CT bypass pipe opinion/question

Jun 15, 2000
Just had them put in on Sat along with CT headers and the car feels better but the sound < 3k rpms is disappointing (5th gear at 60mph and the car doesn't sound very good and feels sluggish). 3k rpm and above and I am in heaven so now I have to drive in a lower gear all the time to get the wonderful sound to kick in. Has anyone with the test pipes put the cats back in place? If so, reasons? I also have the RM DTM exhaust and am having a hard time convincing my gf that the car sounds good this way
