Approved Exhaust--Champ Kart


5506 is the candy cane that goes straight back. 5507 is curved and might hit the cage but it does fit some

Fit on the champ kart is my concern, but is there a performance advantage on the shorter 5506?
No. It moves the powerband up is all. If you're oval racing right against the rev limiter on a momentum oval where you scrub very few rpm, then I prefer the candy cane pipes over the ones that turn behind the seat. For any track that you need a wider power band and more power at lower rpm, the 5507 (or 5511) is a better choice in my opinion.
