2002 Accord SE

[2002accord]

I have a 02 accord se 4 cylinder. I bought a greddy evo dual exhaust. I know thats for the v6 but its for the look when I get my body kit. I was wondering will I lose any horsepower.

i dont know why you would....i have a stupidly oversized exhaust on my GSR and i'm just fine....3" all the way!

The guy I bought it from said he had this exhaust installed on his 4 cylinder accord and had no problems so I was hoping I could do the same.

idk why you'd have problems...

EDITED

Because on a naturally aspirated system there needs to be a small ammount of back pressure. Unlike with a turbo system where bigger is better, there is a point on an n/a car where the exhaust is too big. On an n/a setup the backpressure helps keep the compression inside the cylinder high by minimizing the ammount of flow through during overlap (where the intake and exhaust valves are open at the same time). On a turbo setup, backpressure can lag the turbo's spool up and force the turbo to work harder than it needs to.


If the exhaust seperates the headers so that only two cylinders are used per pipe then you may loose a little hp, nothing drastic but some. If it connects all 4 to a single pipe and then splits it, you shouldn't loose any.
