This is a y-pipe back system? Or is the 5hp with a aftermarket Y-pipe?

This is a y-pipe back skystem.. I dont have an aftermarket Y-pipe, just pop charger. I got my pop charger w/in the same week or so, prior to exhaust, so it was hard for me to tell if the lil power i felt was from pop charger or exhaust.. I figured it was from the pop charger, and pretty minimal from exhaust. Sounds really nice tho! Besides, exhausts on NAs are pretty much for the noise, from what i hear.. Probaly feel most gains after I install my test pipes..
