Hi. I am a new Harley owner and new to this forum. I recently bought an XL883N Iron. I love it! I want to do a stage 1 conversion but the options are daunting and I can't find any real data on the performance of aftermarket parts. I want performance but I don't like the look of the 2 to 1 options for sportsters. I've been told 2 to 2 exhausts decrease performance over stock with slip-on's. I am considering going with V&H double barrel or the BUB Lakester or Straight Away (mid or long) with a SE Air Cleaner kit. Would these options (or any) provide better performance than slip ons or is it all just theoretical? Any help, whether technical or experience would be greatly appreciated!
