EXHAUST SYSTEMS

[Dyno]

Exhaust Systems

This is one of the most unique and valuable files we are making available to all. Here you can see how exhausts, you may be considering, perform with motor combinations, you may also be considering or already have. You will also see how the same exhaust may work well with some motor combo's but not with others. Here, you will see some repetition in the combo's listed, to demonstrate the inconsistency in performance. This is why we typically give a range for HP/TQ expectations when discussing performance upgrades. Last and most dramatically, you'll see how large an influence the exhaust has on the shape and peaks of the HP and TQ curves.
Questions about what exhaust works best are the most common we get. Consideration of how any one exhaust may impact a proposed performance upgrade occupies the largest part of these discussions. Our recommendations are based on the same data shown in these folders.
Folders are only available for brands and types that have been tuned on our dyno. There are a large number of systems for which we do not have data. Folders will be added as bikes having systems new to us come in for tuning. The relevant run information for each has been put into the graph titles.
One very interesting folder is the "Tests and compare" file. This will show the most dramatic effects of exhaust systems or modifications such as baffle changes. Most of these graphs are for the same bike, tuned to each change for a true A/B test. Others are actual tests or just things we've encountered as part our dyno work.
