Default Uel headers?

Hey I am about to buy unequal length headers off of a 2005 n/a impreza. I have a 98 legacy gt with a 2.5" borla cat back on now. What will the uel headers do (negatively and positively). Please help soon I am getting them tuesday.

UEL headers are what give the boxer engine the low rumble that many love and some don't. It's rumored that there is less power to be had in UEL headers, but I haven't seen proof.

There are gains for UEL and gains for EL both are minimal. EL is more room under the curve (the dyno plot) UEL give a peak under the curve but not as board a range. The thing to remember is if your motor is stock it doesnt matter neither will get you down the strip faster and one will make your car sound like a honda.

Hell yea it will. You have to buy a test pipe or high flo cat as well. I have borlas, Rallisport high flo cat, greddy ti-c cat back. I tell you what my car sounds better and louder than a wrx/Sti. I spent alot tho but so far it has been worth it. There needs to be a 2" piece of pipe welded into the exhaust to fit

For sure get the UEL headers if you want it not to sound like a civic.
