What's the deal with customising motorbike exhausts onto cars?
I've heard all the rumours saying that they cause back pressure etc that will blow up the engine but that can't be true can it.
I'm toying with the idea of having 2 motorbike exhausts coming out of either side of my custom GSI bumper on my manta.
Manta has a 2.0 SRI 130 (SEH) engine. What are the risks of using them on a car?
they look stunning
I dunno how much power increase they add??? Might even make it slower, anyone done this?
