KyleK 1 Report post Posted January 4, 2015 Hi, I'm a new owner of E46 320i I really like the sound of the straight 6, and i want it to be a little louder and make it sound more alive. so far from research, i have seen a few people talk about muffler delete and straight piping. Is this legal ? and if so do you need cert for it ? if its not legal, where would i be able to get a muffler to make it sound better ? Thanks guys Quote Share this post Link to post Share on other sites

No cert necessary, however it could fail the wof for a noisey exhaust (the limits are a bit down the page), which I'm sure a straight pipe might cause you a bit of trouble with! There are some kits out there, check E46fanatics for people who have bought decent setups but they do run you quite a bit of cash, especially trying to get them over here etc etc Personally I've kept mine standard, between the automatic gearbox and its gutless moments I think the rasp can on the end of it does just fine for those moments when I want to be heard, but if you do go ahead and do it, I'm keen to see how it works out!

Hey I visited a local exhaust shop / garage today and asked the mechanic about muffler delete. He said if i get rid of the rear muffler it will sound like a tractor and cops will green sticker it, which means I will need to put it back to standard muffler and get a noise cert as well which is $250... Bugger.. but I don't want to get a green sticker on my car haha. He quoted me around $280 for a new muffler installed that will make it a little noiser than it is stock. He said it is harder as it is twin pipe exhaust. I am considering either spending my cash on muffler or saving up for after market rims later on in the year. I am only a student so I only have a certain budget :/ But yeah, if i do get the muffler done I will post about it Cheers Quote Share this post Link to post Share on other sites
