Tomei why you fail meee! :'(
 

I recently bought tomei uel headers for my car because I read only good things about it. When I installed my ark exhaust I decided to do the headers as well and the fitment was off! One side fits in perfect but then the other side won't go in. It's just one bolt hole thats off by a little, and the overpipe won't attach as well :/ anyone had the same issue?

who did you buy the header from, did you contact them yet?

This! I haven't heard of a single fitment issue with the tomei.

Myjdmparts from amazon. I took pictures but I need to resize them to post. Kinda having trouble with my phone

first time I heard of fitment issues, pics? and please contact ur dealer

Idk if you guys can see it in this vid

Other side is on but this side. As you can see one hole is off

Are all the nuts loose when you try to install it? Sometimes the header needs convinced it want to go on and all the nuts either need to be off, or extremely loose.

Nuts aren't on bro. It needs to go in before I put nuts on. That's the problem

Did you try installing the header first? Remember all 4 bolts should be inserted at the same time.

That's what she said.


On serious note, there's a specific way to torque these so they fit nicely, starting on the passenger side. Your issue looks pretty bad since you can't even fit it on. Like others have said, contact the vendor you bought it from. That should be a warranty item.

Did you undo the overpipe to front pipe connection??

Hm maybe I should start from the passage side. I'll see but I don't think it'll make a difference .

No but I'll try that too

That's your problem. Undo the overpipe to front pipe connection (use PB Blaster or wd-40 and let it sit for at least a few minutes before trying) after that get everything lined up with bolts hand tight, then start tightening at the header to engine bolts. Then tighten the overpipe to frontpipe. Then torque everything in that same order. If it still doesn't line up, you have a fitment issue.

Never seen fitment issues on a Tomei... The flange isn't bent or anything is it? Also; I'd strongly reccomend disconnecting everything from the header itself, and then installing the header. No over\downpipe etc, just the header alone going on, and then connect everything else.

When you say other side is on makes me think you pushed in one side completely, you do know you should try and push in both sides at the same time, making the studs come through evenly?

I feel like you are doing something incorrectly here. I bought my UEL tomei from myjdmparts on Amazon two weeks ago, and had infamous performance install it last week. They had no fitment issues, and the car runs and sounds great.

Or you can go to a muffler shop for installation.

people who are saying I had no issues when I bought my Tomei aren't winning

people who are suggesting the dude takes 10 minutes to undo all exhaust components before attempting the header are winning

I did both. What now?

you sir broke my equation :(

Did you loosen the joint and try to spread it apart or push it together to make it fit?

I took a hammer and tap it a couple times till it went in. End of story haha

P.s I tried everything and every suggestion

Ok, well that is the correct method, so congratulations.


Make sure you re-torque in a few days.

Use a blowtorch, they solve every problem :)

So is anyone running tomei uel with ark grip exhaust? It's obnoxiously loud like a muscle car.. I think something is wrong with the header :/

You're helpless

Your helpful

You do realize that without a cat on the header, it will make the car louder...

Yea I know but I didn't know it would be muscle car loud with popping noises. I'll take it to a shop and let them look at it

It's not a manufacturing defect. That's the way it's supposed to sound.

You probably now have an exhaust leak

Thats what I'm assuming not a defect

do you have any other exhaust bits? did you re-use any gaskets?

i'm with that sexy stud of a @Sportsguy83 in thinking you have an exhaust leak somewhere.

<3 the big red wrench

Oh and a headerback system is generally stupidly loud

oh so gloriously loud :thumbup:
