Is a 4'' diameter exhaust tip too much for an NA or does it matter at all?

This is the exhaust system which I am thinking about buying...

The piping is 2.75'' which is in between 2.5 and 3'', while 2.5 is the ideal choice between it and 3 inches based on threads i've posted and all the people who responded.
i appreciate the feed back

an n/a adapter pipe isn't difficult to fabricate however the disappointing part really comes from the fact that this particular exhaust is going to make everyone's ears bleed within a 5 block radius. i still run it on my TII and even with the turbo muffling and a borla XR1 welded into the mid-section it is still loud.

You can shape a Turd to look like a Frog,but it still smells like ****!
Nice lookin exhaust but NOT really a suitable candidate for an N/A..first it is an Turbo exhaust,..second.it is gonna be stupid loud,..third,it's too big,so no real gains..forth,well,it's crap!!!

For an na car 2.5" is big enough. With 2.75" ur not going to have enough backpressure and will be boggy under 2500rpm. I'm running a pacesetter long tube header with a 2.5" collector than 2.5" pipe through a resonator and 2.5" through my gp sports muffler ( 7 3/4" round X 14" long with 5.5" tip).
just buy a RB power pulse system....performance with minor increase in noise
