small exhaust leak
installed a challenge sport x pipe couple weeks ago and sounds good but a little muddy like i have a leak or something vibrating under there and touching the heat shield. got the car up in the air today to look and formed the heat shield so not any touching parts just in case. i have a leak at the fitting between the resonators and the rear axle section. i can put my hand by it and feel it on both sides right where the clamp comes closed and there is a little gap. the stock axle back has a little crimp in it at these points maybe from overtightening from the factory. any idea how to seal this leak. just tried to use some high temp sealant in the area its leaking and am letting it set up. dont really want to weld these together but want it to sound correct.
