New to forum,I'm considering putting headers dual exhaust on my 07 rtl just wondering if anyone else has and did they experience a significant increase in performance and/or gas mileage.

 

Welcome in,just a header and duals wont make that much difference alone. Now if you added cold air intake, larger injectors and a larger cam/cams it will increase hp by about 10-12. Not worth the money in my opinion, these Honda motors are plenty fast from the factory..

 

Thanks bucwheat,pretty much what I expected, was hoping to improve gas mileage mainly.Not really too concerned about sound or being faster.I appreciate the input.
