    rv6 downpipe exhaust leak?

    I installed the catted rv6 downpipe and invidia q300. I also got the car tuned by Steve over at eztunes. It took a while for the tuning process, mostly because I had to stop halfway through and figure out how to get it to pass inspection (I live in NY). After adjusting the defoueler and flashing the ECU to stock, I finally got it to pass. Now I'm running the tune from Steve and I'm not sure if this is normal noise for the downpipe to make or if I have an exhaust leak?

    Does it do it all the time or just on a cold start?

    Sorry I didn't clarify that. It's only on cold start. And it goes away after about 30 seconds.

    Mine does the same thing. I think if it was a leak it would make the sound all the time.

    Thats what I was reading. That allot of these aftermarket downpipes make noise on cold starts. Just wasn't sure if that's what the noise should sound like? I was also under the impression that exhaust leaks are more noticeable during cold starts. That once the engine and exhaust warms up the noise does down.

    Yea I dunno about all that, but the sound yours makes is the same mine makes. Last time I had an exhaust leak it made my car sound like a diesel truck and was more noticeable when it was warm.

    Sounds just like my car does on first start up after sitting for awhile. Normal as far as I know.

    I gave up tightening my exhaust all the time. Once the metal heats up and expands, the gap for the exhaust leak is gone. Normally 15-20 seconds. Think my downpipe is good, but the slip on style mid pipe is the culprit.

    Thanks for all the input guys. I guess I'll just leave it alone then.
