i installed my slp exhaust today and after i was done i took it for a test drive. everything seemed fine untill i floored it. there is a high pitched noise. me and my friend checked all the clamps and were the exhaust bolts on to the cat. it still makes the noise. cant here it when i rev it so it is hard to diagnose the problem. we cant feel any air coming from anywhere either besides the tailpipes. anyone else experience this. by the way slp sounds amazing and it is definitly not to loud.

I know a kid who actually installed his muffler on backwards... (inlets/outlets) Which, IIRC, made a whistling noise. Don't ask how he managed to get it on backwards, but I guess it's something to check just in case. lol

There could be minor air leaks. Have you considered just taking it to a shop to get the joints welded to see if that solved the problem?

How can you put the muffler on backwards? Does it even fit that way?

Could have been something beside a bolt on SLP kit.

pretty positive but the exhaust might of changed the tone of the intake and make it whisp more :confused: as long as there is no leaks i guess the high pitched noise doesnt matter
