2 1/2 or 3 inch exhaust

I"ll be needing exhaust from the headers back soon. Still looking at the pro's and con's of both 3" and 2 1/2". I'm stuck between will a 3% reduction in HP (roughly) be worth it? My main question is does someone make the "machine gun" tips for a 3" exhaust for a 71 RR?

I bought PYPES EVT89 Stainless Steel Tips for around $150 last year. Fit in the hangers fine on my 74 Charger but don't stick out much beyond the valence panel, maybe 1" or so. Would have liked them out a little further but great other than that.

Pictures?
 
They look a little better when I clean them up a bit, but here they are after a year. I put them in the stock exhaust mounts but would put them out a few more inches if I did it again. I didn't mention that a previous owner put a dual cut out valence panel on there, which I don't think was available stock on the 74's.

Never heard of Pypes. Have a web site? Also, what are the overall length of those you have. Don't remember but they don't stick out that much from the valance panel
 
Thanks for the post but ran out of time looking for tips
