Let us know how the fitment goes. Also, do you have the ground effects kit on yours? Might fit better on cars without the ground effects kit.Will

Welded or Bolted.

Not Smog Legal.....For Off Road Use Only.

We picked this one over the Tanabe for the performance gains and not just for looks. Have not even seen dyno sheets for the Tanabe yet.

I don't see any problems with welding the rear cats. Unless they hassle you and tell you that you can't install "used cats". Hope not though. Good luck with it and keep us posted on any new mods.

Btw, make sure you weld the cats in the correct direction. (inlet and outlet)

Here are pics of the same location on the car without the rear cats on the LMS exhaust.
This is where you would have to cut and weld if you wanted to add the rear cats to the LMS exhaust. Not too easy to do since placement is critical to fitment of the LMS exhaust.
Again, sorry for the misleading information.
