What y pipe are you going with? Is the rest of the exhaust stock?

Good job, Brad! Glad to see you doing something with your car again, and particularly a worthy mod like this.
(psst: motor mounts, motor mounts, motor mounts, LOL)

Just those Y pipes you see on Ebay more than likely (in the $150 range), and I have the Top Speed Y back exhaust.
As far as fuel smell, noticed a bit, not much TBH, I was initially overwhelmed by the burning ATF mix that I slathered on the bolts.
The exhaust smell seems to be something I could live with since I rarely am idling in stopped traffic.

I rarely notice the "raw fuel" smell with the cats being gone when I'm in the car, but it's very noticeable to me when I'm outside the car especially on a cold start. I kinda like it though so doesn't bother me one bit lol.

Ah makes sense. How do you plan on transitioning from the 3" outlet on the ebay Y pipe to your Top Speed Y?

ahh, the good 'ol days of California smog testing....I remember keeping my stock set of cats and swapping them in every other year for the smog tests when I was running BERK HFC's in my M35. What also helped with the fuel smell was when I ran the Motordyne xyz pipe (ypipe) + HFC module. I'm not sure if MD makes the xyz pipe for the g37 - haven't visited the site or talked with Tony in a long while, but that would be ideal.

As far as the raw fuel, it's not overwhelming, at least standing behind the car in the garage (standing outside). I doubt I'd want to be backing into my garage on a regular basis though. And yes, the fuel odor is to be expected w/ test pipes since there's no catalyst in the exhaust stream to break down most of the emissions.
