I plan on keeping my engine stock. Just the normal bolt-ons. Headers, X-pipe, smog pump delete and pulleys. My question is the HP that much of a difference. My car is a weekend/Sunday driver. I'm not concerned with squeezing every once of power out of it. http://www.uprproducts.com/shopping/shopexd.asp?id=2046 has a nice set of stainless shorties for $179. I like the way they look and they have great service so I want to buy all I can from them.

You wont notice much difference in power. Just remember the equals are going to take up more room in the bay and be more of a bitch to install.
can you elaborate, ryan? difference ? from stock, or b/n the two types of headers?

You might see a hp gain or so from using equals over non. I don't see how they are any harder to install then unequals i had no problem with my bbk equals didn't have to lift the engine or anything
I have never installed them myself i have just heard of people having some difficulties. I personally just don't see what justifies the extra cost. He said he was not interested in squeezing every inch of power out.
Basically what you're dealing with a cost/benefit analysis -
Regular shorties are FINE for stock applications. They dont (usually) require changes to the h-pipe/cats, they're (usually) easier to install, and they're cheaper.
TUNED shorties are more commonly used in applications where the owner is trying to squeeze more ponies from the engine.
Tuned shorties use primaries that are equal length, and, as such, cause the exhaust gas pulse width to end on a node, rather than an anti-node/mid extension. This helps with exhaust gas scavenging.
Shorties used without a complete air tract (intake, heads, headers etc.) defeat the purpose of tuned headers. As the air/exhaust speeds up and slows down as it moves through the motor it kills the positive linear acceleration curve that would otherwise be obtained through the use of a polised system.
if your buying new, i dont see why to spend the extra on equal..i got mine from a buddy, they werent hard to put on so dont let that be a reason of not going with them..but regular shorties are gonna be cheaper...n still better than stock kinked/dented pos's...
Get the shortys you have listed. With the stock engine you won't see tremendous power gains with the long tubes and you say you plan on keeping it stock. Less hassle this way and a decent upgrage over the stockers. Running a stock 87 engine you'll be fine and may pick up a few ponies.
