I modded the whole exhaust, 2.5in all the way back to 5in tips. Looks good, I do have a little rasp in the morning when it is cold. But after it warms up, its sweet. I like the SHO-SHOP Y pipe, but would not waste my money. That's my call on it. Of course, I do hate the SHO Shop for other reasons, but do what you want. Modded or not, make it on the Canyon Run. Its going to be awesome. I should have the date by the middle of next month. I will post the date, as soon as I get that schedule. See you all in April. -B.
