tophats do work,but the only thing with that is,imo,its too big.
the throttle is only 61mm od (which is the same id as 2.5" tube) so why have a 76mm tophat?
its another diameter change for the sake of it.if it stayed 2.5" all the way through it would be better.
sometimes bigger isnt better....superior horsepower through knowledge,good design and maximum efficiency
version 1.0 a low boost 347bhp
version 2.0 a stock boost 356bhp.
coming next......280bhp of finest signum V6 derv power!.Comment

Hi bud, Ive got one of these and I think it has made a difference. I've also got the Induction kit, combined there is a noticeable difference - even with only the tophat change.. but this is only my opinion.
The guy to speak to is called Jack @ JBI Motorsport.
I'd be more than happy to take anyone out who's local to give there own opinion.. :-)Comment
