The rasp is absolutely no problem for me. I actually didn't mind the rasp on the E46...

Thanks Again,

My friend Jerome (before he sold his M3) had an 08 E92 with the secondary cats pulled out, and I was not a fan of the sound at all. Much less refined and way too raspy. Make sure you listen to a car with this setup first before you do it to yours. Maybe in conjunction with a rear section mod it would sounds better.

Dinan intake does not void your warranty.

Not true, even Dinan can technically "void" warranty, they are not exempt.

However, most dealers do not care.

Very interesting suggestion. I suppose if I went to a Dinan-certified dealer and got an intake installed then that dealer would probably have to honor the warranty if their work led to a problem. I will definitely research this angle - thanks!

Mike,

I hope you're doing well! Thanks very much for the feedback - I appreciate it. I definitely won't do anything to the exhaust without listening to it first. I'm still leaning towards the OEM Exhaust Mod (non-perforated) based on my research. Thanks again.

Jeremy

Ancient thread revival...has anyone ever tried removing the sound insulation panels numbered 3 and 6 in the diagram below? If so, how much effort was involved? I've been desiring more engine/induction (not exhaust) sound in the cabin, and removal of these may provide a bit of increase.

The Goke carbon plenum adds a lot of induction noise into the cabin (a la E46 CSL) with a WOT but is refined like stock when cruising.

The induction noise is very pleasant and changes with revs - one can almost use the throttle to play a tune!

I'm sure the Goeke plenum does sound a bit nicer, but at that price I'd want a full carbon plenum rather than just the top half. I'm sure that if/when I get a carbon plenum, I'll still want more. It looks removing any of these panels may be a fair bit of work though, and I was hoping someone had an idea of just how much.
