Default Magnaflow for 2009 4 door Sedan?

Hi there! New to the forum. Looking for a cat-back exhaust for my 2009 EX-L 3.5. Seems like the only kits available fit the 2 door coupe. Can the Magnaflow kit for the coupe be modded to fit the sedan?

Anybody have luck with making a system with universal parts?

I want some more power, not just noise.

Thanks all. Mike

Doing just a cat-back exhaust is unlikely to give you any extra power except at high RPM at wide-open-throttle; the flip side is that you might well lose mid-range torque.

I don't have a lot of experience with this. If the systems offer no advantage for street, then do people just install them for looks/styling?

I know that when I had my Harley modified (exhaust & intake), it yielded more performance usable on the street. However, were able to change the air fuel ratios with software.

Most folks do it for the noise or under the mistaken belief a free flowing exhaust will improve performance. If you were to make internal engine changes, software changes, intake changes, and add a turbocharger, then yes, a free flowing exhaust will make a difference.

The thing is, the Honda engineers are very good at what they do and your car is designed to deliver optimal low and mid range torque and very good high RPM power; changing the exhaust tuning will most likely mess up the balance, and while you may gain two or three horse power at redline at wide open throttle, you'll also most likely lose some mid range torque and reduce your fuel economy when driving at moderate engine speeds (i.e. when your're tooling down the freeway).
