[QUOTE="XP900, post: 16546757, member: 199546"] Don't know what your mods are but the 13 stock H pipes with the stock Cats that I bought (practically new from Alibi2) are 2.75 at the rear and all the way from the cats back. From the manifold to the cats is 2.25 which I think is the same on 2010 - 2014 and probably the previous years too. From the mid pipe you can use the stock pipes and mufflers for factory sound exhaust or others. I am trying to use factory mufflers with a Lethal Performance over the axle since it costs the same as factory when on sale. Don't know your mods so I can't compare to mine. I simply want to decrease my boost due to what seems to be exhaust restrictions on factory exhaust. I read 750 engine HP is the max for 2010 exhaust to handle and I am at that mark probably causing my boost to go up at the higher rpm over 5800. If you go back to stock 2011-2012 or the 2013-2014 mid pipe and have no leaks I would think that alone would fix your smell or fumes. Noise would be determined mainly by what route you choose to go from mid pipe back. I have a 2010 with mods but your numbers are probably slightly higher than what I originally had on my stock at 200ft above sea level before any changes. My car has 43K - not abused or tracked so they are good miles. [/QUOTE]
