Straight pipes!
 

I know this thread has been discussed before, but , i just had a few unanswered questions.
1. is it possible to just take the rear muffler off and just put a straight pipe on?
2. is the ride in the car somewhat undesireable over long distance, or is it just plain bad-ass

-thanks

remove the muffler and put a cherry bomb in place...

refer to this thread cherry bomb

Answers:
 

1) yes

2) It is a bit droning but not terrible. It might be better for you because you have a higher ratio rear end than I do.

so, if i put cherry bombs on, it is still legal, and i get a nice sound and better performance, sounds like a win win situation to me,

Is it going to be something that my mechanic is going to be like" what the hell' about , or is he gonna agree with it,

also if i opt for the cherry bomb, where can i get one?

I'd bet it would be. I've had a straight pipe for over 3 years and have NEVER had any conflict with law enforcement or passing emissions.

Other than making more noise, I don't think it will accomplish anything. I don't believe you will affect the performance either way. It may sound cool, for the first five minutes, then it will probably just be annoying.

yeah, i agree, i think it would be pretty bad ass for a while, but then it would be kinof annoying, considering it is my daily driver

'thanks for the input though!

I love it. :D I haven't gotten tired of it yet.

Hence your title? :D (Yes, I know it's Ich Will, but still)

I wouldn't mind making mine a little more quite, I'm driving about 1800 miles this weekend. After a couple of hours, noise is just noise. :rolleyes:

Good eye. :D

Since my German is nonexistent, I had to run your subtitle through the translator in Sherlock on my Mac. Here's what it turned up:

Ich will die Ruhe stören = I want to disturb the peace

Nice!

I've had 2 1/2" stainless steel straight pipe on my car for the last year (built it myself - one piece from the turbo back!) and I don't mind it at all. I don't know what it sounds like without it (when I bought the car the exhaust was so rotten it was nearly rusted through at the first bend) but most people that ride with me don't even notice it is straight piped. I don't really care for how it sounds when you are standing outside the car running (I think it sounds wierd) but I don't stand outside the car normally so I don't care. Just my 2 cents.

Since the diesels don't have cats, and every modification (most states) cat back is legal, there should be no problem being legal

It might drone a bit over 60-70 mph, but the price is right. I enjoy the stock sound of the MB on both the diesel and gas models

i agree, when the exhaust hangers finally gave out on my SD at work i removed the resonators and muffler to drive it home. And yeah it sounded cool for the first hour of driving it, my friend commented that it sounded like the buses in guatemala. I thought it sounded like a old tugboat.

Anyway it got old real fast, so i put the exhaust back on and bought new exhaust hangers! Performace was the same no real difference.

I've never heard a diesel with straight pipes before. Seems to me like it would sound more like a piece of heavy equipment without a muffler on it.

I threw a cherry bomb on my 300SD. If you keep the resonator in place its almost no louder than with the stock muffler. You will get a slight power boost and a slightly quicker spool on the turbo. You will also get about 1/4 to 1/2 mpg better mileage. The only time you really notice the noise is when you have it floored. Most of the noise comes from under the hood anyway so its not a big deal.

I used to have a BMW 320i with a Callaway turbo system on it. They still had the stock exhaust system when I bought it. I added 2 1/4" pipe all the way down and one of thoses Supertrap mufflers that has the discs in it. You can add or remove discs to change back pressure. With just the Supertrap the car had a great sound. I think the turbo muffles most of the exhaust noise so you don't need much of a muffler.

Are al the exaust mods on these cars done without welding? I'd like to try out rmoving the resonators/muffler to see how it sounds, but don't have any welding equipment.

forecedinduction used exhaust clamps.. guiloteen style(sp)


gotta love the sound of a turbodiesel with no mufflers at idle, that slight whistle is beutiful

Mine's welded. It cost me $98 for the local exhaust shop to put on.

I have an 81 300TD wagon, with turbo. My rear muffler rusted and fell off one day. I was broke at the time, fished around my scrap and clamped on a piece of pipe from an 86 Chev Caprice. There was only a very slight, barely detectable noise increase. I didn't really notice any power change. The turbo acts as a giant nuffler system anyhow. This was over 2 years ago and I have never gotten around to replacing the muffler, probably won't.

Don;t know if you all care... but in the rover community running straight pips on the tdi is very common. We have found that it decreases egt's, when they get really high on a long grade per say they can turn in to high engine temps. Keeping the egt's down has ment meaning more power and more mpg. I can barley tell a difference in the sound.

I just used some $3 guillotine clamps and some pre-form clamps. It's been holding together perfectly so far.

My exhaust system fell off yesterday (on the Chicago Skyway). It broke right under the front seats where two flanges bolt together. The flange on the foward section actually broke right off. I'm very proud of my roadside rigging job (invloved a piece of wire strung up, and pinched in the front door which vise grips clamped on from the inside to keep the wire from pulling through the door), which has lasted over 400 miles now. Is there any potential harm in running such a short length of straight pipes. I don't know if I'll be able to fix the problem soon but don't want to warp a head or something.

The sound is really not very loud at all. A lot different than a V8 gasser running open pipes!! I'm a little annoyed by the droning vibration which occurs at certain RPM. Also, I don't know if I'm crazy but it seems like I have less power (or at least an altered power curve or something). Thanks for the advice.

It won't hurt the engine, but that exhaust coming out is pretty hot and you want to make sure it isn't blowing on anything that will be harmed from that.

I ran open exhaust on a 350 Buick that ended just under the passenger seat for several months. No problems.

any other thoughts?

I just got my resonator and muffler taken off. I don't have any extra noise at freeway speed, and it's only a little louder before the turbo spools up. Once it does, it just sounds like a quiet diesel.

That's exactly right (which is not too frequent with translation programs).
