Got rid of the stock exhaust and cats today and replaced them with Art pipes and Invidia Gemini exhaust. I'd be lying if I said it was an easy swap - cat bolts were a ***** even after soaking overnight in pb blaster. Took my son and me approx. 4 hrs. but it was well worth it - huge improvement in sound and appearance - maybe a little gain in low end torque? All in all well worth the time and $$$ invested in my opinion.

 

Great combo.....i ran it for a year

 

After much searching this site and others your info. and video made my decision to go this route. Thank you travlee.
