No problem, took the liberty of snapping pics to see just how much 'room' there is with just a stocker exhaust in place. Not much..
Stock Y Pipe..
This was an almost impossible shot to get: Muffler inlet, Axle 'over bend', Right side outlet'

IMO, Pacesetters LTs, No Cat (Took me until recently to finally come to grips with running no cats), Texas Speed Y pipe, and SLP LM with a custom 'expansion chamber' aka 'LM1 Muffler'. Well, that or a GMMG in place of the SLP LM.
Cheap and it has a good sound. Though if you can pony up for some ORY, by all means do so. Dunno your budget so
