One more reason Cobra exhaust sucks...

[dave85zxt]

Not too long ago I put a stock pipe back on due to sound laws. My warrior had a Cobra exhaust on from the previous owner. It sounded like ****, didn't idle and ran super rich. I always thought that the previous owner put in jets that are too large. Well today I pulled my plug after a few hours on the stock exhaust and its running perfect. The damn Cobra exhaust was more restrictive than stock, causing my quad to run rich. I find it hard to beleive but its hard to argue the facts. I am definitly glad I switched.

yea me too thats weird i thought that the cobra would be a lil more open

The cobra exhaust is way more opened up than the stock exhaust. THere is nothing stopping it. However theres more than a dozen things that could cause that. The reason it didnt idle would most likely be caused by a lean condition.

he said it was running rich tho, but yeah it does seem funny that a straight silencer be more restrictive than stock

It could be lean on the bottom and rich on the top
