    i was told the GTPs can't get true dual exhaust, is this true? I was hoping to get headers and true dual, but would true dual even be worth it over single then split to 2 mufflers?

    you could do it.

    but you'd be stupid because it'd waste money that could go towards things that matter like heads or a cam and because the stock catback will prolly be more than good enough for any setup you'll prolly run. most run into tranny issues before needing an aftermarket catback lol. and they're not cheap...

    thank you for saving me some money haha, i was planning on getting headers too actually, but i thought true dual would be more efficient for my exhaust then what im running now which is 2.5 inch stainless steel pipe from cat to 2 mufflers, should I get 2.5 inch before the cat too? for some reason the amish people wouldnt touch anything behind the cat....they do a hell of exhaust work though for really cheap =\

    Just get headers, they all come with downpipes except for TOG's and ZZP's but most people dont buy those because they're really expensive.

    the catback you have now is good for quite a while.

    remember this is just a tiny little 231 cubic inch engine, not a 350 or something larger haha.

    for the record you cant even have "true duel" exhaust on our cars... so you can just eliminate that option...

    you could... it'd just be stupid.

    Run front pipe like the crossover then go above the rear mani pipe through the tunnel then you could go side by side or on top one another the rest of the way back.

    small pipes.

    it'd be ratarded though.

    its a transverse V shaped engine.

    Of course true duals would be 100% custom lol.

    It'd be a complete waste of money though.

    he is one of the only people who ever did truly custom mods to his car, hense why he was able to pull off a 12.11 second 1/4 time on a rocker car.
