This may belong in exhaust, so sorry if I'm in wrong section. I am contemplating getting rid of Bassani x, and Catback for stock setup. I don't like the exhaust to loud. So how many hp can I expect to loose?
Just weld stock mufflers or Borla 14858 in the Bassani pipes. You want the mandrel bent tubing and that's where some of the horsepower is, plus the 2.5" vs 2.25". You are not going to lose too much, guesstimate 10hp loss welding in stock mufflers? The 14858 sounds nice, deep bass but not overbearing. Probably would not lose any hp with the Borla.
