Are the standard back box from i think the 17 on any good ? , or just go aftermarket. I know it would save some weight but design wise from my stock 2012 one is it worth replacing ?

They are ok, imo dont hold back any power even at 4.25, one of the quickest 4.5 ive been in also had stock rear section and not even a Ti one.

If you like quit and decent flow these are great. Haven't changed the catback on my MY17 and love it.

Litchfield are selling them off at £150 on eBay. I bought one few weeks ago and it turned out to be MY20 was brand new. Just trying to figure out how to operate the valve on my 2011 now.

Edit: just checked their eBay shop and they arent for sale anymore, it’s still worth giving them an email though

This good to know as I think the weight loss would be a good idea, I will look into trying to get one. I am in the North East of England so looking now. i think the valve will be just a 12 v actuator. It may be possible to tag an output from the ECU to auto open at a given RPM.

I’m from north east also yeah it requires 12v but also a PWM signal to actually operate the valve. Me and a friend are currently trying to get an arduino to send the signal instead of mucking about with the ECU.
