Or does the DIY NAPA filter, 4" turbo back and zoodad really make your truck faster. I didn't think I would be able to notice anything really, but I gotta say; either I am psyching myself out big time or my truck was really starving for air and/or constricted! She flies now!

Mine was noticeably more powerful when i did my intake. The muffler delete i didn't notice so much cause i did that with the factory intake still on.

5'' straight pipe must add like 50 lol. To the OP, your allowing more air in and more air out faster, of course its gonna be a little more respnsive

HP Gain no f'n way 1 or 2 at the most, but it is more responsive so you feel a little more off the line.
