I am looking to verify that the FMF Powerbomb header does in fact allow access to the oil filter without having to move the header pipe. I have a gift cert for a discount on one but if it still blocks the oil filter then I don't want it.
It does not block the oil filter access, I have one on my '98 400.
The only problem I had was no heat shield. But......the stock heat shield will work on it, but you have to spot weld a couple of 6mm nuts or the stock mounting brackets.
