Hey guys, I currently have a VF2 SSV LS3. Was supposed to do some upgrades last year but was away overseas in Greece and got back about a month ago. Currently have a custom tune + otr. It went from 208rwkw to 246rwkw & from 542.4NM to 596.1NM torque. I see alot of people with the same car are getting full exhaust systems with a tune and otr resulting in 295-300rwkw. Im looking to upgrade my exhaust to a full exhaust with either 1 3/4 headers or 1 7/8 headers along with high flow cats & 2.5 inch cat back with bimodals. Correct me if im wrong but i cant see how im going to achieve a 50rwkw gain to reach 295rwkw with upgrading to a full exhaust and retune. Is it possible? Im looking for more bottom end torque and more responsiveness so are the 1 7/8 headers ok for that or should i go 1 3/4?? I hope there will be decent gains cause cost is close to $5k for full exhaust & retune.
