Thanks for the reply's fellas, LORENZ-GS06 thanks for the info, I'd like to see some more pics if you don't mind, whenever you get a chance of curse.
I looked at the post Icdave shared (thank you Icadave) but I can't make out much what baffle and what else needs to be cut so if you care to elaborate in some more detail I'd highly appreciate that.
Maybe you are right about the fact that it's probably not a good idea to gut the whole thing because I already removed my secondary cats and resonator so maybe a straight through exhaust would be an overkill but as of right now the sound hasn't improved much and definitely not much louder worth to mention, I'll see if I can post some video clips.
