Quad with stock exhaust
 

Okay Im just wondering but how much power is being restricted by my stock exhaust and can I do any damage to my motor running my quad pulse v2 on level 2 with the stock exhaust? Im working on buying a 5in straight pipe. full exhaust soon.

If you keep it on pl2 you shouldn't notice anything but slightly higher EGt's. Keep it below 1250 and you'll be fine.

A good free flowing exhaust is good for a few HP, noting super noticeable.... But it will definitely help with efficiency, EGT's, fuel milage, etc

X2 on the above posts. Power difference won't be noticeable, but the gauges will let you know its breathing better.

Wouldn't hurt to put a muffler on that 5". It will reduce cab drone, but still bark out the end.
