Allright you guys have my interest on the stinger catback, but ive already have the flow 2.5 catback cept i put the 4 inch tips on, if i get the xr1 borlas and weld them in will they sound like the stinger catback with the stock h. I really dont want to spend 700 bucks on another exhaust system, id rather just get the mufflers. Since you guys say they make more power and the sound is alot better i think this is the route i might go. I know ive seen another thread i just wasnt convinced. Thanks :shrug:
