Pypes race pros are basically the same as ultra flows, they are a perforated straight through pipe with some packing in the case, cheaper than ultraflows but still a quality muffler, I run them in a 3" X pipe set up on a 500+hp stroker 467.

Can also check on ebay, there is or used to be some brands offering the same straight through type nuffler for very cheap, like $70/pr depending on size. Think it was "full boar" or something like that.

Went with the full boar mufflers at $42 each. Thanks for the recommendation!

Basically the same but half the weight of the Ultraflows..the Ultraflows are built heavy and last..the fiberglass packing may move around after years but they last forever.

They may be lighter, but they are also not as thick of a case so that accounts for some of the weight difference.

Im sure the ultra flows are made a little better, but they also cost more... the race pros are stainless too & will or should last a very long time as well, mine are 10+ years old & look like new with no signs of any problems, still sound like they did when new too.
