Leak, maybe more then one, help!?
I got a brullen turbo back installed at my dealer, who is 1.5 hours away, so not easy to just go see him about this.. so i need your help with some strange noises i am hearing. My setup..
3" all the way, 1 cat.. catless up-uppipe with flex.
I have narrowed the sounds to the following, could u let me know what sounds u get and dont get..
1. under acceleration (pretty hard) , i hear air rushing through somewhere,.
2. full throttle , after a couple seconds and lasts till i ease off the accelerator, I hear screeching , maybe vibration like rubbing of metal? possibly heat sheats?
3. I hear a faint wistle, almost there constant.. more when i am pressing the gas. 4. when i loooked under the hood and pulled the throttle cable quite hard, when i let go a clunk, ting kind of sound..
I'm so confused as to whats normal or not, or where to look first..oh and the up-upipe was fitted with new gaskets and bolts..so they dont think its the up-upipe

Well I can't help you with the noises you are describing because I think I'd need to have a better idea of where your ear is hearing them coming from.
But I can tell you that an exhaust leak doesn't sound like any of those things. An exhaust leak sounds like a junked muscle car/jack hammer, etc. depending on how bad. It can go from a thup-thup-thup-thup to a bom-bom-bom-bom (heheh) but more far more pronounced than a proper after market exhaust rumble, especially at speed.

I agree, I had this problem on my old mitsu Eclipse, I would hear those sounds under the same conditions you would. Problem was, I used to go through header and downpipe gaskets like you would not believe. The bolts would come loose after high rev driving and consequently the gaskets would blow. It was a nightmare. My suggestion is to check all the bolts and gaskets and make sure they are intact/tight. The eclipse headers were made by Kamikaze by the way.
