im switching from an ory setup to a td setup it will have an h or x pipe with 1 chambers...

just wondering if im gonna gain anything at the track.....im mainly doin it for the 1 chamber sound but if im gonna gain any et that will be great...

 

oh it will all be 3" and dumped at the axle

 

I saved about 30 pounds going to the true dual setup and pickup around a tenth at the track. Currently I have a totally stock bolton car, but it is loud inside the car. At first I did not like it, but I got used to it and I like the new time I was running at the track.
