i've had experience with them. they're not bad for what they do. basically keep the car stock until its time to run somebody then open the cut-off. serves its purpose. usually its right after the downpipes but isn't the exhaust on the n54 setup with two pipes? so u would need two to make it work right.

Do they leak ??

TurboSid · 03-22-2009, 09:57 AM

no not if they are welded on. thats why id be reluctant to doing it to the stock exhaust (unless you don't care)

if i was to do it. i would but aftermarket downpipes and have the exhaust cutout modified to those if possible. so u can go back to stock if u wish.

www.quicktimeperformance.com also makes cutouts
