I got an evo8 and an aftermarket 3" downpipe. it is hitting the ACD/Gearbox in a place.

what i wanted to know is how i can fix it. would hitting it with a hammer (to bend it slightly) do the trick or a blowtorch or something else would be a better way to fix it.
thankx

 

Getting a DP that fits is what would work. Id say return the one you have or sell it, then get one that fits, dont beat the **** out if it.


Btw, ive got one for sale

 

what kind of downpipe u have?

 

sounds like you have a downpipe from an '03-04 model which has a smaller transfer case. u need to resell that downpipe & look for one that is for a MY05 or newer EVO...

 

you can use a hammer...ghetto, yes but it will solve your issue...no need to buy a new one

 

^Thats what i had to do, doesn't effect the profficiency of the DP if you do it right.

 

I would have sold the one hitting and bought the correct fitting dp for acd....but a hammer certainly could do the trick

 

ahh its is a JDM spec car, and when i got the DP i told them to send me the proper one. its not hitting badly just a light tap i think. but still would like to fix the problem.

thankx for the help

 

definitely fix it...it could send phantom knock counts to your ecu

which would pull timing and make your car slower

 

for sure ^ ..

mine is the same way, definately fix it

 

yep that is why i want to fix it. but i have another problem that is causing phantom knocks as well :-( as going back to the stock DP decreased it a lot but not completely there.

as a side note, when you are doing two step (with the stationary rev limiter) do you get knocks then??

 

yes

 

ahh (even running stocklike timing) not the 5s and 6s that some ppl have. hmm there goes that theory ;-)
