are hooker LT worth it if i have a borla or would i need to have true duals to see any sig. hp gains?

also how much hp gain would i see if i removed the cats?

 

Long tubes will yeild you a significant gain. most of your restriction is in the exhuast manifolds, not in the catback.

Cats- a 3-5 hp gain
not worth it in my opinion. If I could, I would put my cats back on. All you need is cop to look under to get a HUGE fine.
It smells terrible
bad for the environment
too loud

worst 3hp i ever gained

 

cool. thank you
