horsepower question
Be nice ... I sort of remember weighing 120lbs, I think I was in 7th grade or something.
The bottom line is both cars are slow as hell, so why even bother discussing this? Oh, and being automatic doesn't necessarily hurt in a drag race if the tranny can keep up with the horsepower and the driver knows how to make the computer shift. A friend of mine with an auto Maxima was killer at the track because he had the feel for his tranny down pat.

His fartcan may give you a distinct advantage. Excessively open exhausts generally do more harm than good. The problem is they reduce the low-rpm power by ridding the exhaust of the much-needed backpressure. They do afford the benefit of yielding tippy-top end gains (if any) Here, take a read (skim down to the exhaust section): http://www.pumaracing.co.uk/gentune.htm
The "best" aftermarket exhaust on the 4cyl lost only 1hp over the stock system.
exhaust has been discussed to death. The threads are old (early 04?) but they're there and this is a wheel that's not worth re-inventing

why does the site say " Every system cost at least twice as much as the standard one and the BEST of them gave 1 bhp LESS than standard." (http://www.pumaracing.co.uk/gentune.htm)
so aftermarket exhaust on a bone stock engine makes it worse?

Yes, a catback exhaust on the stock engine in question opened it up too much. For the lancer it could be different, but the general rules still apply, you have to design your exhaust for the nature of your engine, whether you need more back pressure or not.

Beware also of magazine tests that don't use a brand new standard system in a back to back test with a performance system. Because that costs money they usually just test the car as it comes for the "before" power run. If the standard system is already 5 years old, nearly rusted away and with silencer boxes clogged full of carbon then of course the performance system shows a gain - but so would a brand new standard system. It's not just "performance" systems that can be a waste of money. Some of the aftermarket standard replacement systems can be pretty dire too. They might look similar on the outside to the OE system they are designed to replace but have poorly designed silencer boxes that kill the flow and power stone dead.
Big bore systems can even hurt power quite a lot, especially at low rpm. I've fallen into that trap myself in my younger days. The OE manufacturers spend millions of pounds and several years in testing and development on their engines. The "performance" exhaust system manufacturers weld a few bits of tube together and spend a couple of grand on advertising. Who do you think has the best chance of getting it right?

okay, if this is the case, then why are ppl always talkin about HP this HP that, buy this intake, muffler, etc etc to increase HP? Not to sound like a dick, i'm just curoius....how do u incresae the Torque then?
For one, the 4g94 intake manifold has longer runners, which helps increase low end torque. Thats one of the differences between the g93 and g94.
With that, would it be safe to say that our IM with a larger bore helps increase torque?
