How can i cheaply create more back pressure on 96' 2.2 Cavalier?

this is a first for me, normally people want to reduce backpreasure.
I miss my Sunfire, I want it back!
MMMM, HIDs
You will be missed.
Answer the question guys....
stuff a rag in the muffler.

Here is a post I made in another thread:

In a perfect world you would have an infinitely small amount of back-pressure, and an infinitely fast exhaust gas velocity. This is part of the reason why people wrap their exhausts. It is not necessarily to keep under hood temps down (although that is a plus), it is to raise velocity. Hot air weighs less than cold air, so it moves quicker.
As an example of this: when Joe Shmoe puts a 4 inch cat back on his civic and complains that he lost power, it isn't because he lost back-pressure. It is because he los exhaust VELOCITY.
It really comes down to what you want your car to do. There is such a thing as too large of an exhaust, or too little exhaust velocity for a given application.
So, you don't want to gain back-pressure, you want to gain velocity. Your best bet would be to keep the stock exhaust if you want all your torque down low. However, it WILL choke out on the top end, and therefore be slower overall.

That crackle you hear is usually unburned fuel in the exhaust lighting-off as it mixes with outside air that gets sucked-in between the pulses when the engine is winding-down after the throttle is snapped shut... It'll happen on any car running a straight-through exhaust with a rich fuel mixture. Glass-packed carb'd engines do it naturally, and I'll admit... it does sound cool. But on a 4-cyl with a fart-can, which already produces the most annoying exhaust-note known to man, it'll make the car sound even more obnoxious. At with point you might as well add a ludicrously powerful audio system made of nothing but sub-woofers, and continuously play a track of random low-level bass notes everywhere you drive. Geez....
Go beyond the "bolt-on".
