I would assume a little low end response may be lost though... Link to comment Share on other sites More sharing options...

Guest Guests Posted 09/11/08 02:11 AM Share Posted 09/11/08 02:11 AM 3" hotside piping is overkill unless you're going for 500rwkw+ mate. Nizpro's stage II kit retains standard hotside pipes & is good for 380+ at the treads Link to comment Share on other sites More sharing options...
