you run 16s with a qjet 305. there is no reason whatsoever to buy a 4" exhaust.
but if you must, the only issue that comes to mind is clearance.

The problem that your going to be looking at is that the system is not "bolt on". It sort of is but if you just put it on with everything that is supplied, you will have major groud clearence issues. The system tries to use the stock hangers for one. Bad Idea. If you get the sysetm, take it to a good exhaust shop and tell them to do what they have to do to tuck it up nice and tight. My shop only had to make 1 cut, install 2 custom hangers, and then weld it. Mine sits nice and tight and you can't even tell there is 4 inches of sewer tube under the car. Good luck.
Hope that helps.

OK, and yeah I know 4" is overkill, but there are two for sale for around 350 which is about the price of a 3". When I do start making this fun it can't hurt to have the extra inch of volume.

350 is a lot of money for a thirdgen cat back. You can have a Hooker cat back for 150 less and still have enough exhaust to support 400hp+.
