Ok thanks hey let me know what tuning it does for it,I've been wanting to do that on mine.hoping it will help on take off,I think my top end acceleration is ok but I'd like a little more take off and no govern would be nice

According to Pypes the Catback Mid Muffler system adds 5 to 10 hp. The gain is only slightly noticeable in the upper power band, and that is to be expected. When I install the supporting mods of long tube headers, shorty x-pipe, and a tune then I will expect a bigger gain. Because if you put long tube headers and a shorty x-pipe on your HP gains will be reduced because of the rest of the exhaust from the cat back is still restrictive. But lets not forget the sound, the exhaust system is worth every penny in the change it makes in the exhaust sound alone. Hope this helps.
