True dual 3" would make the most power. A 3" y pipe setup will work as well. Just make sure the Y is a smooth transition. Basicly like a Y shape.

well im going to hit the track this weekend and see what it does im under the impression its underperforming, then ill do the true duals and go run again. i barely got a new trans in so i havent eaced it much. but i lost to a 2018 5.0, bolt ons e85 tune with drag pack. it wasnt bad about 2-3 cars but i was sure i could beat him.

that 10 speed plays at the strenght of the 5.0 with the way the gears are set up. those run very low 12s stock. i beat a 2017 tuned bolt on 2017 ss when i had my old trans going out same camaro was gapping c6s. i beat his 2015 too. im hoping its my exhaust restriction also gonna do a bigger maf later on. my tunner says i need a 4k stall. im running 3k with 322 gears.

did a consistent 12.0 @ 115. could have had an 11 but i spun on last run then somebody crashed, so i left. 1.7 60ft. in the video you can hear the car bog down a little off the line its running a bit rich and needs bigger stall. currently 3k stall with 323 rear end. will post after i do full exhaust. would high flow cats hurt much?

its got be my exhaust and not proper gearing for my cam. ive always felt my car hasnt been running like it should sinc ei started on it. plus the guy with the 5.0 could have lied about mods last time i ran his 2015 he said it was exhaust 93 tune. but before he sold it a few weeks later he posted cams, 2018 intake, and a few more bolt ons he had on the 2015.

What cam are you using?
What headers and primary sizes?
What rear gear?
I may do an lq9 with ls3 top end and I’m trying to see what cam to go with?
I thought with a big cam and ls3 u need to rev it high ?
