mach1basher, nitro completely sucks when you compare it to a gasser. These are by the easiest RC's that I've ever had to work on. And as far as running them, you can't beat it. There's no break in, you don't have to tune once you set the needles the first time that you run it, after that you never have to worry about tuning again. You don't need an igniter or any of that crap. You just take if off the shelf, you can leave the fuel in it from when you ran it a few days ago, so you shake it up a little to mix the oil and gas, flip the choke and pull once, flip the choke back and it will start on the next pull. You can run it for about an hour on a $2 tank of gas if you figure you've got $1 worth of high end 2 stroke oil in the tank, without refilling. Then when you're done, there's no after one procedure. You just put it bck on the shelf, and plug in the receiver pack.
You need to order outerwears filters before you ever run it for the first time. Those are the most important investments that you'll make in RC. The baja is by far one of the most duable RC on the market, and about 10 times more durable than a Savage if you want to compare it to something small scale.
The pipe is a huge restriction. If I were you, I would pull the stinger out as soon as you get it. If you want to buy an exhaust, it will help a lot. This is an excellent site, and they have everything that you could ever want.

If you want to save money on an exhaust, the Baja 5B SS pipe is a really nice exhaust system, one of the best I've ever seen for a stock part. They're only around $90 new, compared to $160 for the Jet Pro, which is a great brand. Don't let the cost of parts scare you, you aren't going to be spending much money at all on this thing IF it's of the same quality as the baja. Some of the clones are great, and some of them will give you nothing but nightmares, so hopefully you got a good one.
This article should help you out a lot.

Seriously, I wouldn't run it wihout the outerwears pull start cover, and they're really cheap
