anyone notice this. i know it's hard to keep your foot out, but just a question on peoples experiences with catless downpipes.

it should go up by a mile or two per gallon. coupled with a PROcede its more like 4-5.

I haven't noticed any real change, but that could be because I have my foot in it all the time since I put on my DP's
