Sammo 2544 Report post Posted July 21, 2020 Coming up on my E46 to-do list is the exhaust - M54B30 - all stock currently with the 'golf tee mod'. Dual pipes all the way I think. Goal is more volume and a great tone, especially at WOT / higher RPM. Little performance would be nice but not expecting much at all there. I impulse bought a Supersprint 'slip on' rear muffler on FB marketplace this weekend after a few wines, heard good things about their stuff for BMW. Will need to get that fitted obviously, but from there I'm expecting a few other tweaks needed to get the volume i'm after: Cat delete? Resonator delete? X-Pipe? Any recommendations for exhaust shops in Auckland? The best approach I guess is get the muffler on and listen to it and talk to them about my goals?

zero 1162 Report post Posted July 21, 2020 Gutting the cats is worth doing. I've heard alot of exhaust setups on a m52b28 and the cheap redline stainless mufflers sounded better than the supersprints and remuses which suprised me. 1 Quote Share this post Link to post Share on other sites

Gutting vs deleting = less potential WOF issues? A bit of extra volume and flow I would think too? Original plan was to just get a cheap straight through stainless muffler but this one came up and jumped on it. Videos online (for what those are worth) with the supersprint sound good, albeit a little quiet, hence thinking I'll need a little more done. Quote Share this post Link to post Share on other sites
zero 1162 Report post Posted July 22, 2020 Yes, I would recommend gutting as opposed to deleting as the gutted cat then acts as a partial resonator to remove unwanted tinny noises. Also I think it looks cleaner. And use headers from I think the s52. 1 Quote Share this post Link to post Share on other sites
M M 250 Report post Posted July 22, 2020 (edited) If it's anything like my E36 M52B28 it will be plenty loud with just the muffler replacement. I got a twin pipe perforated straight through muffler from Chase to replace the rear one on mine and it sounds fantastic. If you just want noise I doubt you'll need to do anything further. I do like Zero's suggestion about gutting the cats though, might look into doing that. Edited July 22, 2020 by M M 1 Quote Share this post Link to post Share on other sites
