    I think Vengance Racing is handling the GMMG chambered exhaust now.

    While not as loud as a GMMG exhaust, i would suggest the hooker catback.
    Its tame when just driving normally, but roars when you get on it.

    You can get a gmmg exhaust from the group purchase on ls1tech by vengeance racing or from madhammer it wont be cheap though.

    I have a friend that works at GMMG and NO they are NOT closing. Business is just slow at both gmmg and vengence. I'll ask my friend but like other have said vengence is handling the GMMG exhaust as far as an install and be prepared for a huge price tag.
