I currently have an underground parking garage and even when taken at an angle (narrow driveway) i lightly scrape my flex pipes on my cats at stock height (08 G37S Coupe) and aftermarket wheels. I despise the current wheel gap and need to throw a set of C/O's on but am worried about getting stuck and/or wearing through my cats. Who has installed RHFC's (any brand) and could tell me if it hangs lower, or above the stock height. Thanks in advance and I hope this was the right place for this thread.

I installed Fast Intentions RHFCs on my sedan, with approximately a 1.3" drop in the front, and 1" in the rear. I saw some scrapes on the cats, but nothing too serious. The scrapes happened when I hit a pot hole in a parking lot at a very, very slow speed. You shouldn't have any issues, as the cats hang at stock height. Remember, they still have to line up with your exhaust manifold and y-pipe.

 

Thanks for the quick reply. I haven't been under this car too much (installed axle back system), do the RHFC's retain the flex pipe still? I'm guessing it will since it has the factory Y-Pipe. I wonder if I could wedge it up a bit or adjust some mounts.

 

When I did my install, for a just a little more room, I bolted the cats to the y-pipe first. Next I jacked the mid-pipe and y-pipe up before I bolted them together.
