Hi Spruce, I hear you but Jason efforts are being hindered by his "BITSA" Exhaust!" Sorry ... just stating facts Cheers ← Geez, just to imagine what the car would be capable of with a proper exhaust The system is similar to any single system, with a 3.5" dump pipe flaring to a 4" inlet/outlet Ballistic 5" body cat, merging back to 3.5" single system with 2 mufflers. I'm sure your comments Just-in are probably not appreciated by Simon from Nizpro, and do Nizpro a real disservice. The only comment Simon has said about my ability is positive, as per his comment in this post http://www.fordxr6turbo.com/forum/index.ph...ndpost&p=458251 Take it up with Simon if you disagree. In the mean time if you can do better, here's the perfect opportunity to show your ability.
