jcole05 Posted September 15, 2011 Share Posted September 15, 2011 Long story short - due to issues with by car and the long turn around time for etuning, I've been waiting for E85 for months (all mods done around April). Still working on 93 octane tune and can't bear any more delays. So here's the deal - id love to quiet my Cobb cbe a bit by adding a midpipe resonator or other strategies than people might recommend. Can I get away with anything without a retune? Let's be clear that I dont mind losing 5hp but mind any possible problems with the car due to different resistance, backpressure what have you.

Bolksey85 Posted September 15, 2011 Share Posted September 15, 2011 You'll be fine. Changing most anything catback is no big deal. Changing from catted to catless or vice versa may have an effect but nothing in the cat back section to worry of. Link to comment Share on other sites More sharing options...
