??cut-out/true dual gain for my application?? How much if anything do you think I'm leaving on the table?
I'm curious to know if significant gains can be had by doing a cut-out just after the "y" or running a true duel 2.5".
I'm assuming yes, just would like to here thoughts from others who have had experience.
Opinions welcome. Thanks.
TTS longtubes, gutted cats, y-pipe, borla wide open
forged 346, 9.1 comp, D1SC @ 13-14psi, H/C
614 rwhp/ 537 rwtq

With the kind of power you're making, you're leaving power on the table with anything less than a 3" y-pipe into a 4" catback or a 3" true dual setup. How much?.....I dunno.

Thanks for the feedback. Yeah, I figured that.
I'm really just weighing the hassle of changing the whole exhaust or just throwing on a cut-out.
Duals would be better but the cut-out will be easier. A potential problem might be "wacking out" the tune when it's open/closed. By how much, I'm not sure.
I'll probably just toss on a cut-out and see what happens.
