Guys,

I recently fitted a baffleless, Blueflame twin exit race can onto standard downpipes with a link pipe. I assumed the back pressure wiuldn't change greatly with standard downpipes.

The bike seems to have lost its grunt low down. It was previously very responsive and snatchy below 7000rpm and took off between 7-10.5rpm, felt like an extra oomph.

Since fitting the new exhaust it seems to be more lethargic, less responsive and more revvy to the redline with a flatter, steadier power curve.

I also had new chain and sprockets fitted at same time and part of me thinks it may be the different ratio sprockets from the s model, I'll nip out and count the rear teeth now in fact. If it ain't that then I'm assuming I'll need filter and dynojet?

Thoughts.
