Rear Muffler

[Alexlind123]

I have been thinking about replacing my rear muffler with something a bit more "exciting" Does anyone have any video or coud clips of m30 exhaust? I would like some feedback as to what any of you might have tried and how you fele about it.

glasspacks. Go to roadfly E32 board and see the picture gallery E32. I posted there pics of the glasspacks they made for a 735 E32. Complete exhaust is shown there and while they weld it.

I got an Eisenmann Sport performance (old version) on mine. At idle it has a nice mellow tone. It only roars at full song. There is presently a rare ANSA muffler on Fleabay for the 535i with dual 3 inch pipes. Never had lasting success with the ANSA on my 2002 as mentioned in another post because they typically rust inside out sooner than others. Good price though and it should sound pretty good.

and removed the center resonator and replaced it with stainless steel straight pipes.....

The wife could always hear me coming from 1/2 mile away. The drone inside the car was worse than the exhaust actually sounded. Maybe if I had left the center resonator in it would have been more tame.

After I get done with the 535iT project, that same exhaust will go on that car. I'll try to take some video when the project is done.....mid Jan. I might be too late by then for your purposes though.

I like the Billy Boat Tri-Flo Exhaust. It is inperceptible inside the car except during acceleration. But sounds really nice outside the car. It is on sale i think at BavAuto. (no affiliation) otherwise talk to dennis hannes at Billy boat (no affliliation) - JT

He's looking for 535 application. A buddy of mine has a Tri-Flow on his 1990 535 and I'd say the interior noise is definitely perceptable. In fact, it's a shade below my setup and he has a center resonator whereas I don't.

I think Martin B or Jeff N have a Tri-Flow that they took off their car....they can opine on using this long term.

I have the tri-flow on my 89 535. At dead idle it is pretty quiet.

Driving, it is definitely noticeable inside the car, but not to my mind bothersome unless you have the windows down on the highway: Then the exhaust plus wind noise can be tiring on long drives. It does however sound really cool to hear the back-pressure clear when you lift, almost like a turbo car's boost over-run after a down shift.

Outside is another matter - Its pretty loud. I like it, as I can always hear the car coming when a parking lot attendant is pulling it out of my building's garage. You can also hear it from down the street, but it is a nice rumble, not the nasal buzz that comes out of some kid's "Fast and Furious" four-banger.

Am I hearing a lot of piston slap in that first audio clip?
