I run true duals on the street and i have heard of peeps putting bullets on the headers im curious is there a gain by just running open headers at the track i know it will be loud as **** and sound like **** but im just trying to squeeze all the performance out of my car i can and save a lil more weight while at the track.

 

I would suggest you run a section of pipe after the headers about 10-12" long for the 02's.

 

Just get an electric cut out or two.. My cat back is so bad i gain 30hp when opening my cutout. my boy who has his stock centermount catback only gains 5hp.

 

I have a sd tune 02's are deleted

 

I'd open it after the X or H, if you have one...
