Title: 1100S exhaust mods Post by: MountainFergus on November 02, 2018, 01:25:24 PM Hi.
I have an '09 Monster 1100S and I'm considering my options regarding exhaust. My first question would be: Do Evo pipes work for my bike? Second question: Has anyone here gone from stock headers to 70 mm? Thank-you. Title: Re: 1100S exhaust mods Post by: stopintime on November 02, 2018, 02:31:45 PM 70 mm is probably pointless. Only if the intake and combustion required 70 mm to be in harmony. An 1100 two valve bike won't get around the corner if it was tuned to a degree where it needs 70mm.
There's a sticky thread about 696/796/1100 exhaust mods. .... and: welcome [thumbsup] Title: Re: 1100S exhaust mods Post by: Speeddog on November 02, 2018, 09:45:10 PM I don't think there's enough horsepower there to need 70mm.
One of my customers has a HYP1100Evo, it has a super nice aftermarket exhaust, from memory it tapers up from stockish to *maybe* 50mm. I can get more accurate numbers, as I've got a slightly squarshed lower headpipe in my exhaust bin. Title: Re: 1100S exhaust mods Post by: MountainFergus on November 03, 2018, 07:01:04 AM Thank-you.
In this case it's not for power. It's for sound. Title: Re: 1100S exhaust mods Post by: MountainFergus on November 05, 2018, 11:17:14 AM If bigger headers are not practical or sensible, who makes the deepest sounding exhausts for my bike?

Title: Re: 1100S exhaust mods Post by: Speeddog on November 05, 2018, 03:43:14 PM ~~~SNIP~~~ I can get more accurate numbers, as I've got a slightly squarshed lower headpipe in my exhaust bin. 40mm at the head, tapering up to 45mm about 150mm downstream. Title: Re: 1100S exhaust modsa Post by: geoffduc on November 06, 2018, 10:01:58 AM Have a look at Sparks carbon twin can set up which comes with pipe work that gets rid of the flapper valve, it's a beautiful system that's a lot neater than termi's and sounds awesome plus it shows off the rear wheel rather than hiding it which some replacement systems do.

Love my Arrow cans, and I know cans with bigger inside volume will tend to be deeper. The trademark Ducati boom is good for my ears and my spirit, especially in the mountains where I live. SP Engineering has 'big bore' cans, stubby and full-length. Would prefer something carbon and Italian, but not dead set on the latter. Does Termi offer big bore slip-ons? Thanks, Speeddog, but if they grew to 70, that would be more compelling. Title: Re: 1100S exhaust mods Post by: Speeddog on November 06, 2018, 04:43:04 PM Just out of curiosity, how do you plan to route some 70mm pipes?
Title: Re: 1100S exhaust mods Post by: MountainFergus on November 07, 2018, 09:26:23 AM Not entirely certain, but I was counting on my good old Scottish ingenuity to find a way.
Through the frame with a removable oval section maybe, or giving up the under-seat configuration if I had to. A good, creative fabricator and I could find a way, I think, but I'm willing to compromise. If I have to resort to the biggest, deepest slip-ons I can get with the current pipes, that wouldn't devastate me or anything. It's not that I'm disappointed in how it sounds. The Arrows I have now with db killers out already sound very good. |
