Thinkin about going back to straights.... still. only difference now is that im about to put a hypertech on. by going from a maggie di/do with no rear cats to straights with an x and a hypertech, am i going to lose any power or tq or mgp? I've heard going from maggie to straights is okay and you dont lose any power or tq, is this true?

 

Mufflers have nothing to do with tuning, well, if chambered sometimes they do, but generally your all ready running a straight setup since Magnaflows are direct flowing, the only thing you should do is get an X pipe after the delete.
