If anyone can help, please do. I just put on the MMW headers today and i have an exhaust leak where the header connect to the s-pipe. It seems like the flange is too big but i dont know. Anyone know what I can do to fix it?

Plus i have a really loud and raspy car and my friends said they could hear me all the way down the street. I have the TRD axel back and thats it. So if i get a 22' or 30' resonator welded into the stock mid pipe then that should take away rasp and quite my car down right?

Any suggestions would be greatly appreciated, otherwise i am going to go to a muffler shop and have them fix it and put in a resonater.

 

i recommend buying the stock exhaust gasket brand new from a toyota dealer, the only problem that i ran to is that i had to trim it down quite a bit.. so it can fit really tight, other than that i have no exhaust leaks.

i have CC full exhaust, high flow cat, 14" resonator and i have no rasp and my car is ALOT quieter than my old alphawerks and CC s-pipe set up.

 

Its not the gasket. Its the part that connects the header to the s-pipe piece. I can feel the hot air coming out from it. Thats where the clicking noise is coming from too.

help help please

 

Yeah i ment to say the donut gasket ! thats exactly what you are talking about ?

 

ummm there is a slight slight leak from there but its mostly from the header to the s-pipe piece that right underneath. for some reason it just wont seal.

 

so you're saying that the MMW header has fitment issues with the MMW s-pipe? (gasp) That's not good.

 

Yea, cus it comes with 2 parts. The header and then the part that turns into the s-pipe. Well there is a flange that connects the two. Well me and my friend tried like 4 different times to fix it. it just wouldnt leave. My friend knows what he's doing too cuz he has a 89 E30 BMW with a Custom T4 setup. Now i have the leak and my car sounds like a rice rocket on steroids.

PLEASE HELP MONSTERMOTORWORKS!!!!!
its ur part!

 

yeah i know its' two parts! but being that they sell and ship them together they should atleast test fit them before shipment. i'm so mad cuz I don't want this to happen to mine when it finally comes in (on backorder)

 

Weapon R makes their stuff, its hit or miss with quality. I hate to tell you, but their stuff is crap.

 

There shouldnt be aby issues at all. Make sure the donut gasket is on and you tightened your bolts inside to outside.

 

wow... im guess the MMW header "IS" a hit and miss... i would have thought that they would have fixed their problems by now... yes i know they are hand made but im pretty sure they have a jig to setup the header on.. with the quality control issue they have if were them, i would be checking fitment on 100% of the headers that go out..


anyhow... i would call them... one thing about them is they do work with you on fixing the issue... on the RASP... yup.. the TRD axle back sounds like total crap with a header... a larger resonator may reduce or even kill the rasp... but im not sure it will make it any quieter...

i had a TRD axle back installed aswell and bought the MMW header... ended up re-installing the factory axle back.....

 

Yes, we do have 4 cylinders. You will have rasp.
