked on mine. Steven

>Would it help to shim the motor mounts ?
That way you will have clearance for the Canton oil pan and JetHot headers at the same time .
BTW where do you get motor mount shims anyway ? :confused:

I was part of the first batch. No exhaust leak with the slip-on primary. I stepped down to 2.5" x-pipe and had very small clearance issues. Those issues were fixed by replacing my tore-up, smashed, old motor mounts with prothane ones.

When you guys say clearance issues were cleared up with new motor mounts, I assume you mean clearance between the motor and strut towers and stuff? Doesn't make sense to me that new mounts would solve any clearance problems below the car because a worn out mount would actually sit the motor lower in the cradle and create BETTER clearance under the car...putting fresh ones on would raise the motor back up tighteninf the headers to the underbelly

When you look at which way tho motor twists when torqued the right side mount gets smashed down and the left gets streched. The right side will collapse over time. The rubber deterioates and compresses. And yes you will gain clearance if you replace the mounts as you are changing how it sits left,right.up and down. Poly mounts work the best. And im not saying this will give you gobs of room but you could gain a half inch or more on the left side where you need it. You could also possibly shim it on the right side but i would not shim a used stock mount. Im not shooting from the hip here cuz i have the jet hots on my z and a collapsed mount. Steven

Update:

I finished my Jet Hot and Mufflex install. I ground the tranny member, but didnt need to. It fit fine. The problem I am having is the passenger side headers hits the body by a "c" hair. Other than that is looks cherry.

Had the same problem and I just cut the lip off the tranny mount. I also dented my pipe there abotu a 1/4" so it would clear the tranny mount bolts. Really not a problem to me for the quality of the headers.

A guy I know who installed it had it REALLY close to the frame (drivers side, of course). Once he installed it all and drove it, it sagged down some...probably from the weight of the exhaust pipes and the tubes heating up.

Another guy I know (Hookers) had to grind the cross member :

So, some manipulation may be necessary. I have JH's ready to install once I get the heads on. I don't look forward to it.

I put those Jet-hot headers on my friends 96 SS with an A4 with a mufflex Y-pipe. Went in fine and doesn't hit anything. no leaks at slip fit primary. Quality is excellant.

i crushed my pipe to make it clear the tranny mount. works fine with me. i have aluminized steel all 3" with side exhaust. i wouldnt want to do that to a $300 y-pipe. no matter if you grind the tranny mount, the bolds are still in the way.

I have never had a leak from the primary slip fit and my headers fit fine with my 3" IRS y-pipe.

I have had these headers for 3 years now.

FWIW, I just received my Jet-Hot LTs (93-97 LT1 w/emissions bungs) about two weeks ago and have yet to install them. I test fitted the slip fit primary and it's not a tight fit. I can slide the slip fit together by hand and the pipe is free to wiggle ever-so-slightly. Looks like I'll be applying a heavy dose of RTV at installation...oh well.

After I had my headers Jet Hot coated, I had to sand down the slip piece. It was simply to tight.

Jet hot made an outsanding header. To bad they dont make a y pipe, so I had to make one.

Are these problems only with M6's??? Has anyone tried the new Y-pipe's in Summit that fit Hooker LT's??? They should work, right?? I have set thats going in soon so I wanna know what I'm lookin at. Thanks

I like how the cutout exits are turned down some:cool:

its a waste of 200 bucks, I tried it and had to put a dent in the drivers side pipe, It was a 6 hour install on a lift:(
my buddy is a mechanic and he helped. The fit was horrible!!!

I would have cost you less than $200 and under 2 hours for a muffler shop to build you a y-pipe and it would have fit perfectly.

I know:(
The sales guy at sumitt said it was an excellent fit, Thats why I ordered it, I tried to call them but they don't care, I can't return it cause I had to put a small dent in the drivers side pipe to clear the crossmember bolts :(
