    Question another flowmaster/tailpipe question

    i have a 99 4door 4x4 blazer and want to get the 40 series single in duel out.i need to change my tailpipes because of holes,so my question is what should i do about the pipes.can i buy 2 sets that are already bent to shape or do i have to have them specially bent at a shop?im really confused. a local shop said if i bought the muffler it would cost me 300 for them to install the muffler and bend the pipes(i said fu@# that)
    also does anyone know the decibles of the 40 series?:boink:

    just go to shop and have them bend 2.5 inch pipe from muffler back.

    300 is fairly steep for a muffler and tailpipe, but dont expect it to be 40 bux either.

    run the pipes under the axle, or notch the drive side frame like the pass is so the pipe can go through there.

    just do 2.5 3 is overkill. the rest is 2.5 isnt it?

    meant to say 2.5" my bad

    there is enough room but its not worth 10 hours of fab work to be able to run two pipes over the axle

    the pipes would ahve to come together be welded together then branch back apart.

    or if i ditched my RR shock there would be plenty of room
