yea the price on the 1 3/4 went up after i bought them. so the 1 7/8 are cheaper now, but if they will flow better then i think i will keep them and not say anything based on the previous replies, would there be anything negative for having these like the sound or anything

If you're interested in peak HP then they're good. Bigger isn't always better and on a less than 500 HP you'll be losing below peak. I shake my head every time I hear "flow" like putting on the biggest pipe is always the best thing. Below peak in a large pipe velocity gets lazier and it's that velocity that makes a header work. A lot of people should do some reading of exhaust theory that isn't on a forum.

****.
That's exactly what I'm so sick of hearing. The #'s don't lie. The only, and I mean ONLY graphs I've ever seen with a loss were from a C5. And that's more due to primary length than anything else.
Is this where the conversation get's turned into "Is the FAST 102 too big for stock cubes?"
