I just bought a Taipan XP Turbo back exhaust from Vishnu for my 05 MR. I bought it used, only about 2000 miles on it; from my brother in law (Sano) who had it on his 03 Evo. It has been on now for about three days. I have only drove it twice now with the new exhaust on. It has got me a little nervous. Right around the time the turbo begins to spool at 3000 rpm it makes a rattling noise. Not every time but often enough. Is this to be expected or do I need to hurry up and put the stock back on?

Thanks for the help!

 

im pretty sure that its the downpipe hitting the front bar. Check for clearance issues.

 

^^^ What he said, your downpipe is probably rattling against something ...
