Ive decided to get the K2 Gear Neo Dual Spec cat back system but im not sure what mufflers/tips to get. At the moment Im leaning towards the quad Ti tips with the heat treatment to get the blue burnt finish effect. I have heard pros and cons for both (Price difference, less weight, more noise etc) just would like to hear what you think?
You would do well to ask some people who own the K2 mufflers about sound, apparently it's not loud enough for some. Not much more than the Sti mufflers apparently.
They aren't overly loud, but they still have a fantastic note... Ask Jim Boy (Arith) he'll be able to confirm as he is one of the few that have had K2 Gear exhaust systems.
In regards to performance gain, most of it is going to be coming from the Phat Dump & the re-tune... With those parts & the tune, I would expect to get around 165kw ATW's depending on the transmission & how happy the dyno reads etc.
