racerx Posted May 9, 2017 Report Share Posted May 9, 2017 Jalex, last time I'm going to ask, have you gone to other z web sites to see if this is normal. The other day, a new z,went by me on the road and I can tell it had an aftermarket muffler, and I heard it popping. 1 Quote Link to comment
jalexquijano Posted May 9, 2017 Author Report Share Posted May 9, 2017 some say its normal, other say i should have an exhaust leak somewhere and i should also use PERMATEX ULTRA COPPER RTV together with the gaskets. Quote Link to comment
racerx Posted May 9, 2017 Report Share Posted May 9, 2017 Maybe u should put the old exhaust back and see. I don't think you will get an answer u want to hear. A lot of times, you have yo diagnose yourself. Quote Link to comment
KoHeartsGPA Posted May 9, 2017 Report Share Posted May 9, 2017 some say its normal, other say i should have an exhaust leak somewhere and i should also use PERMATEX ULTRA COPPER RTV together with the gaskets. It's fairly easy to find an exhaust leak besides the visual....have someone cover the exhaust hole while you get under and listen for the leak.... 2 Quote Link to comment

You know, I think to get past this you should replace all the gaskets and use whatever sealer you choose. Seems like this is the only thing that will satisfy you. Come back and let us know how well this worked. 3 Quote Link to comment
jalexquijano Posted May 11, 2017 Author Report Share Posted May 11, 2017 Found a leak at the manifold to downpipe section. Ill have to remove the downpipe, clean the surface and install a new gasket 1 Quote Link to comment

distributorguy Posted May 11, 2017 Report Share Posted May 11, 2017 Simple diagnostics turned into another typical multi-paged debate. :rofl: The "towel plugging the tailpipe" trick apparently worked. 2 Quote Link to comment
jalexquijano Posted May 11, 2017 Author Report Share Posted May 11, 2017 Well what the mechanic did was to put a garde hose and listen to the leak. I hope the shop that installed the msa premium exhaust did not damaged any of the studs in tha manifold. I did notice that when removing the stock downpipebhe had to use the solder gun to hear that area as the nuts did not turn. Quote Link to comment
racerx Posted May 11, 2017 Report Share Posted May 11, 2017 oh crap....at the same time, we don't know if that's the culprit that cause the popping noise, nez pas? 2 Quote Link to comment

distributorguy Posted May 11, 2017 Report Share Posted May 11, 2017 More mindless debate... Please report back after fixing the exhaust leak Jalex. 1 Quote Link to comment
Ranman72 Posted May 12, 2017 Report Share Posted May 12, 2017 More mindless debate... Please report back after fixing the exhaust leak Jalex. after having your exhaust leak fixed since you dont seem to be the mechanic as was implied Quote Link to comment
jalexquijano Posted May 13, 2017 Author Report Share Posted May 13, 2017 Mechanic changed the manifold to downpipe gasket. Deceleration popping at tailpipe still present. What a pitty!!! I guess the only way is to revert to the original stock exhaust system that had a resonator and normal muffler Quote Link to comment
datzenmike Posted May 13, 2017 Report Share Posted May 13, 2017 Just replace the muffler. Pipes are pipes. Quote Link to comment
jalexquijano Posted May 13, 2017 Author Report Share Posted May 13, 2017 the MSA kit brings a turbo muffler. The one i had was a dynomax muffler but had a resonator in the middle of the pipe. Quote Link to comment
datzenmike Posted May 14, 2017 Report Share Posted May 14, 2017 Well you should be able to cut out a space for the resonator. If you look, the resonator is straight through pipe. You could try adding the resonator in line and see if that tones the popping down. Finally you could put the dynomax back on. 1 Quote Link to comment
jalexquijano Posted May 14, 2017 Author Report Share Posted May 14, 2017 ill keep tracing for leaks to see if there are any before taming the popping Quote Link to comment
Ranman72 Posted May 14, 2017 Report Share Posted May 14, 2017 dynomax are great mufflers turbo mufflers suck 1 Quote Link to comment
