PM sent about PCV Pipe and Hoses.

I had a catless downpipe on for about three days and then could not stand the drone. The completely catless system without mufflers made the spool sound amazing, but I hated the drone, and the smell was not the best either.

I have a custom cat back with the stock resonator replaced with a Vibrant ultra quiet resonator, and Nameless muffler deletes. Stock downpipe with a Grimmspeed catless uppipe, the drone is significantly reduced by the Vibrant resonator, however it is annoying in 5th gear at 70mph on the highway.

Thanks! I have been lurking on the site for a little over 2 years now. Finally decided to add to this thread. Replaced my oem uppipe that I decatted about 2 years ago with a grimmspeed uppipe this morning.

Installed a new oem inlet. The old Ebay silicone inlet lasted less than 20,000 miles before it split. Also installed a new pcv hose assembly while the inlet was off.
