Besides the down pipe hump in the ss autocromes i havent heard many complaints about them
I good 3.4 set up with a custom tune and rockers id say you will be happy with the car
then put some into the suspension and you will still be well under 2000
I''ve got SSAC's (XS headers) They fit great and have never given me a problem. I'm probably running a really low 13 on them with no KR and they only cost 350 to my front door.
