- Bike: Suzuki DR650 ADV
It’s not just the exhaust that strangles it, the intake is bad also.
There is a snorkel on top of the airbox, it’s a press in fit so can be removed and re-installed without wrecking anything, though it can be a bit of a bugger to get in again. As an experiment you can pull that out and on most bikes feel a noticeable difference.
Beware, danger lies ahead, once you start there’s almost no limit to what you can do to a DR.
You can potentially go a lot cheaper than cycleworks using exhausts from other Suzuki models and a different mid pipe to match them up to the header. Check out https://www.adventureridingnz.co.nz/forums/topic/eddies-adventures-dr650-build/page/3/#post-10992
