I get its welded. Just blows my mind no one makes a x or h pipe that can replace it. IE cut the oem one off and install aftermarket with clamps or weld back into place. I dont mind a full system either but want to retail dual exhaust as I think it looks better. Which options seem to be slim to none for that other than the Europe companies header and reviews are not great on them.
There was, but I just looked on ebay and amazon, and no longer see them.
You cut the cat off, and the new H pipe slid over the header tube.
The H pipe's tube ends had relife cuts, so they had room to tighten, and the kits came with large and wide band clamps.
These were around for many years for the gen2, and I saw them for the Gen3's a few months after they were released.
The listings were confirmed by actual Gen2 and Gen3 pictures(seperate parts, not compatible).
They were around $100
I know this doesn't help much in your search, but I can confirm that they Do exhist.
My guess is that they are not allowed to be sold or listed in many places now due to more Epa rules.
But, never know what turns up on Marketplace or Craigslist either.
People tend to sell oem headers cheap, or give them away if they get a full exhaust.
