Since this is not a performance mod I'll post it here. I wanted an F30 328i look so I purchased a galvanized Y-pipe, two (6" long x 2.5" diameter, rolled, tips) from the local Holley store. FYI: Bowling Green KY is hot rod central. Home of Holley Performance, the Corvette Assembly Plant, NCM, NCMP, LS fest, and much more :) ... But I digress... I sprayed high temp matte paint on the ID of the tips, MIG welded all three components together (1/2" offset, dual tips), drilled 1/8" drain holes, and trimmed the valance a bit. Then I took the completed tailpipe assembly to my local exhaust shop (Mark Muffler) where they cut off the pipe from the OEM muffler, fab'd up a connection pipe, welded the assembly that I brought them, sandblasted the connection pipe and y-pipe, welded on a hanger that connected the tailpipe to the rear OEM exhaust hanger bracket, and then coated the connection pipe and y-pipe with more high temp matte paint for corrosion protection.

I did this because the factory tailpipe looked weak AF, and paying $500+ for a cat-back, that yielded no power, was absurd. $100 for parts, 2 hours of personal labor, and $100 for paid labor. Great deal and look IMO. Plus, I haven't found an aftermarket exhaust that replicates this look. The ZZP DP yields the flow I need for the BNR tune on 20+psi, and the Holley tips give it the look that it needs for a 15.0, 1/4mile. No sound compromised :)

Have you any pictures of the fabrication? Or maybe a shot from underneath? Loookin' Goood Lucy!

Like, as they were installing, step-by-step? That would be a negative sir... I fab'd it up a couple weeks ago for the COTM thread. I can take a pic of the finished setup though. It's hella simple. The only reason I didn't finish it up completely is because I do not own a pipe bender, nor do I know how to use one. The tailpipe welding was completed at work as a "gov't job" because I do not own a MIG welder either lol.

Yep. No jack needed. I'm already turned in, for sleep, for work tonight though. As soon as I get off tomorrow morning, I'll snap a pic. Not much to look at though. Stock muffler with some snazziest of snazzy tips. :) Tried to limit the ghetto fab to a minimium. Absolutely, minimal sound change, which is exactly what I was shooting for. Slow cars need to be quiet IMO.

I wanted to keep it simple and quiet. My 5th gen is slow compared to all my local buddy's LS powered machines and Coyotes. HPtuned Borla catless longtubes, bolted up to factory resonators and mufflers, barely announces an extra 50whp, and gladly so. I'm not trying to give off any power performance increase but the Cruze's tailpipe is pretty much "non-existent". I had to make a change for the Cruze
