Are you currently running nicely swept fittings like this: http://static.summitracing.com/global/images/prod/large/aer-fbm3156_w.jpg or hard 90's like this? http://static.summitracing.com/global/images/prod/large/aer-fbm2037_w.jpg It's entirely possible to see a decent change by going from hard 90's to swept fittings. No drilling, tapping or otherwise rerouting anything. Pat
