stebro exhaust

[ddb]

Looking around on the Stebro sight I saw a couple of interesting things:

1) They have two different systems for the Box. The Racing muffler shown in yellowboxster01's original post, and a Sport muffler in the link I'm adding.

2) They appear to have both the Racing and Sport mufflers specifically for the 986 and different models for the 986S. I don't know what the differences are other than the base car systems are less expensive, which is good for me since I have a base.

I sent Stebro an e-mail and asked a few questions and here are their answers (you can figure out the questions):


Hi Derek, here are the answers:
1)yes , we have a sport exhaust for your base boxster. Item number: 290163104069
2)The difference are larger mufflers for better sound quality
3)Weights (factory system 78lbs, Stebro Sport system 24 lbs, Stebro Racing system 14 lbs
4)Both systems are fine at cruising speed. The racing system has a resonance around 2K rpm

As you can see when you compare the pictures in the links the sport system has larger mufflers. I actually like the sound from the sport system better (as best as I can judge from the sound clips). I'm also encouraged they mention a resonance with the Racing muffler which I guess by default means there isn't any (or at least less) with the Sport muffler.

The down side to the Sport muffler is it costs more, and weighs more, but it is still more than 3 X lighter than factory muffler if the Stebro weights are correct.

I'm really thinking about making an offer on the Sport muffler. Would you choose the Sport or Racing muffler and why?

Thanks,

Derek

For what it's worth, I weighed my stock OEM muffler from my 01 base when I took it off (muffler only, and no connection pipes or clamps), and it was 28 lbs. My Dansk exhaust that I put on was 26 lbs. The OEM PSE is about 40 lbs. No way is the stock muffler 78 lbs. I don't know how they got that number unless they included the cats and all the pipe attachments.

Boxtaboy,

Thanks for that info. on the weights. I thought I had read the OE muffler was around 30 pounds. I also read somewhere the Stebro system was less than 10 pounds. I believe the guy replied to my questions too early in the morning. I will ask him again for the weight of their mufflers.

ddb,

I took a look at the Stebro website, and I really like their setup. Here's some more info :

BOXSTER S REAR RACING EXHAUST USD$ 1,175.00

Stebro is offering this brand new stainless steel performance racing exhaust system for the Porsche Boxter S. This system was specifically designed for the Boxster S models only. This system was specifically designed for the Boxster Racing Challenge under the following criteria: Increased flow(+75%)/ reduced weight(80% weight saving)/performance cross flow design(+25hp)/ enhanced sound quality that meets or exceeds the track racing 98 db limit. This system is also offered with a set of test pipes that replace the secondary cat-converters (for race applications only) Additional test pipe cost of $300.00 is applied.

1997-2004 PORSCHE BOXSTER SPORT EXHAUST SYSTEM USD$ 1,175.00

THIS SYSTEM WAS DESIGNED TO REDUCE WEIGHT, INCREASE POWER AND FLOW OVER THE OEM SYSTEM. IT IS LESS AGGRESSIVE THAN OUR RACING SYSTEM AND CAN ALSO BE USED ON PORSCHE BOXSTER TIPTRONIC MODELS.

THIS EXHAUST IS SIMILAR TO OUR PORSCHE BOXSTER S RACING SYSTEM, BUT THIS VERSION HAS LARGER MUFFLERS TO MAKE IT MORE COMPATIBLE FOR EVERYDAY STREET USE AND TIPTRONIC TRANSMISSIONS. EXPECT EXCELLENT PERFORMANCE AND DRIVEABILITY.

I have the 1997-2004 PORSCHE BOXSTER SPORT EXHAUST SYSTEM ordered. I will document and post my experience.

78 lbs for the factory exhaust? I don't think so. Mine was about 39 pounds.

I know this because I sold one of my factory mufflers and the UPS scale was a tad over 40 lbs with packing material.

So the Stebro is not 3x lighter.

No bearing on the sound or quality of the thing, just changes the weight savings a bit.

Chris,

Awesome ! That is actually the one I am interested in

Looking forward to your review...

How much did you pay for it and where did you get it from? I think this is the route I'd like to go too. I don't want the resonance problems that people seem to have with most aftermarket exhausts. So far the PSE or a modified stock muffler like the PSE are the only options I've found without a resonance issue....

Please do post your experience once you get the PSE and take LOTS of pictures.

I asked Stebro to double check the weights they quoted in my post above and they sent me the following:

I took the time to get some accurate weights:
Stock system 39.5 lbs
Stebro Racing system 10 lbs
Stebro Racing system 18.75 lbs

I'm sure he means Stebro Sport system (instead of Racing) 18.75 lbs.

So the Racing system is almost 4x lighter than the stock system!

At more than 2x lighter the Sport system offers a nice weight savings as well. One that I will gladly accept.

I'm not getting the OE PSE, i'm getting the STEBRO Sport Exhaust. I don't expect to get rid of the resonance with this muffler. I have a GHL so anything will be better. I bought it from eBay and i used the "Make an offer" option. If your not in a hurry and your interested in this muffler wait for my posts. I just paid for it yesterday, it will ship from their Swiss office to Ottawa, then to me. I expect 3 weeks or so. He had 10 available on eBay before i bought. I notice he now has 8.
