3" H-Pipe and 3" Flowmasters into 2.5" tailpipes
 

what do you guys think.. Or should i see about getting some 3" tailpipes? My Blue car has NO TAILPIPES and the GAS smell is KILLER so I need some tails. should I go with 2.25, 2.5, or 3" I have 3" from the Header out the Muffler.. BUT i want to Run my slicks too.. they are 10" wide will they RUB the pipes?

i had a 10.5 inch slick with tails and i had no rubbing problems.... you should be fine with 3 inch tails. do you have turndowns? if not, try those first.
