Evenin Gents,

I'm wanting to get a catback Blitz Nur Spec RX for my 2007 STi non PPP. Because this is catback and non lambda invasive would it be ok to do this without a remap or will the slightly higher flow cause an issue along the lines?

TIA

 

Cat back doesn't usually present any problems ECU or map wise. Although to extract the performance it would be wise to get the car mapped.

Hope this helps,

Graham
