I've recently started working with Stebro (http://www.stebro.net) looking after the German side of the business (BMW/Audi/Porsche etc) and one of the things I wanted to know was what's inside the oem systems. I took a grinder to an OEM muffler (albeit an E36 318i) a couple of days ago and put some quick pix up on my website (http://cpcperformance.com) that you might like to see: http://cpcperformance.com/products/stebro/oem_muffler.htm. Click on the openings to get a closer shot. I'll post more shots when I get a chance to open some up.. but I'm heading down to O-fest in a couple of days (ahhh... a nice 2000 mile road trip each way..) so won't get a chance to do that for a few weeks. Most systems are somewhat similar, the problem is in knowing which area to open up without screwing up the sound too much. You could just as easily introduce buzzy resonance at cruising speed by removing something. There is no danger in experimenting, but be prepared to mess around a lot and end up with something that sounds like crap :) (often, 'turbo' mufflers were less restrictive by design because they did not have to cancel out as much noise.. the turbo eats a lot of it..) chris pawlowicz '89 325i (stebro exhaust), '99 z3 2.8 (stebro exhaust), '74 2002 (dynomax exhaust.. loud!) ------------------------------ Date: Sun, 28 Sep 2003 12:17:35 -0700 From: Rex Tener <[EMAIL PROTECTED]> Subject: Re: [uuc] Re: front end paint chips At 07:32 AM 9/28/2003 -0700, Kevin Kelly wrote: >I used to have a guy in the Bay Area that would come out and do paintless >dent repair and also to touch up with my OEM paint but his cell phone number >changed and I can't find him any more.

Hi Kevin, I have been using Brad Treece for the least seven years or so for ding removal on all our cars and truck. He has an amazing talent for fixing even the most troublesome dings. The company I work for right now has had two ding days were Brad fixed dings all day long in our parking lot. My co-workers were completely blown away by how good their cars looked afterwards. He started his own business a few years ago, it is called Dent Performance, and his phone number is 408-227-8031 (cell = 408-210-6922). - -- Rex Tener [EMAIL PROTECTED] ------------------------------ Date: Sun, 28 Sep 2003 13:52:17 -0700 From: jkerouac <[EMAIL PROTECTED]> Subject: re: Subject: [uuc] What's In da Muffler? re: Subject: [uuc] What's In da Muffler? You could straight pipe it instead of any muffler, leaving just the cat. I also found that the round can shaped resonator used at the end of dual exhausts on late sixties GM big V8s made a nice muffler too. Weld the exhaust pipe to the outlet pipe of the cat, since the factory weld at the flange behind the cat is ~1/4 inch smaller diameter than the pipe. I found straight piping was quieter than the aftermarket buzzbombs, Supertrapps, and FlowMasters. If the outlet of the exhaust pipe angles down that too will sound quieter. High quality galvanized pipe should last at least as long as your car in the Bay Area climate. If you still have to pass a visual smog inspection, keep the shell of the stock muffler and weld straight pipe through it.

A recent many-brand comparison test that also tested simple straight pipes showed that many aftermarket muffler systems yielded greater gains than just the straight pipes. Quieter, too. Pressure-wave reversion and all that silly theory stuff that actually is good for something does indeed affect BMWs... - - Rob - ---- Original Message ---- From: [EMAIL PROTECTED] Subject: re: Subject: [uuc] What's In da Muffler? >re: Subject: [uuc] What's In da Muffler? > > You could stra...

Chris, thanks for sharing the pictures of the muffler innards. I can't say that it is obvious what would be cut out to reduce restriction, but maybe shots from a different angle would make it more obvious. My consideration of a DynoMax SuperTurbo is because of its performance in a Grassroots Motorsports magazine test. But the test was on a Golf, which has just one pipe in and one pipe out. The E30 325i has a 2 in, 2 out configuration. So, some experimentation with the pipes would be required.

Hi Scott, I don't know if this would apply to other cars, but the DynoMax SuperTurbo in my Mustang has a lot of droaning. Although the droaning in my car is amplified by the hi flow headers and cats. But yeah I got this system because it was the best in a comparison test in a mustang magazine.

Finally got it worked out in time for last weekend's track event at Road Atlanta. Many, many thanks to Chris at Bimmerworld for busting a$$ to get the second hub out to me overnight Wed, and to Bavarian in Sawanee who let me borrow a 46mm socket. And the answer was: BOTH front hubs. It was pretty easy to get these guys off, especially the right one which slid off intact with the pressure from my index finger. Yes, the inner races spun freely one the spindle. The it fell apart. The left side was a little harder. The tab holding the nut in place had broken & the nut was turned & we think heat strained. We almost snapped the breaker bar getting it off using a harbour freight jack!!! The inner race didn't come out. But the inside bearing stayed as well. One of the balls had complete disintegrated, and 3 were broken into parts. The plastic carrier was finished. We tapped the inner race out with a hammer & replaced the bearing. Now it makes no noise--well, at least not any unusual noises. The hardest part was swapping the abs rings, as we were just trying to be over-cautious not to damage them. Well, that changed too. It seems my car doesn't like the Redline 75w90NS as it started making a grumbling sound at parking lot kinda turns. Going back to the regular Redline w/out the LS modifiers should resolve this. Then it was on to Road Atlanta for Panoz's track days. While I didn't particularly care for the track, I was really pleased with the event. For those who don't know, it's basically 5 hours of open track time with instructors, who are pro drivers, on the corners to observe. I thought this was pretty good. I have to admit I fibbed about my experience & the fact that I hadn't done Road Atl before to get in the advanced A group. Considering that I was faster than all but 1 or 2 cars in the twisty bits, this worked out ok. Plus there were only 2 idiots as opposed to the much greater number in the B group. It was amusing looking at the grid for the A group: 8 Z06s, 3 Vipers, 2 911TT, 1 GT3, 1 STi, a lot of high-powered race cars, 1 E30M3. So, Sat. I was down by at least 100hp, but more than held my own through the east side of the course (turns 1-7). Sun, a couple of spec Miatas & a really powerful 02 (he actually pulled me once he got spooled up--maybe the 4 speed was an advantage too) showed up, so there were some guys I could consistently lap with. It's still fun to make up 20 car lengths in 10A on the Z06 or Viper that just blasted by & then tail'em all the way through 7. The little BMW proved it's reliability as well. I was paddocked with about 20 Z06's & they were dropping like flies. 2 popped motors, 1 jammed TB, 1 set of ignited brakes, 1 tranny failure (i think), plus a Viper with a popped V10. I asked the guys, "what's with all these crappy new American cars? My M3 is old enough to have a driver's liscence with 148,000 miles, & it's held together fine--despite the fact I'm beating it twice as hard to try & keep up." Too bad Panoz doesn't have these events at some of the tracks I like. Well, I like Sebring, maybe a jaunt there next year will be in order. 2 front hubs & a 4 bottles of Redline driveline fluid $227 replacement parts for one set of front brakes finished at the track $210 4 tanks of gas $100 watching the 405hp Z06 driver in front keep checking his mirrors 'cause he can't ditch an M3--priceless Cheers, Lee 88 M3->backing plates & rotors don't play nice together....... ------------------------------ End of [uucdigest] V3 #6785 *************************** | | In memory of Michel Potheau - friend, enthusiast, founder of the BMW CCA. |________________________________________ | Please visit these UUC-approved BMW parts vendors/service providers: | (listed alphabetically) | | Autoscope-Motorsports - http://www.autoscope-motorsports.com | |==================================================== | | Koala MotorSport .
