[QUOTE="vanderchevy18, post: 60319, member: 569"] I get that. Good point. What I was thinking is that there are a few bends from the down pipe back to the stock exit. I am going to go with 5" just before the 90 going from vertical to horizontal at the bottom of the down pipe. The thinking I have is, each bend in the pipe slows the gasses during redirection of flow. By increasing size, the bends shouldn't cause quite the backpressure. I already ordered the kit. If for no other reason than to keep from smoking out the other lane during staging at the track and keeping in accordance with pulling rules. Its really no big deal to do some testing to see if there is any side effect from doing it. Thoughts? [/QUOTE]
