My Ride: AW E46 M3
Just installed a Top Speed muffler

So I finished this installation and thought I would update with my findings.

Holy crap it is AWFUL. The sound could not be any worse. It's LOUD and RASPY starting from idle all the way to redline. Sound is similar to a straight piped Civic.

The car with no muffler (open Section 2) is about a 10 loudness.

With the exhaust, it's a 9.

At least with no muffler, the car sounded exotic, albeit loud. With the exhaust, it sounds like shite AND it's loud.

I have an AR20 on the way and will weld that in to see if it helps. But if not, this exhaust is going in the trash. I'm throwing my stock exhaust back on until the AR20 gets here because I'm embarrassed to drive the car like this in public.

The only good thing about this exhaust was that the fitment was very good, so there's that at least. Hopefully the AR20 will quiet it down.

Thanks for the review, I'm still deciding what to do about my stock exhaust. The only thing positive about your car is that even if it sounds like a *****, at least its fast. ;-) I've decided I'm going to start with a modified stock exhaust and if that doesn't work I'm using a dual-in dual-out Magnaflow.

A two minute google search on this muffler could have saved you a ton of time. Next time you decide to cut corners on your m3, consider looking up reviews and sound clips from members who have done the legwork for you.

Get headers and sound will change, any muffler with cats and US headers sounds like a Civic. Headers makes the car sound totally different

Yaas. I have the bimmerworld street exhaust on mine and it basically sounds like a subaru (lol). But paired with the correct headers like my buddy's and it sounds gnarly. Don't lose hope on the topspeed exhaust just yet

I got it for a $100 on Craigslist and it took about 45 mins to install. Didn't really waste time or money.

"cut corners"

Lol! Get off your high horse, you know this is a rep of the more expensive systems.

Will do. I'm hoping the AR20 changes the sound or at least quiets it down a bit. Do most headers sound the same? I'm probably going to get Euro headers just for the fitment ease.

Car is currently on jack stands, as I'm doing a little maintenance, but you're close by. If you want to PM me, we can meet up somewhere and you can hear it in person. A video probably would make this exhaust sound cooler than it does in real life lol!

Every catless setup will sound the same. Keep in mind - headers do make the car significantly louder.

I only saw it on Craigslist once, and I check pretty regularly, but yeah it had black tips. I used lacquer thinner to remove the paint. I prefer metal tips.

The one that had silencers in the tips? Because that's how I got it. They look ricey as hell but without them the car is pretty much undrivable with how loud it is. My AR20 resonator will be here on Thursday and I'll be welding it in asap. If it doesn't help you can have the exhaust for the $100 I paid for it lol.

Yep! It was on CL for a long time then he took it off for about 2 weeks and reposted it. I think it was on a black or grey car. I asked him about the painted tips and silencers. You might want to try using 2 AR20's (replace the stock one thats located in sec1)

Yup that's the one. I figured I couldn't go wrong with $100 for a stainless steel muffler, but it's pretty obnoxious. Like I said we're close by if you want to hear it in person.

Update for anyone that cares. Got my AR20 welded in today and WOW it dramatically changed the sound. Sounds really good now, and the volume went down noticeably. The exhaust, in my opinion, sounds great but is still a bit too loud for me so I'll probably get rid of it. I'll try and get some videos this weekend.

I want to keep it for a week or two just because it's kind of fun now that the loudness has toned down a bit and it sound really good now with the AR20 welded in. But I'll definitely PM you when I sell it!
