Which exhaust is best scorpion or ktec

[Matt1234]

Hi all
I recently brought a RB 182 after my silver 182 got written off. The silver one had a Ktec stealth exhaust. The RB has the scorpion with a decat.
The scorpion is a horrendous fit. The Ktec fits extremely well. So I'm thinking of swapping the Ktec to the RB. The scorpion has had a hanger re welded in the wrong place. Will the decat work ok with Ktec.
Thanks.
