okay, i was on the freeway, boostin' normally. I decided to slow down so i left off the gas. while coasting down in 6th gear, i hear a few clanks...as if something popped off, and then a loud exhaust growl. So i knew one of the exhaust pipes popped off. took it to the shop and they told me that its such a tight fit, that one of the pipes is touching the chasis. they put the clamp and pipe back on and everything ran smoothly. i notice now there is a slight rattle. i tried to find where it came from. I noticed that its where the exhaust pipe "downpipe 1" (P/N 21185) meets "downpipe2" (P/N 21186). I guess its the V clamp that sittin right against the chasis which causes the rattle and I feel that popped off earlier on the freeway. okay, my question is, would there be a way to loosen that clamp and turn it so fat part of the v clamp isn't facing the chassis? currently, it looks as though the fat part of the v clamp is touching the chasis, but if i were to turn it, i think there would be enough clearance so under hard acceleration or shifting, the pipes won't touch the chassis. how would i go about approaching it? from underneath or up atop under the hood? sorrry, not really mechanically inclined. does anyone else have this problem? would my car being low (& scraping pipes over speed bumps) affect this problem also?

 

no scraping wouldnt matter.

But yes if some of the V-clamps arnt put on in the right direction they will touch other parts. What I would do is try to get it from up top by removing the intake pipe the one with the BOV. You should be able to remove the bolt from the V-clamp and open it up and just turn it around.

 

Thats hard to get to....You wont be able to hit it from the top very well, if anything you need to disconnect the exhaust, downpipe 2 from downpipe 3 and work your way up to that from underneath. If you position the clamps correctly you wont get rubbing, I never have had any rubbing/rattling with mine. Id take it back to the shop if I were you, I think its more than you want to mess with if your not mechanically inclined.

 

+1

Best way to fix this is loosen all the clamps and re-adjust the downpipe...

 

yeah, i was thinkin' of doing it myself 'cuz i'm tired of going to the shop (3rd time already)...but then again, its because of their install that makes me go back. i know its gonna pop off soon again. i should just wait til my day off (friday) to take it down..until then, i guess i gotta drive conservatively. thanks guys. just wanted to be sure that the clamp was able to move around...thought it had to be set in a certain position on the pipe.

 

I seem to get it easily from up top because I recently messed with it when I installed the overboost fix pipe
