Not sure what exhaust would suit you but if your using it to bang out tonnes of miles do you want it louder? Save the money for tyres or something. Just my opinion however.
I would rule out your headgasket first but its entirely up to you. Changing a rad cap isnt gonna cost the earth though so why not, im sure subaru put a 1.3 bar cap for a reason. Hope it works for you mate 🤞
I know the thought of this sucks but if i were you i wouldn't drive it until you get it inspected for Headgasket. Last thing you want is regular high temperatures it will cause a chain reaction and for a week or so off the road you dont need that headache.
My bugeye had overheating issues which was cracked radiator aswell. Found that out when there was big piles of steam coming from the bonnet on the motorway lol
Thanks for that man thats good to know. Hitting a brickwall is exactly how it felt spot on there
I will definitely have a talk with the mapper before hand and make sure that stays in, want to make sure he doesn't go for max boost anyway .
Ive not had it mapped yet mate and it does have a sports cat aswell so might be overboosting. Would the ecu cut the boost in this case?
Just waiting on a hose coming from subaru for oem recirc valve then its in for mapping 👍
