Exhaust (CT1 on a CT2) was created by Schu

Does anybody know if a CT1 exhaust will fit on a CT2?

If you use the CT1 shock mount, yes.  Bolts right on.

CT2 exhaust onto CT1 is not so easy.

Just wondering...  I'm not sure I've seen an aftermarket pipe for the CT2/CT3?  I wonder if they just stayed with the CT1 mount?

Of course I'm probably wrong and I'm much more a fan of the CT1...  mostly because I hated the flip top gas caps.

I have several aftermarket AT/CT pipes and I'm pretty sure they all have the early mount system...  even the one on my AT3MX.

Hey Schu yes it should the difference is the rear mount is on the shock for the Ct1 vs under the seat for a Ct2. You would just mount it to the shock. My Ct2 had a chamber mounted to the shock but I put a stock Ct2 pipe back on under the seat. I might sell my expansion chamber as my son rides on the street more.

Thank you both for your responses. That’s what I was hoping to hear. I may be picking up a CT2 and I have a really nice Hooker Header from a CT1. The Hooker has a band clamp at the outlet, so I assume I can make it work, should I end up with the CT2.

I'm with ya markt, not a fan of the flip tops! Much prefer my rt1 tank over the rt3 tank. Although you'd have to be having a really bad day to misplace the cap on a flip top, lol.

My aversion came from my used LT2 as a kid that yes, I rode the heck out of off road.  It would randomly dump gas out the cap which invariably ended up soaking the inner thighs of my blue jeans which hurt like hell and even caused blisters (chemical burn). Of course I just kept riding and most of the time I pretty much had to. 

Never figured out why it did it.  More likely to happen with tank nearly full.   The bike was only a couple of years old when I got it and the cap seals seemed good...  It would just randomly puke gas on a rough trail sometimes.  Not every time, just sometimes.

I am not a fan of the push down, pull up design. Two hands almost required.
Cold weather my finger always hates jamming that button down, especially after riding it without gloves. That might be more my fault, but hey I look for convenience in this world, lol.

I had that Hooker chamber on my original CT-1, but I'm pretty sure it had the same mounting setup as the stock pipe, with spring attachments.
