straight pipe!

just did a muffler delete on my 5'' exhaust and it is the shit! for any of you guys thinking about it, do it! i was skeptical about doing it at first because i didnt want it to be crazy loud. but it sounds good. i can hear the turbo threw the exhaust and i think my throttle response is better.

the magnaflow did sound kinda quite. i was surprised at how much the baffles reduced the exhaust. it went from 5'' to about 3''. im sure it didnt make much of a difference performance wise, but it is more responsive.

yea the mbrp muffler has little catches in it that would make it way quiter if u put it on backwards but the way it goes it doesnt really restrict anything at. i honestly dont think a straight pipe would do very much at all compared to the muffler

Sweet! Im very happy I straight piped my 4 inch exhaust. I never heard a straight piped 5 but it would be killer to compare them
