    My new (to me) 308 76 euro fibreglass has only one exhaust exit on lhs. I have seen some cars with twin exhaust on each side, and then some of them have a 'box' around them. Is this aftermarket, or did it leave the factory like this.
    Do the twin exhausts make a difference?

    Single lhs is standard - quad comes for two reasons - either loud quicksilver type or standard later (or Gt4) four pipe - usually added for cosmetic reasons only

    If you mean the tailpipes come out of a small secondary box, then your probably looking at a "thermal reactor" 308 exhaust.......apparently used to try to reduce emissions

    KershIrl,

    Your Euro 308 GTB Fiberglass looks like Picture #1

    Some Euro GTB owners replaced their single outlet mufflers with an ANSA Sport muffler as in Picture #2

    The 1976 North American Version 308 GTB Fiberglass came with a thermal reactor muffler with twin pipes on each side. My original thermal reactor muffler resides in a corner of my garage and was replaced with an ANSA Sport muffler (Picture #3). Note there is no cutaway on the valance as on yours.

    The early steel GTBs had the slotted screen or 'box' as you mentioned, installed at the factory (Picture #4).

    Hope this has helped.

    Barry

    i think i am really wanting a set of those euro amber lights......

    my old GTB now has a REALLY cool system on it. guy took a 1976 genuine factory single system and made one up to fit a USA spec car. that way you can loose the rear ugly " metal diaper " around the exhaust and have a "euro look". he can do them with a black single out or a polished one. i will have to ask the muffler brand. a friend of mine that posts on here ( JFRAZAR) can have them made for under $1000.00 i think. i will get some pics this weekend and hear it for myself on my old red 77 GTB.

    thermoreactors i guess are valueless and dangerous fire hazards now!
