Dezod Green Header install problem ***UPDATE w/PICS***

***UPDATE ON PG 3 w/PICS***

After waiting 2.5 months, I finally got my Dezod Green Headers! Couldn't wait to get them on. Took it to a shop and after a few hours, they ran into an issue of the down pipe hitting the transmission mount. They had to file down the mount a bit but the pipe still touches. All the other bolts, mounts, vclamps are tight, just the down pipe touches the tranny mount right after the v-clamp. Hope the pictures show this problem clearly.

Due to the down pipe touching the mount, it rattles like crazy. Not sure what to do...anyone else run into this issue with their green headers? Was this installed incorrectly? I took this to a reputable shop that is known to work on Lexus cars. They recommend I take this to a muffler shop and have them cut and extend the downpipe a bit so that the bend does not touch the tranny mount. Im thinking I shouldn't have to do this with the Dezod headers, especially how highly rated they are. Dezod green owners, please chime in!

TIA

That's interesting. Granted I got mine over 2 years ago, I didn't have any fitment issues that I can recall. Maybe someone with a picture from underneath can help to possibly see if something isn't installed right or can see some sort of defect.

I'll contact Dezod to see what they have to say. It's a quality built header...just not quite right at one spot that ruins the whole experience. Perhaps the jigs they were using to make this moved a bit and caused this to happen. This really sucks...

can you take a picture to see the clearance between the pipe and tranny mount? Mine is already touching so it's rattling a lot. Not sure if it is installation error or whatever but just want to solve this issue so I can enjoy the product.

I would expect the Ebay headers to be off but not for Dezod, especially at that price point and how highly reviewed they are. Wasn't looking to roll the dice when I bought these.

The exhaust piping does allow for a fair amount of movement. Perhaps you could get under there and apply a small amount of pressure to an area that will free it up enough to stop the rubbing. I`m going to try this myself . . . .

Or, I have thought about placing some kind of thin rubber (?) isolation in between the two parts that are rubbing.

The pipe will be extremely hot and will melt the rubber. I don't even have enough clearance to put anything inbetween.

In my experience, you can probably bend it a bit before it's gotten good and hot. Once it has gotten to full temp it gets a bit harder.

First thing I do is put a jack under the tranny, loosen the crossmember, mount to tranny and mount to crossmember bolts, jack up a bit to take the pressure off the mount and see if you can slide the cross member away from the pipe some.

If that doesn't get you enough, I'd take a grinder to the crossmember on that cormer.

If it's still not enough. I might tap the pipe in lightly with a ball-peen hammer.

Thanks, it looks like a lot of work to get it to fit right. I'll see if the shop can adjust it a bit more. They had to file that corner down a bit to fit...but it's still touching. Hate to have to hit it with a hammer to fit. It should just fit! So frustrating...especially for the amount of time I waited for these.
