Okay so i plan on getting Greddy 4-2-1(onepiece) header soon for my 4dr ls. I already have the greddy sp2 catback and i wanted to match it all up greddy 
Since im planning on getting the header soon, i figure i might as well get a highflow cat to complete my exhuast. I hear carsound or random tech. are the best. The only problem is i wanted to be able to bolt on all of this!
Do they make a bolt on highflow cat for my car?
Were can i find this?
I want to avoid welding and shops at all cost ha.
Or you think i should just keep that old stock cat with new headers and my exhuast?
Will it be worth it to go ahead and get the cat too?
help! and thanks.
