What size is our stock DP? 2.5"? Im just curious because Im seriously considering ordering CIA's stainless catted DP tomorrow, because of the great sale right now, and Im wondering how much better this would be for my car. Are our stock DPs that restrictive? Do you think I will get much change in sound with just the DP and stock cat back still on or will it still sound stock? What do you guys think?

 

Stock is 3" rescricted, CIA DP will flow alot better and sound alot deeper at WOOT. You won't be disappointed!
