PanzerAce Posted September 18, 2008 Share Posted September 18, 2008 So this isn't a 'which brand is best' thread, but rather, within reason (ie, no open headers), what kind of exhaust system would you run on a L30? I'm trying to figure out what I want for mine, so I'm looking for ideas/advice Quote Link to comment Share on other sites More sharing options...

johnc Posted September 18, 2008 Share Posted September 18, 2008 For a street car: Stahl 1 5/8" primary header coated with JetHot 2000. 2 into 1 304 stainless merge collector with a 2 1/4" throat, 7 degree cone, and 2 1/2" outlet. 2 1/2" 304 stainless exhaust all mandrel bends. Borla S-Type Resonator. Borla XL Turbo muffler. For a race car: Stahl 1 3/4" primary header coated with JetHot 2000. 2 into 1 mild steel merge collector with a 2 1/2" throat, 7 degree cone, and 3" outlet - JetHot 2000 coated. 3" mild steel exhaust all mandrel bends - JetHot 2000 coated. Borla XR-1 Raceline muffler. Quote Link to comment Share on other sites More sharing options...
KillerBjt Posted September 18, 2008 Share Posted September 18, 2008 Johnc i dont mean to thread jack but why go with the mild steel for the race setup and the stainless for street? Quote Link to comment Share on other sites More sharing options...
johnc Posted September 18, 2008 Share Posted September 18, 2008 Race car exhausts don't last long. They tend to get ripped up with jumping curbs, going off track, scraping on trailers, and they spend a lot time being taken off and put back on. Stainless doesn't gain you anything over a coated mild steel exhaust on a race car except double or triple the material costs. There are exceptions - high power turbos and very high compression NA often require the additional heat resistance of stainless. Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted September 19, 2008 Share Posted September 19, 2008 I have 3" mandrel bent stainless on my car with the XR-1 muffler. It sounds very nice. Then again, I have another "muffler" made by Holset to quiet things down. It's not overly loud, however. Quote Link to comment Share on other sites More sharing options...
PanzerAce Posted September 19, 2008 Author Share Posted September 19, 2008 JohnC, don't suppose you know anywhere that won't charge the (nearly) grand that Stahl wants direct? Quote Link to comment Share on other sites More sharing options...
johnc Posted September 19, 2008 Share Posted September 19, 2008 don't suppose you know anywhere that won't charge the (nearly) grand that Stahl wants direct MSA sells them but the price is about the same. Its actually a reasonable price considering the quality and how ell they work on the L6. Quote Link to comment Share on other sites More sharing options...
