Stock Exhaust Interchange

[IndianRob]

List -

I just purchased a Blaster with an aftermarket exhaust system and I need to make it as quiet as I can (it will be used around horses). Based upon the comments I've read, the quietest exhaust is the stock setup (am I wrong?). My Blaster is a 1990 and I've found a 2006 exhaust system for sale. My question - will the '06 exhaust fit on the '90? Also, I suspect I'll need to re-jet back to stock as well. What jetting do I need?

Thanks for your help.

All the stock exhaust systems are the same so yes it will fit. If it is COMPLETELY stock other than the pipe, then you will need a 230 main jet. The quad will be a lot slower though with the stock exhaust.

Guys -

Thanks for the help. I know this is a terrible thing to do to a nice Blaster. If someone comes out with a truly quiet aftermarket exhaust I'll install a set.

Please let me know if you are interested in trading or selling your old exhaust, I have a complete factory setup.

I appreciate the answers but they raise a new question: With the stock exhaust installed, can I increase the jetting from the stock 230, would it improve performance and, if so, what would be the best jetting? Thanks. Rob

(I've already purchased a stock exhaust system and I'm going to hang onto the aftermarket system for now but I appreciate the interest in trading exhaust systems!)

You need to read up on how to take care of your Blaster so it can tAke care of you. Learn: plug chops to check jetting, leak down test.

Jetting is what controls how much fuel mixes with the airflow. Increasing the size of the jets will richen the mixture, but if you haven't increased the airflow or combustion tendencies within the engine, it will just add more fuel to the same amount of airflow you had before. The end result is you have uncombusted fuel that is essentially just wasted and you will decrease performance causing it to sputter and run slower. The overall goal is to have the ideal fuel amount with the amount of air you are flowing........this is what leads to efficient combustion inside the cylinder. Too much and you are rich and slower. Too little and you are lean and overheating and generally running slower as well. Point?........No.....increasing the main jet size won't increase your performance on a stock engine/exhaust/filter/etc.
