I have a '04 that I swapped out the srt6 drive train with 3' dual cai and sc pulley and some other mods. Never had a bad feeling about going 154mph (as fast as I have gone) And it had more in her just didn't have the road to do more. I like the fact I have a stock looking NA with all the srt6 brakes and suspension to go with the drive train. I too do not like the "whale tail". just my .02 I really like it when a STi see's my tail lights and don't know what hit him ....same for a few Beemers it's fun because the whine of the sc is the ONLY indication mine is not a stock NA.
