i just installed buddy club spec 3 ctr exhaust on my civic. it makes a horrible sharp rattling noise at 3500 rpm. my friend suggested it might be the metal springs used to connect the pieces rattling against the pipe (because the pipe shakes badly). he said i should get exhaust insulator over the connecting areas...i will probably take it to meineke tomorrow but im really worried about if it's been damaging the exhaust/car driving with this fault...

can anyone offer any help or advice?
