"Sixfive - don't forget that a slightly modded 6MT will beat a slightly modded AT. You need to compare apples to apples. If I add that same plenum, z tube and light exhaust mods I can easily beat the 05 auto and 05 stick. Actually I will be very egotistical and say I could beat the 05 auto without any mods to my 03 6MT. "

Yes but there's less repsonsiveness to mods as you reach the limit of NA potential. You are correct but I've noticed that most modded AT's respond better and start to perform similarly to modded MT's. At 300 or so you hit the wall and we all can get there..and then if you can lauch yer in the 13's.

The wires do little for the stereo more of a tranny thing and it smooths out the idle and such. My best mod is the Plenum for sure. 15 hp and I say 20 on a AT sedan...

The polks are the best interior bang for buck I have performed. They change the front seat sound drastically and for the better with little install time and for 60 buks!

Did you have the premium sound or the regular. I have the regular and was thinking about adding an amp plus sub into the box that the premium sub would be in as well as just the front speakers (Polk has very good price for performance in both car and home audio.. good choice). In your opinion and could only pick one, would you do the engine mods or the stereo mods. I'm leaning toward the stereo only because hp and lb/ft are addictive and once you start...
