Suzuki C1500 ( Boulevard C 90 ) DIY exhaust mod

Make some noise ! ! !
Orginal exhaust in orginal shape, is so quiet.
So, after this you don´t need to order 500 - 1000 euros specified exhaust ( Silver tail, Cobra, Vance & Hines)

What size drill bit did you use. I’m doing this today

[@tomhubbard7763]

why not take the whole damned baffle out

[@paulmcdowall5544]

Why drill 4 holes in the upper exhaust and only 1 in the lower exhaust? Did you notice any performance impact or gas mileage reduction? Do you have a stock air filter, or do you have the K&N air filter and fuel processor?

Hi. There was few days those 4+1 holes, but now 4+4. This is only for noise.
I have normal orginal airfilter, and no fuel prosessor. just regular things as a new one.
I think those holes dont save or spend gasoline, My calculating dont show that. Its pure noise thing. /and save money, becouce dont need buy new pipes (cobra, V&H etc...600.900 euros)
Normal highway driving 4,5 L /100km. and city driwing 6,05 L / 100km. these are easy driving numbers ;)
