only a couple of those tips are close
are the same SIZE as the Larger 5" tips included in the Cat Back kit.
...in fact, ALL of the ones pictured in your link are the same diameter as stock
and many are actually smaller ...don't let the pretty pictures fool you...a 3.5" tip doesn't cut the mustard, neither does 4"
The Cat Back kit Tips are 5" Diameter, almost 12" Long, Angled Cut, Double Walled Polished T304 Stainless Steel with a rolled edge.
To get even close the quality/size of the 5" CatBack Tips you're paying Substantially MORE than you would if you just bought the CatBack kit.
The closest ones I've found in size/style at http://www.magnaflow.com/
are part# 35173 (at $215.18 each) but its only 4" diameter
or this one (#35171) that's 5.5" but substantially shorter...for a mere $199.65 ea.
however if you dont "need" high end Doubled walled T304 Polished Stainless Steel,
almost anything is better than those thin puny single walled stocker's
...I think Dodge actually pulled those out of the Caliber parts bin lol!

Ram stock Sport tip
it Takes a FULL 5" Diameter Tip to fill the Bumper Cut-Outs (IMHO)
Shortly after the release of the Magnaflow CatBack kit there were a LOT of Mufflex owners who wanted the same 5" tips for their Ram's.
So Mufflex released a 5"clamp-on tip to satisfy the demand, for $232 (pair)
Too much $$$...but here's the real kicker...it's not even close in quality to the CatBack tips.
They are just a single walled rolled edge tip....a larger 5" version of the stock 4" tips. and look at the inlet size!?! WTF?
