you won't see much difference in performance or egt's, the biggest thing you will notice is clearance when installing it. Most kit's even the 5" come with a 3.5"-4" downpipe... My opinon is to go with a good 4" kit...

I would go with 4 inch. The 5 inch will give you a deeper tone, but really its overkill unless your running high hp's.

+1 for 4" exhaust... their is no need for the 5" exhaust until you go into the very high hp numbers 500+hp
