Everyone that I have seen post on here with a leaking slip fit primary always mention something about sanding it down. I did not sand mine at all, just used some muscle to get it in there....no leaks here AT ALL. Mine were close to the k member, but new poly mounts fixed that, as mine had collapsed after 70k miles of hard use.

I had some issues with mine, but Jet-Hot was there, better than any company that I have ever dealt with. They even called a week later to see how the install went. They even cut me a sweet deal on the extensions because of a few issues that needed to be solved, I did not even ask, they offered.

The hookers are known for hanging lower than the jet hots, that is most likely why you got better clearance for your car. Having the flange rotated with the flat side up is not a good idea if you are concerned about ground clearance, that is why they are like they are. All in all I would suggest that everyone that gets LTs to go with a custom y-pipe because they don't cost much more than the ones you can buy premade. Plus they will fit alot better.

 

i froze mine slipped right in also used some duralube

no leak at all

 

the new pacesetter longtubes for lt1 have no slip fit

 

>How did you freeze yours ?
I wish I did that , but it would have been easy for me ... just put them outside for an hour or 2 friggin Canadian cold front .

 

I dont' think anyone said they ONLY made slipfit longtubes......just that there isn't any easier way.

My install was the oppsite. Had to cut 1/2" out of the K frame on the pass. side. My motor mounts have less than 6000 miles on them.

 

all i can say is that jet hot has excellent customer sevice i bought mine back in like july and the first set he sent never made it here i guess they were stolen or lost but they promptly sent me another set of headers at no further cost. i think that if 2 sets didnt work maybe there is something wrong under the car. everyones engine bay is different.

 

I was in the GP for the very first batch and was quite skeptical at the time -- no one had installed them yet...



As you can see from the pic, there's plenty of floorboard clearance on the driver's side. My slip fit primary had never leaked.

Install cost: $0 -- I did it myself.


As for the slip-fit primary now... I have replaced it with a 2-piece custom-bent one for working around some supercharger tubing.

Jet-Hot coated this piece for me as well, but my craftsmanship wasn't quite up to par with theirs -- mine leaked a little. I threw a t-bolt clamp on it and viola, problem solved.

Jet-hot, you guys rock!

 

Mine are still in the box.
