400EX 2-inch Performance Exhaust Insert

[jt29]

I found this 2-inch exhaust insert on ebay, made by Phoenix Spark Arrestor. It says that you will get 10-15% power increase over stock when used with the recommended jetting and no airbox lid! (jetting recomendation for 400ex only) Has anybody used this or know anything about it??

Waste of money. If you want just take your lid off, take out your baffle, then rejet.

Anyone else?

Seriously its not worth the $40-$60 your paying for it. You can have the same effect by taking your spark arrestor out and taking the air box lid off. You probably wont even notice any of a power difference from it. A kid down the road from me has one on his and it sounds like shiit and is extremely annoying to hear him ride by all the time. Save the money and buy something better.:)

Waste of money. Just remove the baffle and lid and then rejet accordingly...

just save up for a full exhaust. IMO the stock pipe without the baffle out sounds like poopy
