no its not....the coupe is 280/280...same as '04 then '05 is 290/260

the '03 sedan is RATED at 260 but put it on the dyno and u will see its also 280.

huh???
I know my Sedan is 260hp at crank not 280

sedans have 260
coupes have 280

you are correct 03 sedans have 260
03 coupes have 280

yeah i editted....but the 260 rating on sedans was just marketing for the coupes....the only difference is the midpipe but thats not a 20hp difference....plus the sedans are lighter (which only matters for wheel HP)

so actualy i do have 280 at the crank then?

prolly like 270/275...but get the coupe midpipe and u will beat ANY stock coupe

Hmm whats the differance on the midpipes? Is that the pipe with that big *** resonator?

I dont remember what the difference is...the sedan's might have an added resonater or it may just be smaller in diameter....

there are a few good pictures of the pipe with a huge resonator, it scares me just looking at that.

so there u go....switch em out and its amazing the difference in both sound and torque off the line

You'll save about 25 pounds by replacing the sedan midpipe with the coupe midpipe. It's a direct swap.

How about just removing the resonator?
I already replaced stock muffler with some stainless steel no name brand, i know it weights at least 15-20lb less than stock.

i dont think u can just remove it....i think it the center and pipes are welded to both ends of it....removing it would leave about 2feet of "nothingness"

the coupe one also has a resonater but much smaller.....u could get testpipes if u dont want a resonater at all

I meant replacing it with a smaller one, like a straight truegh glass pack or something..
