    So the other day i was under my truck checkin for leaks and saw some black where the y-pipe meets the first pair of cats, the driver side had more than the passenger side. this morning i replaced the crush gaskets with new OEM ones. it was tough getting the gasket to fit well since its an aftermarket y-pipe but finally got it to fit right

    Cool! I meant to tell ya, anytime I replace gaskets, I use some Copper RTV. I have never had a leak. :) Something to think about if it happens again.

    Wow, just did the same today. I put those OEM gaskets in, and felt was still having leak. went to a muffler shop and they suggested same deal. Works good. I got the Copper one, says withstands 700 deg. temp and safe for O2 sensor, which is located right beneath that flange.

    Glad you fixed your leak Tacoskim...

    I am still switching to DT Lontubes. Deal is, the Mechanic at muffler shop, who does good work, JHODGE knows the place, but anyways; He could not believe the gap between the manifold and the head. He told me I should switch back to the JBA gasket, and that he needs to cut the flange so that to releave the stress from the warp, and that would allow me to tourqe down the flange to specs. :confused:

    Dude, I dont know. And the icing on the cake is, even though I cancled my order with JBA, being they were on back order, Today UPS stops by the house and drops off a brand new pair of JBA Gaskets... How Ironic.

    But I'll be damn if I cut that flange, no matter how good this guy is. I would feel like Im jimmy rigging my damn truck. No Go...

    So I decided to wait til tax return, Install Longtubes w/JBA gaskets (Better quality than stock) Get new OEM crush gaskets, apply a liitle RTV copper, and tourqe it all down to specs. After installing an O2 Bung of Coarse:D:D:D

    What you guys think. Have I lost my mine, or do you think this is a way to get it right, for good???

    Sounds like you have it all planned out. One thing, what makes you say the JBA gaskets are better than the OEM gaskets for the mounting between the head and the header? I have always used OEM gaskets on that junction with great results (no leaks).

    well i know that when i used to build domestic race engines..mainly stuff for weekend amateur drags and hod rod classics..we used to have alot of problems if we didnt get the gaskets to match up just right. sometimes with the aftermarket headers, the exhaust ports are a little larger than they are on the heads themselves. i found that if we used a gasket that fit tight around the exhaust ports on the heads, they would often "eat" away at the gasket hanging into the header. which would almost always lead to leaks. so we recommended that the gasket match the header ports and not the heads. that is of course if the jba gaskets match their headers appropriately.

    Ok. I have heard the same thing, but never experianced those problems. Seems that any leaks I have encountered have been at the "Y" pipe. Personally, If the header flange is thick enough, and machined flat, OEM gaskets should work just fine.

    Are you using an aftermarket manifold or stock?

    But yeah, that was in refrence to my experience with JBA Headers.

    JBA Gasket and new header= Tight seal, no leaks.

    OEM Gasket and Header= Very anoying leak, and black soot on manifold, Pain in the ass:mad: LOL...

    Hope I cleared that up for all..

    my jbas are bout 10k in still strong.. using the jba gaskets is a must when using the jba headers... like debighi said, want the gaskets to match up with the header, then use some good silicon around it

    Yeah I here you. But the funny thing is I noticed the warp after I've been running the JBA Gaskets. So my conclusion is I got the runt of the litter when it came to production. I know im not the only one. Im glad your's are holding up. Im gunna miss the note they produce. DT Long tubes better represent.

    I will resurect this post in late Jan-Feb.

    Oh and JHODGE, it's up in the air for spare parts LOL, but definately will hit you up when install comes into play. I will be doing Coilovers at the same time, since I will have the lift available. Should make for an exciting day.:D:D:D

    oh im sure you will definitely be happy with ur long tubes... if emissions wasnt such a hassle here i would of went with the long tubes with stock y-pipe instead of the shorties with the pipe-bomb
