Re: Exhaust size?.....

dont go with flex pipe, you want a nice smooth flow, not a pipe ith ripples all over. and Id go with 2 1/2

my buddy's dad owns a muffler shop and he told me that even on my 1.8 liter 2.5 would be fine, a little on the big side but wouldnt affect teh power noticably at all at the botom end. seems like a 2.2 would be a sufficient jump in displacement to justify the 2.5"
