I'm running now LT's with full 3inch exhaust put it this way I have a Cam car my cam is a 224/228 with 581/589lift 112 LSA. I was thinking of running two cut outs in the y-pipe or one at the end. So my question is would two be better then one? They aren't cheap(electric) and the HP differences might not be different.

no noticeable difference in HP, just much better sound. i run dual cutouts and love it

there is bound to be some gain in hp on the top end, however the loss of backpressure could hurt low end torque.

not sure how true this is.

i dont htink you'll benefit much from duals with just a cammed car

SLPZ28

would a good placement for one be, right behind the y-pipe?

QCKZ28

YES if you have a good y-pipe

i ran 2 because of my crappy "custom" T pipe or shall i say T pipe...LOL...i should have bought the mandrel bent hooker y pipe...

i will run at the track next time out with my both cutouts closed and then again with both open, and see what the MPH difference is. i have 3" piping (non madrel bent) with just a bullet muffler in the i pipe then that goes over the axle and dumps at the pass side bumper cover.

I would do two just for the sound. there is nothinig like the sound of a cammed v-8 through open LT's

Wow, that just justified my purchase of dual cutouts. Thanks guys.

beware of bad ground clearance with the driver's side cutout....

Yeah I was looking at that. Kinda sucks. Guess that's the price you pay for good sound and performance.
