Question about new SBP's pipe?

[toker_ace]

If I just bolt on the new pipe without cutting the header pipe will it increase bottom end or top end? The reason I'm asking is because I perfer increasing bottom end. 30mph face-plant should be plenty fast! LOL!

There's been a LOT of talk about header length and performance - I will say I was more concerned with a good fit than any specific tuning to range, whatever the length it's a great pipe.

It will have little impact on your absolute top speed - maybe 2mph or so, what it will do is get you there significantly faster and your engine will run smoother. Unlike many other pipes, it's not as "peaky" and the increase is more spread out and usable.

I figure cut it to fit and take what it gives ya - you cant lose with the SBP pipe

What Barely said. I got a few more MPH at the top but mostly I like going up hills now w/o slowing down.
