Good discussion keep it going. I am very interested in gains that can come fairly cheap as well. I also want to avoid fault lights. Cat back systems and mid sections are all just outrageously priced. One reason I am keen on a cut out system. My ideal system is one that:
1. Includes a quiet/loud option such as with a cut out.
2. The quiet option would be the same or ever so slightly louder than stock.
3. Gets you 10-15 hp.
4. Costs < $1000 total.
