I hope someone can help with this. I have been debating on buying headers for about 2 weeks now. I heard from hotshot that they are changing their fit to a flange fit. But this is a what concerns me my exhaust is only 2.25 in diameter because of that darn heat sheild. do I need to squeez 2.5 pipe in there even if I have a dual exhaust behind the axal? Also I bosal worth the extra $100 over the hotshot? I tried to call Paeco or what ever it is and there was no response. Well any advice and input will be greatly appreciated. Sorry for being lenghty.
