Look now, u acting like a pro,,,sigh. Listen, i play 1.3, 1.5 stroker kits before, what you experience i know, i even change my exhaust set 5 to 6 times to get it right. The most suitable piping is still 1.5 inch,,,,1.8 is wayyy to big. If you still satisfy with your 1.8 inch piping than up to you lar,,,,,he he.
