Last weekend I installed a complete Roadster sport combo. Header, Helmholtz midpipe and the RoadsterSport exhaust. I also installed a new serpentine belt and new motor mounts while I was in there but they're all good.
So, I'm done, it sounds great and the car is running very, very nicely. However, there is definitely a rattle so I went back under and this is what I found
In order to get the cover plates back on under the car, I had to lift the mid pipe up so high the hanger is basically useless as the upper hanger is freely banging into the pipe and the pipe is not really hanging from it. It's hard to tell from this picture but the rubber hanger is actually rotated backwards (the lower end it towards the rear of the car) Also, the midpipe is only about 1/4" off the coverplate that is below it so it's not like I can lower it much.
Even worse, the end of the midpipe that is right off the header is maybe a 1/16 of an inch off the cover plate below it and is already rubbing.
This is a look down stream from the midpipe hanger to give an idea of what it looks like. It was hanging REALLY low before and this car is already low enough. I was worried I was going to rip it off it I went over a speed bump.
The muffler hangers seem fine. This is the passenger side, front. I was going to upload the rear hanger also but it looks like I'm limited to 5 pics. The drivers side looks the same.
This is a picture upstream from the muffler. The thing that looks like a scuff on the curve is actually mud. I parked in the some grass one evening and that was the result.
The next day I went under the car and lifted the midpipe again to get it out of the dirt. I know people say the midpipe hangs low, but with the front of the midpipe maybe 1/16" off the the cover plate below it, if I drop it down, it's going to be ground down in no time.
Did I miss something? The install went really well (took about 9 hours for the entire shooting match) so I can't see what went wrong but something is not fitting.
Any suggestions on what to do or what I missed to fix the interference issues would be greatly appreciated!
