    I am installing headers in a few weeks and I plan to cut the muffler off as well... maybe the resonator too but after I see how it is with headers and muffler delete. Anyone have experience driving with headers and muffler delete? How F***ed is it really when driving in a quiet town at night or...

    Hi I have some stainless steel headers (Ebay :p) coming in the mail and once they get here I plan to either ceramic coat them myself (I've looked into VHT flameproof spray and exhaust wrap) or to ship them to swain to get them professionally coated. Doing it myself would save a lot of money, as...

    My car has a rear muffler delete but I still have the cats and resonator. When I lift off the gas sometimes it makes little crackling noises. I checked the DME a while ago and it has the newest BMW firmware on it (thanks BaliDawg) but could that have been modified to make these sounds? Does my...

    Don't get mad that I created another "eBay header thread." I just wanted to see what company you recommend. I have heard a lot of positive from blackhorse-racing. But then again, there are a lot of eBay headers out there. Here are all the 325/330 headers I found that have been bought more than...

    Been debating about exhausts for about 3 months. Was set on the eissenmann but due to the £250 shipping on top of the exhaust to uk. I thought I would try scorpion as was next day delivery and half the cost. Searched for hours but there is very little about these exhausts online. Got the...

    Hey, I am currently chain fixing both rear wheel bearing/hubs, cab, and guibo in my car. I have changed the right side so far but on the left, I stripped a bolt in the diff flange. I need to drop the exhaust to cut and get it out, as well as for the csb and guibo. What tools do I need to cut...

    I seem to have looked everywhere but cannot seem to find out how much louder a Eisenmann race muffler is than stock. does any one have a decent video without headers on. I'm looking for a deep sounding exhaust, every one rates the UUC Corsa but seems abit to raspy to me any advice will be...

    I know what you're going to say, there are so many threads about droning and exhaust droning in general. I cannot find one that is just spot on helpful!!!!! I've looked through countless exhaust threads trying to find a solution to my exhaust droning. This is my first car, and i'm 18 so of...

    I swapped out my stock muffler for a magnaflow muffler a while ago, in the last few days I have had a lot more exhaust pops, could this be because of an exhaust leak? Any ideas or some insight would be nice.

    Hello, Not sure if there is another place this should be posted, if there is please let me know. Our 2001 M3 vert came with what looks like a Top Speed Pro 1 exhaust. I research it and found it on the website BMW E46 M3 Coupe Convertible 01-06 Rear Section RACE Version Exhaust System. This...

    Unfortunately the day has come when my cats have gone bad. From the looking that I've done, it's quite expensive to get these replaced. I was thinking a potentially cheaper solution would be to replace the headers with the Active Autowerke headers, as well as some after market catalytic...

    I've been surfing on the internet and tried to see how it sounds like when an E46 does a muffler delete. I have a 2003 318i N42B20 engine, here in Indonesia (southeast asia), the 318i is quite popular since there are only 3 model variants sold: 318i, 325i, 330i. When I first bought the car, it...

    I recently purchased a vibrant 1148 muffler for my e46 and hadn’t realized that the stock e46 has 2 pipes coming from the resonator to muffler inlet, and my new muffler has just one. The new vibrant muffler has a single 2.5” inlet while stock has 2 2”. I’ll be needing a Y-pipe installed of...

    I'm considering deleting my second resonator on my 330Ci, which is otherwise completely stock. Is this a terrible idea? Will it sound raspy and unbalanced? I'm hoping for a deeper more grumbly sound but nothing too obnoxious. Anyone who's done it, what differences have you noticed? Also, this...

    Is there any difference between 325 and 330 exhaust sound or throughput? I know the 330 has the vacuum flap. I swapped a zhp exhaust into my vert and have the old 330 exhaust in my yard. I was thinking of putting it into my 325 touring (which is slated for a 330 swap at some point), but not if...

    Hey guys I'm relatively new to the BMW world and I've just bought my first BMW, an E46 330Ci Manual '02. I'm looking to change my stock headers to something aftermarket and less restrictive. I've found some decently looking ones online but none of them strictly say that they'd fit a coupe. My...

    Selling the stock cat-back exhaust off of my 04 330ci ZHP. $175 local pick up only. Would consider meeting north east based members halfway if you toss in extra for gas.

    Hello Everyone! I own a 06 330ci ZHP and have a Borla catback system on it. I am thinking of trying the corsa UUC TSE - 3 as I really liked the sound of it. I live in Dallas, TX. If anyone is looking for a Borla catback for trade just let me know!
