Did this increase the drone inside the cabin? I have a jb4 what do I have to do to get the CEL off? Do you know if I can pass NyS inspection with the jb4 and this fatness down pipe?

Little to no increase in drone, the main change occurred when I changed the exhaust. The DP had little to no effect on exhaust volume. As far as the installation procedure is concerned, I did not do the install myself but I'm sure you can find a link for the install on the forum and any additional questions you might have I can put you I touch with my installer. As far as emissions inspection is concerned, that you would again have to refer to the forum because my car was brand new when I had the DP installed and didn't have to have the car inspected while it was installed. You need the DP to run stage 2 on the JB4 which is where you really start to see gains. N54tech.com would have plenty of suggestions about what to do for emissions.

Hope you realize that this exact pipe "VRSF" is sold new 399$ (MSRP price) from X-ph.com. Also there is a "better" ER downpipe new for 505$ (on sales) with flexible / 4" tubing and mounting points...

Good luck with that sale and for sure a downpipe help to open up the N55 (paired with Jb4) quite a bit ! |

It certainly did, I had a fully modded N55 with a meisterschaft gts exhaust along with cp, meth injection, air intake, etc and the DP made one of the most significant differences because of the increased mapping available with the JB4 once the DP was added.
