Im looking to change my exhaust from whats on at the moment to a 3" straight through system including decat down pipe. I have heard that providing you use a boost controller and your air/fuel ratios are ok (I would be using a controller) Is this ok? This would be instead of a remap, Ive poured my cash into the handling/suspension so an apexi is not an option at the moment.

Thoughts?? Anyone running full system without remap. My car is a V4 Type r.

 

decat no map anyone but using air fuel controller?

 

What do you mean by Air Fuel controller?

 

one of these Apexi Neo Air fuel controller safc vtec controller on eBay, also Engine Tuning Parts, Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (end time 03-Apr-09 16:05:16 BST)

 

by the time is fitted and set up correctly you may as well pay the extra and have a remap, will get better results and be safer

 

a air/fuel controller like the apexi will also alter your ignition timing! (on a maf based ecu)
