Redback Cat

[sillylankan]

hey guys.

i installed my catback today, while installing it i found that i had an aftermarket (i think) cat. Labelled - Redback. I was planning on getting a hiflow cat from bosimporting as well as a dump/front pipe.

The question is, is it neccessary for me to purchase the hiflow catco? or will the 'redback' be good enough.

Thanks for your time.
