    you're going to have to design your own plan man... ifyou don't know where your putting it, how can you get bends.

    find a place to mount that useless excuse of a muffler, and then find some piping to suit.

    i think you'll find mounting that thing to be a bitch

    45 off the turbo
    down a foot or so
    another 45
    piping back

    so 2 bends i guess... assuming your running a normal design exhaust...

    I had to buy one of these in 3" to make the downpipe in my ED7 hatchie fit right. Ended up using the two 180* mandrels I bought in trade for other parts... What a waste, but they just wouldn't fit.

    The crossmember was too close to the outlet of the turbo for a standard bend pipe, so we had to find the smallest bend possible... that's a donut.

    It BARELY squeaked in, had MAYBE 1/4" clearance at the bottom of the DB to the crossmember.

    But OH MAN, it looked and worked SWEET.

    theres no real need for a muffler, it's quiet enough. and dont let the exhaust dump out under the car, for one it covers underneith ur car in black soot, and number 2, most drag strips require that the exhaust at the least exit the body of the vehicle. now where it exits, thats up to you.

    ive always liked right behind the passenger side front tire.
