Exhaust cutout

[mrr23]

Remember, I am also nowhere near stock with my set-up.
Might be much later that a cutout would pick up power for a near stock LS1.

her's my dyno sheets back when i had one of those things on my stock car with a SLP airlid.

yes, it made more peak power. unfortunately, it made much less on the low and mid range. at the track, on nitrous, i lost .1 in the 60ft and gained 1 mph in the 1/4. overall gain et wise was .02. i took it off and went with the bassani tru-duals and picked up three tenths.

I dont have any pics but i put mine in the I pipe about a foot befor the bend over the axle, its almost like our cars were built for it there. No clearence issues and noticed a bid difference. Both in Power and ofcourse sound. I wont ever close it and for 30 bucks and an hour of work i love it. I got dyno time that says it helps out in the mid to top end range. You only need one cutout.
