    slp loudmouth

    I'm considering buying a used SLP Loudmouth I cat-back system for my 1999 T/A.
    The guy I'm buying the system off of is taking it off his 2000 T/A. The system has been on the car for a little over a year with D/D mileage. No cracks or splits.
    He doesnt have much knowledge on how much the system is worth, so he asked I throw him an offer. I'm thinking $200 would be a reasonable offer.
    Just making sure I'm not over paying. Looking for some feedback.
    Thanks

    Steer clear if you EVER plan on putting headers on the car.
    Sounds like a dump truck with headers.

    When I bought mine from Summit in 05, the loudmouth exhaust was $313 shipping and handling was $24.00 but the freight also included the Y Pipe

    To each their own.

    I HATED the sound of my car with the Loudmouth and longtubes. Had hi-flow cats.

    I have the SLP LM2 with headers and it is EXTREMELY loud at WOT. I think it sounds good at idle (with a big cam), good when you're cruising, but punch it and you'll get a headache pretty fast.
    Oh and it doesn't have cats so thats probably a factor.

    I understand the sound isn't what you were looking for, but what about the performance?

    I am looking at cat-back exhaust, ceramic long tubes and Y-pipe. I am really looking for the old-school muscle car sound with kick ass performance. Any suggestions?

    I have the LM1 with long tubes and no cats and I don't think it's really that bad at all. If I take the car above 3k it starts to get a little loud but other than that it's no louder than any other modified cars around here.

    Magnaflow.

    Performance wise...the car was okay. Same as any other cat-back for the most part (aside from Flowmaster).
