    Default Speed Engineering True Dual Exhaust

    Thought all might like to know this kit bolts up to LPP/XS-Power headers perfectly. It was a fairly simple install. I also have a MWC torque arm with the standard crossmember for a catback. It had to be clearanced for the last exhaust I had on it and didn't have to do any more. I'm 99% sure it will work with the double drop crossmember and about 80% sure it will work with the true dual crossmember.

    The clamps suck but they're usable if you replace the bolts with grade 8. Just make sure they aren't slid too far over the female pipe and tighten the shit out of them. Although they all are still leaking just a tad bit.

    Take the time to adjust all the pipes and give them enough room to move a little and it fits pretty well. I also left all the clamps loose and pushed the x-pipe up as far as it would go with a floor jack. Then tightened down all the clamps. I didn't even use the additional hanger that uses the rear seatbelt bolt.

    i haven't taken any pics or videos yet. I'll post some when i get time.

    I didn't see a true dual kit for the LT on their site, did you use the LS kit? As far as the tightening the female slip on fittings, you could cut a few small slits into the female end, that would allow it to compress under the clamp. That's what I did to make sure it clamped tight.

    Yes when looking into this I saw the LS kit would fit the LT1 relatively easily.

    Nice! I wish I had enough clearance to fit 2 3" pipes with my Watts Link, but 1 3" barely fits.
