LX 177 hp Vs EX 190 hp

Does anyone know the difference between the two configurations?

It seems like its the same motor, but one has the higher HP...

prob just the way it was tuned. no physical difference - or maybe theres a different manifold on it or maybe a different cam running each engine...who knows there are endless variations that can change the amount of HP an engine has - but i think its just the way it was tuned.

if you rev the LX model as high as the EX model you'll get the same power :3 J/K probably the tuning.

The EX version has a freer-flowing exhaust system and, as you guys said, different tuning and a higher redline.

On a side note, the EX's free-flowing exhaust system apparently drones at low rpm, which is why Honda equipped the EX and EX-L sedans and all coupes with ANC (Active Noise Cancellation).

You are right. Mine sounds very similar to the 2004 TSX my mom had at one time. It more tone than a stock SI too i think. I carries a tone similar to my 5th gen. Prelude.

190 Horsepower 2.4-liter Inline 4-Cylinder Engine (EX, EX-L Sedan; All Coupes)

Overview
The 2.4-liter inline four-cylinder engine that powers the EX, EX-L Sedan and LX-S, EX and EX-L Coupe is closely related to the engine in the LX Sedan and LX-P Sedan. The 190-horsepower inline four-cylinder meets ULEV-2 in all states, and PZEV (AT only) emissions standards in select states. Like the 177-horsepower engine, the 190-horsepower engine's PZEV variant has single exhaust valve operation at low rpm, dual-probe electrode spark plugs and special PCM mapping.

The key feature that allows this engine to make an additional 13 horsepower and 1 lb-ft. of torque compared to the 177-horsepower four-cylinder engine is a special exhaust system with larger diameter tubing and a variable-valve silencer design that nets a 31% increase in flow relative to the previous generation Accord four-cylinder system. Despite its performance advantage, this engine delivers the same EPA-estimated 21/311 City/Highway fuel economy (Sedan AT) as its less powerful counterpart. Inside the interior of 190-horsepower Accord models, an Active Noise Control system (ANC) helps reduce certain undesirable sound frequencies for greater passenger comfort. (Please see the Interior tab for more information.)

so does this mean that upgrading the exhaust of the LX/LX-P would give an increase that will net to almost the same power as the EX?

probably.
tuning and gear ratios still give it an advantage.
