So, I had the MRT H PIPE put on about 2 weeks ago and there was a ticking noise, with both the mechanic and MRT told me was probably pipe noise. Of course they never actually took a ride in the car to hear how loud it was. Regardless, I took it to a muffler shop today just to have them test for a leak and see if they could fix it, and they said there is a 'wisp' coming from the exhaust manifold on the left (left if you were sitting in / standing behind the car. They tightened things as tight as they could and the leak is still there as bad as ever, so my question is what do I do next? The guy at the muffler shop said perhaps I had a cracked exhaust manifold, but I had absolutely zero problems before the MRT Pipe. I'm not quite sure what to do, I remmeber someone saying they had the same problem with the Magnaflow pipe and had to use bolts without stops or something, but I can't find that thread. Any ideas? Im a mechanical retard (literally) so any help is appreciated. Thanks!
