Pipes to consider.....

RB/Nova 2630, but you need to match this pipe with the right header. Don't be too scared to get one of these.

RB 2604 is another good choice as is the 2611, which is a sirio based pipe.

Once again, knowing where you shop speak to the boyz about an ATS pipe. Cheaper and it will provide you with some good results considering how much racing you do and the motor you are purchasing.

Hope this helps.
