c'mon Steve, don't be a lazy a---e! It 's car up the stands, 8 bolts each way, disconnect and reconnect the sensors, car down and only once a year
I will do it for extra ponies anytime and save more good change for other mods. The evo/ scooby/RB crowd are at it so why not
Have you ever changed the cats over then Bennet? I doubt it I paid a garage £60 to swap over my standard cats for some HKS hi-flows, and even with all the tools on hand, and up on the ramps above head height, it was a bugger of a job
If your car is purely for the track then its a viable option, but as you use the car day in day out on the roads then it aint worth it.
You'll more than likely have to do a reset every day, due to the engine check light coming on all the time.
The car will be technically illegal to drive on the road, and if you had an accident and the insurance company picked up on it, you'd be fooked
My car ran lovely with the hi-flows connected, it also flew the MOT, no issues whatsoever. I wish i had the car now with the set up it did have, and taken it to RS-Tuning to show you that hi-flows can give just as good gains from a reflash as decats.
In summary, its against the law and too much hassle for similar gains to hi-flows.
