Hey guys sorry to disappoint by not posting the usual “which oil or oil filter should I use” thread but I’m trying to get my exhaust bolted up on the Z.
Headers fit fine-just trying to get the pipe between the x-pipe to the factory npp mufflers in place. Everything was bought from the same place(tps) so they should work together although it’s easier said than done especially trying to do it on jack stands. I had everything loosely clamped after the headers but my issue is the pipe after the x-pipe seems too long to fit with the stock npp system. Snapped a few pics to make sure I’ve got it all situated correctly.
Its a pain in the ***, but you will definitely need another set of hands to help guide and move into place. I am going to be welding in some v-bands to avoid this slip fit crap in the future.

exhaust is pretty straight forward so I don’t get what the issue is unless the parts aren’t correct which the company has already insisted they are.
Should I be able to get everything on with the stock npp mufflers completely in place?
Have you ensured each of the slip joints are pushed in as far as they can go? They are likely tight, but if each one isn’t fully seated that could add quite a bit of length...something small and simple that could make the install darn near impossible.

yes sir. From eyeballing it the pipe appears to be 3-4 inches too long which has me questioning if it’s really the correct part. Hopefully I’ll be able to figure something out. Stupid crap like this has me tired of messing with cars.
I have experienced the exact same thing with a header xpipe combo I purchased recently. Albiet on my 2010 grand sport but what i ended up having to do was cut a few inches off the pipes going from the xpipe to the axel back and that gave just enough room and them I lengthened the slit cut in the pipe so they can conform down onto the other pipe, it wasnt an easy install in anyway and I had access to a lift while doing it. It was such a struggle I ended up receiving a partial refund for my trouble my next plan is to weld in V-Bands to get rid of some of the slip fit issues. Best of luck to you.

i figured that was the next step. Sounds simple when I think about it in my head.
Next time I’ll be sure to only purchase from known brands/vendors instead of a fairly new company with subpar customer service.
Thanks for the input!
