I'm thinking ahead for next season and an exhaust mod is on my list of things to do. I doubt anyone will see big gains (>5hp) with catback swaps. So it's hard to justify spending much money for this.
What I'm wondering is if a cut-out just beyond the last cat might give decent gain at low cost. It would also be nice to close off the cut-out when on the street. One really cool set up I saw on a Z-28 was a cut-out you could open and close from the cockpit. I priced it out when I had a Z-28 myself and it would have been less than $200. for everything except installation.
Anyone have any knowledge about the impact of a cut out on turbo cars?
Thanks in advance for any help, Danno
