Default How Much E/T Am I Leaving On The Table With Y-Pipe?

I'm currently running SLP LT with no cats and 3" Y-pipe into a 3" mandrel bent Corsa over axle pipe and muffler.

What benefit would I see switching to a true dual exhaust (bullets) and dumps before the axle?

I need to make a decision! Thanks!

A 3" Y is plenty big for that combo. Just install a cuttout in the I pipe and you'll be set.

Stephen,

So true duals with a x pipe wouldn't get me any more E/T? Or not any more E/T over a cutout? How much would a cutout really be good for?

Thanks!!

In my opinion, no.

How much gain you will get with a cuttout depends on how restrictive everything behind it is. A stock muffler'd car would benefit more than one with a good quality, high-flowing aftermarket cat-back.
