207hp with Cams and Pistons

I was hoping some one would speak up, I was thinking the diameter of opening of headers?
If is the case is the opening on headers for Jardines good?


My understanding is that is the header size. Seems anything smaller along the way would be an "obstruction" to a greater or lesser degree. I'm no expert, so here is the list of options I was given. I went with 2 1/4" with heat shields and their muffler......

CES TRIUMPH ROCKET III

CES PERFORMANCE HEADERS 2.1/4”

(headers designed for our CES muffler size upgrade)

CES PERFORMANCE HEADERS 1.3/4”

(headers sizing to maintain your original standard muffler )

Are you stating here that CES is now making a 2¼'' at the header and in stainless system?????
If true, I be stoked!
 
Any pictures of these headers and exhaust?
And they come three in to two exhaust as well.
Dow they sound as good or better then Jardines?
 
Thanks mate, that is very interesting and will share with a few mates. Yes it was a coffin tank, the first release, light blue in colour. My very first road bike and my Mum copped a lot of **** from my Dad for buying that bike for me. Didn't kill myself though, just had a whole lot of fun. My mates had a Suzuki GS1000 and a Yamaha XS1100. Geez we had a good time riding those bikes
 

Amen! I've many great memories of many rides around the country I did through the 70s! So many, they kinda run together in my old head.
