Trying to figure out my next mod. I was thinking of going with some ai heads for my sierra , but now im considering doing some true duals with cutouts. The question is, would it be worth it (dollar per horsepower wise) to switch from my current, pacesetter lt's to y-pipe, to 3" flowmaster, to passenger dual 2.5" side dumps, over to true dual 3" pipes w x-pipe and electric cutouts? Also, would it be beneficial to run cutouts before or after the x?

And btw my truck is stock lq4 bottom end, 706 heads, 150 shot, and ran an 11.8 @112

I'm sure you've seen this. https://www.performancetrucks.net/fo...totype-538474/

For the price it might be worth it. Local exhaust shop should be able to make it work with your Pacesetters. With the straight through muffler design you wouldn't need cutouts from a performance standpoint.

I actually hadn't seen that before. I just wanted the cutouts for the reason that I could drive it around town fairly quietly, then open it up for the strip, or whenever I feel like making noise.

Also, Sorry should have made it clear that I have 706 heads milled .030 and a mild 224/224 cam

a pair of long bullets will be mildly aggressive at idle/part throttle and loud as hell when you put your foot in it and want to make noise.

May need additional modding to fit around the 4l80e too
