Yer cheera guys! Yer cat back sounds like the plan and the actuator. Yer if ya get one in like new condition wif 60,000kms id pay the 25k. But u can get them even cheaper then 25k I assure u 😉. As for boost im on 12psi atm, I think I have a very conservative tuner, but yes I think ill go cat back / actuator first. I thought a fuel pump prob be good till like 330rwkw maybe?
