I am looking at getting a new downpipe for my car and I have a quick question. The one I am looking at eliminates the front cat, but not the rear cat. I plan on gutting the rear cat eventually.

Will it harm anything to have a much more free flowing exhaust on the front and the restrictive rear cat. Am I better holding off installing the DP until I can gut the rear cat??

Thanks in advance...
