Great Job Tom. This is the kind of comparative dynos that are needed in the Aftermarket space. These results provide good data to for those who are skeptical on gains from filters and pulleys, especially when used together. Naturally, a catless X-pipe does provide the most bang for the buck, but it seems that solid gains can be made from the combo you provided.
