Default Any companies make 3" I/over axle pipe by itself?

I'm redoing my exhaust. Already have pacesetter LT's (those will stay). Going to pick up the texas speed y-pipe with the better merge, and ditching my 2 3/4 I-pipe/over the axle piece that feeds into my SLP dual/dual (which I am also keeping). I don't need to buy an entire catback, I just need the 3" I-pipe/over the axle pipe. Anyone know where I can just get that? Or does anyone know of a cheap catback I can buy that I can use the pipe from?

Thanks in advance.

Dynomax has it for thirdgens, so at the most you may need to make slight modifications at the cat to use it.

I'm using texas speed's ORY....Looks like I could use that one and cut it at the end where it goes into the ORY and weld in a few inches or something.....It's nice to have a friend who welds/works at a local performance shop that will do work for food and beer!

NAPA sells the dynomax I pipe and over the axle pipes. They'll be special order parts but they are available. You can also order an I pipe with a built in dynomax bullet muffler, it's pretty cool.

Imo leave the 2 3/4 piping and just buy an electric cutout set up it will make more power than the 3" piping and you can use it when you want/need, just a thought!!!

The over-the-axle pipe is 3". Didn't notice the I pipe is 2 3/4". Wonder how they connect?

All you really need is 2-3ft of straight 3"dia. tubing, then into a 3"dia. 60* bend which to connect to the over axle pipe.

Dynomax makes the separate 3" I pipe too. part number 54354 is the I pipe with built in bullet muffler, and part number 54064 is the plain 3" I pipe. Pulling this info from napa's pro link online (I don't think the general public can look at this, I'm logged in with my dealership lol).
