Nah hes always done my exh work. hell I went to middle school with him. Hes probly done 30 or more exh setups for me. This one just came out extra nice.

As for the duels over y pipe set up. I just cant see a single 4" out flowing a pair of 3". even if its crush bent. As for the exh hitting the axel, I drove it down my buddys shitty dirt road with no problems. It it didnt hit on his road I dont see it hitting any other time. But you know what they say, to each there own lol
