I wanted to buy the Greddy Evo 2 exhaust but i read that a couple people had problems with part of the bumper melting!!! Does anyone else have or had problems with this because this is going to determine wheter i go with the greddy's or the comptech

 

have had my setup for about a month. no problems about melting. only problem i have is carbon build up above the exhaust tip cause im catless. but its never a problem since my car is almost always clean, except now...

 

^ Thats no good cause i have SSM and that would be really noticeable but like you said that just might be from you running no cats but they run hotter too w/o cats right? i bet thats SUPER loud!!!!

 

I've had mine on for about 4 months now (seems longer) and my bumper is still fine. And I have the A-Spec kit too.

 

It must be the position in which the exhaust exists, or the position of the pipe itself. If too short the hot gases make contact with the bumper and it melts away. Same as I've seen with the extremely hot exhaust gases from the RX7 rotary. I've never had a problem with our modifed turbo, but many have had the bumper melt from positioning the exit area incorrectly.

From the Greddy pictures it looks like not only is the pipe very close to the bumper as the black plastic surround is removed, it should be extended farther and cut on more of an angle to reduce the flow up to the bumper area.

The car sound like a bumble bee in flight.

 

it takes many many miles for it to build up. i always keep a spray bottle with car wash soap for that and also bird shit and a bottle of spray detail
