I dont have enough to get the presilencer, I have a Bonez highflo cat, and Im wondering if Im gonna have enough room to have it all connect. I dont really know how much farther the RB header is gonna come out than the stock pipe. And I know Im gonna have to have some welded/exhaust work done to make this work.

 

You answered your own question. Yeah, but it'll take a miniscule amount of custom exhaust work.

Is the presilencer really necessary if you are running a convertor? The convertor will act like a muffler to a certain extent.

Just Curious if you thought of that.
