Hi guys so I rlly need help with this minor issue I am running a tomei turbo outlet to a no name/i wanna say maybe ebay downpipe I found it in my project car and it seemed to fit fine to a megan racing test pipe to an hks catback hi power. Now my problem is my exhaust and even test pipe dont line up properly and they dont go by the hangers?! im so confused right now maybe my downpipe is wrong? I have attached pictures if anyone can help me with this issue that would be great I used metal zip ties to hold the resonator pipe to an exhaust bushing for now it doesnt work that well and the resonator pipe hits my rear sway bar. I was driving open downpipe prior to this or open testpipe to be more precise.

If your wondering why my wideband AEM o2 sensor is cut is because they had to warranty me a new one due to mine failing obviously and you have to cut it and show them you did for the warranty to work.

Update guys I fixed it must have been something caught uo because this morning I moved the muffler to the left while supporting it lightly with my jack and that seemed to help position it correctly into that little hole into the seay bar where it goes up for your exhaust. im really satisfied overall.

Thanks man yeah like its easy once you figure it out to be honest the rear sway bar has like a dimple or an inwards u shape where the exhaust sits its hard to miss and I used a hose clamp for the rear catback temporarily because I do not have a hanger but it works perfect and sounds great! The car feels way better with the catback system on it versus just an open downpipe basically.
