Attachment 79632



I think I am going to change out the stock resonator for an Xpipe and then have the cutouts as a dump like bcredliner. I HATE not having my exhaust come out of some sort of tip, but I would like a bit more volume at times so having the cutouts after the X-pipe as dumps would accomplish that. And maybe then I'd actually use the cutouts every now and then.



Here's what it sounds like currently:



X5 exhausts



The grey 4.4 N62 is running Corsa mufflers.



Dinan exhaust w/ cutouts



I have long since fixed the exhaust leak shown in the video.

You have an N62 4.8iS right? Will you go with a 2.5 inch x-pipe?

Not sure if this helps, but this dude has 4.4i with 4.6is exhaust system and used 2.5.

Hey thats me! :wavey:

The 4.4i uses 2.25'' stock but I used a 2.5inch Xpipe, welded on with 2.25'' to 2.5inch adapters because a 2.25'' X pipe was hard to find around here.
