best slip on for 08 z400

[josh burden]

my brother just bought a left over 08 z400 and me and him were wondering wt the best slip on or full system would be for it

I have a Motoworks slip-on and just love it. It's not too loud and provides some good punch. It's around $295, but I've seen it as low as $200 if you catch the right sale. The quality and workmanship are rock solid. I'd buy it again.

I put a Jardine on mine and it sounds good to me.

i run a t-4 pro circuit,its got great sound and a great botom end boost!! cost around 300,but they all do.

check out ctracing.com. that is what i am getting. they have a link from dirt wheels magazine that has a test of full exhaust systems. dont get a slip on. spend the extra money.

Speaking of full exhaust, what performance changes will a header provide? I’ve read a few articles where the manufacturer claims the header will give “10% more exhaust flow” but what does that mean in terms of real performance? I have a slip on and have considered a header, but would like to hear from those that have them what difference they really make. What does $200 extra buy me?

josh the best exhaust overall is the new TRC Titanium full system by Yoshi and the purpose of a header is that the end of it in general is wider (in most cases) but for some the whole design is wider in diamiter 99% shure on that one

let this out, MORE AIR FLOW!!

[Joshbeasley]

yes an aftermarket header is normally wider in diameter. too much air flow can actually loose horsepower. the whole design of the header affects horsepower also along with the length of the pipe and the silencer.

i did see a test in an old dirt wheels magazine where they tested a yoshi slip on without the airbox lid and i believe it made .5 hp.
