Possibly less resistance?

A friend of mine reckons the simplest way to get more power out of an engine, put a decent exhaust system on it.

Default UEL headers, what's the point?

less resistance makes sense as to why Iím doing better on fuel.... I didnít even think of that lol
I think the exhaust would be possibly the only reason why Iíve got more power.

Type ej25 uel header dyno into google and there are a couple of threads on the subject. One topic showed that the car in question lost about 4 bhp around 3000 rpm but made closer to 15bhp up top. The stock manifold is well.......gash!! An ebay uel header and a decat onto a 2.25" system will make decent gains for a na car.

It could be two things:

Less exhaust restriction thus the engine is breathing easier which means more ponies for wheel turning. Or

More noise so you're easier on the throttle, particularly up hills where you're more aware about how hard the engine is working... But really it's probably the first point above

Cheers

Thats why ppl removing catalyst and stuff there. But for mot you must have that stock exhaust to put back on.
Uel is for sound sound sound.well who loves that legendary 95 impreza wrx rumble. Newer wrx imorezas kinda lost that unique sound

Right bit of misinformation here. Even the cheapest ebay UEL headers will add power over the stock header unless you have a ej204 ej253 ie newer avcs motor. The stock headers are ridiculously restriced with tiny diameter short primaries and if you cut one open you will see sharp poorly formed joins that jut out obstructing flow.
UEL headers tend to make slightly less power in the upper part of the rev range compared to the crazy expensive EL headers of TWE/rallitek/cobb but still more than stock. In my oppinion you need to change the full system including decats and a header to see worthwhile gains.

I would say most people wouldnít be able to feel the small increase in hp from installing just UEL headers.... without a nice exhaust to complement it, especially when it changes the way your car sounds also, this might be a distraction.
As mentioned above...even cheap ebay UELís would be less restrictive than stock, and who doesnít like the sound

Thing is we have imagination. Well some more then others, still when you here that subaru rumble sound your brain makes you feel that its lots cooler and more powerfull. Similar to cold air filter mod it gives so much sound from air intake , even too much for daily driving. Uel alone is enough here.

If you just installed UEL headers with stock exhaust system would you still get a rumble? Assuming it would be a quiet rumble but still more than what you get from the stock headers.
