Well my first mod is underway. I have a stock up/pipe in the mail that I am going to gut and (hopefully) successfully transplant. Now for the down-pipe. Are the stock units gutable? I will find one if this is the case and gut. Thanks
The stock uppipe can be successfully gutted and will be as good as an aftermarket one. While you *can* gut the stock down/mid pipe they will still be more restrictive than a proper aftermarket one though.
