I have an exhaust question

[99'EclipseGS]

So I bought an cat back exhaust system off eBay. 4.5 inch tip 2.5 inch piping. Now it sounds alright the only thing is that the hangers from the exhaust weren't made too properly. I had my mechanic put it on, and he used the right rubber pieces or whatever but my exhaust is rattling and I think either from the axle or the pan or whatever where my spare tire is. Any suggestions? I tried moving it, switching up rubber holders, getting different hangers, idk what to do And it's really annoying

You could try taking it to an exhaust shop and have them look at it, sometimes they have little tricks to make stuff work and look better. Or they might be able to cut and reweld the hangers in different locations so it all flows smoothly under the car and doesnt hit anything.

Yes take it to an exhaust shop. I put an ebay exhaust on a freinds EVO 8 and when I put it on I told him the down pipe was awful clost to the transmission (about 1/2 inch) and that he need to keep an eye on it to make sure it was not rubing. Well he did not check it, now he has a small hole in the case of his transmission! You need to find where its rubbing and fix it now before you have problems later.
