I have a 07 TC with the usual magnaflow Cat Back, Ingen intake and a Strup header. I really do not want to add forced induction is there anything else i can do for power ? Is a mid pipe a good idea how about some kind of programmer like the JET or a UNI Chip and Non Stop tuning pullys the car is really for car audio but MORE POWER is always good !!!!!!!!!

most everything bolt on will be marginal gains, save for boost, pulleys will help a little with quickness but suspension will make it more fun, do springs

I have eibach suspension on the car also and 18in wheels and tires

sway bars, underdrive pulleys

Weight reduction!

haha kinda tough when your car is mainly for audio. "should i rip out the back seats and keep my 12' subs?"

How about take out the rear seat and ADD more subs lol, you did say it's for audio. If you're into racing, autocross, road course, w/e go for a removable setup if possible. That way you can drop the weight at the track.

I agree, however, the most reduced weight I found was some light weight racing seats. I have myself a set of corbeau forza (20lb each), and I felt a big time difference. I think only delete the rear seats won't help alot. But I did both. :P
