Default cutouts

Hello everyone,

I am currently saving my extra change for a future GMMG catback system. In the meantime I would like to add cutouts to my stock exhaust. I have two questions concerning this issue:

1. What average HP gain, if any, could I expect?

2. What is the best brand of cutouts?

Thanks in advance

You really only need one cutout in your Intermediate Pipe before it goes over the axle. There is a perfect place for one there. As far as power gains look for 10+ rwhp over a stock Trans Am or Z28 Muffler. If your looking for an electric cutout I would go with QTP's QTEC. I have one and it works great as long as when closing it you don't hold the toggle longer than 4 seconds and overtorque the gears which then causes it to leak. If not electric our sponsors on the right hand side have all types of cutouts.

I have your anwser --At Street Pro we have put a large number of F-body rides on the dyno--consistantly we see 14 to 18 HP gains with our cutout! Which is best? Check out our web site and then you tell me!
