| Post subject: | failed inspection |
I need a new tie rod end, but I'll order that tonight. I need an on/off switch for the foglights; where are auto parts stores in K-town? The exhaust is too loud, 101db. I had some steel wool in the exhaust, but I don't think I can cram enough in there to pass inspection. I've been looking at bullet mufflers, but Dynomax only advertises a 2-4db change and the other brands seem too large. I already have low exhaust in the front and I don't want more problems. I'm debating a new muffler because of that. Gary, do you still have the stock exhaust on the Hawk? And finally, I need to remove the front window tint. Oh well, I guess it could have been worse... |

Man I failed with 103 db so I stuffed a bag of steel wool in each pipe and it got so quiet I didn't get a db test the second time. Good luck!!! |

I emailed a few companies and Moroso says I could see about around a 7db decrease. It doesn't look too restricitive either. I don't see how you can fit a whole bag in each pipe, seems like it would blow right out! |

The More the better, it does the trick. I use Supetrapp so I can adjust the sound witht he disc as needed. |

Yes the steel wool works . But you want the wool in there as loose as possible with out it blowing out . also be gentle on the gas pedal . |

I was pretty gentle on the pedal, but the inspector jumped in the seat and blipped the throttle a few times before running it up. I crammed some wire mesh behind the wool to hold it in place, and it held but I didn't have that much wool in there. Right now I'm thinking about adding a Moroso resonator. It's only 4" in diameter and should give enough db reduction. I'll probably add steel wool again, just to make sure. |

Don't let the inspector do it is all I can say. |

I actually failed the inspection at Vogelweh, is the Ramstein shop the same? I just got a Moroso spiral flow that I was going to add to the I-pipe, they're supposed to be low resistance but reduce the db by 7. I hate to add it, but I am tired of the "rifling" during deceleration, so maybe this will help... |

The Vogelweh inspectors are a bunch of a$$holes. Ramstein isn't that bad. |

I installed a silencer in the I-pipe and then stuffed a bunch of steel scrubby pads in there upstream of the silencer. It was so quiet, they didn't test me 2nd time through. Plugging up one of the tailpipes makes a large reduction also. |

Stock LS1 w/ Resonators = 96db - 1 over the limit (Mannheim allows 95 for whatever reason) So steal wool time. |

Hm ... just noticed this weekend that at idle, my Firehawk (stock all the way through) is actually a bit louder than Roy's SS ...  First time I was able to see Roy move his car without hearing it!
So I reckon it would most likely not pass the US inspection ... |

You don't have the SLP Loudmouth installed, do you? I have the spiral flow in teh I-pipe now. It still sounds Ok and it has taken care of the rifling, but I miss the more aggressive sound.
