i was wondering if anyone with a removed exhaust has any dyno numbers? and if so is it removed from the axle or the s-pipe?what im trying to say is, will there be more gain with it removed from the s-pipe or axle.i already found that removed at the axle will give a gain of 5hp. link to source (https://www.scionlife.com/forums/viewtopic.php?t=80070)

if gains are good im planning on having an electrical cutoff valve

 

I dunno, but if the exhaust ends right after the S-pipe it's prob'ly going to be real loud.

 

should be about the same.

if you remove it from the s-pipe back or axle-back the gains will be negligible.

also, cut-offs wont get you a gain of HP if thats what your thinking, on NA we need back pressure, its turbos that live off of cut-offs, not NA.

 

ya cut outs = tourqe from what i understand from the ___ camaro buddies
