Got my scooter in for its 1k service. At the same time I want to put some slip ons on. I heard the CFRs are nice. But I hear about a torque loss. Does any one have any insight. It’s an 18 with the 117. And other recommendations would be appreciated.
If you have the stock header (which has the catalytic converter in it), you won't have much if any TQ loss with the CFRs. The CFRs are a problem if you have a non-cat header.
Also, with a non-cat header, the CFRs are LOUD. Not bad with a cat--have a nice rumble.
This is from my experience with both cat and non-cat systems. Currently running knock-off CFRs on my 2018 RGU with HD Stg 3 kit and stock header (to keep TQ loss in check). Googled and bought megaphone mufflers for $185 w/ free shipping. Made sure they were for M8 engine, not TC.
