I just got my SCT SF3 Xcal flash tuner and had them create 3 custom tunes for me. I just realized that I told them I had an H pipe when I have an X pipe. Does it make a big difference for the tune? I did notice that my flowmasters don't make the cool "baffle" sound now when I dropping from 3 to 2k rpms. Any thoughts?

BTW, this tuner is great! The tunes they gave me cleared the DTC codes I was having. I had a constant "check engine" light since the mods I had were causing conflict with the ECU. Good stuff!

Shouldn't make any difference, its more acoustic than anything else... at best the difference in flow characteristics make for a whopping 1hp difference between the two.

so why do you think I lost the "baffle" or rumble sound in my exhaust? it was part of the fun of driving. it definitely runs stronger now with the 93 octane tune, but I miss that sound.
