but what about the bolts and springs?
why are they needed?
Right the bolt and springs are a system to keep the collectors and pipes together , it's bit of a **** system as they don't do the best job , but saying that these are long tube headers and needed a lot of work to fit as you cannot fit them in 1.
The best headers to get will be kleemann which I have had before but the long tube headers are good to get a bit more bhp out of them.
It sound like a monster there are no cats at all and I am running 3" pipes which is the biggest I have ever ran on the car.
