muffler delete(just straight pipe)

[haso]

I was wondering if anybody knew what my car would sound like if i did a muffler delete and just put on a straight pipe with exhaust tips??

ohh and i have a 86 325e 5spd

really loud. probably a bit raspy too.

My '85 325e has a straight pipe after the cat. It's loud. I like it :)

I don't think it's that loud at all. :shrug: :p

well, I have a cat, but besides that, no other restrictions. I honestly think it doesn't sound ricey at all, and not raspy either, and barely drones enough to be considered droney, especially at freeway speeds.

I will record a video for you guys soon enough, but for now, here is a first and second gear jaunt for you.

I never had an issue with it in the year or so I had it like that. It acutally ended up rusting off just before the resonator, so then I routed it out the back. I don't own the car anymore either.

what piping size should i go with 2.5???

[e30_325es]

Mine was stock 2". 2.5 would be overkill on a stock eta.

i had straight pipes ( no cat) on my 318i 2.0l and have the same pipes on my 3.5l (post swap same car) with the small 6 it had a unique sound....not like a ricer but not throaty like an american v8 somewhere inbetween with the stock pipe diameter. just try it for a while....loud as hell, the neighbors won't like it but it's sure fun making people wonder what you have under the hood

Hahah, that's hilarious :D



Anyways, 2" is good size for 325, so no idea putting more than single 1,5" to an ETA..

I've 2x2" in my 335 and they're a bit too big for it (room for more power though)
