They do not have to be welded. I asked Adam at Riss Racing and he said that these pipes are slip jointed to your stock system so there is not welding necessary.

Im pretty sure you have to cut it then either weld/flange/couple it.

Does the stock exhaust have to be cut in order to install these pipes, or is it a true bolt-on?

"Basically these are installed by cutting the stock pipes about an inch or so after the secondary cats. You must remove the exhaust and have a slip joint made with rivets. Then reinstall on the car and clap the RR mid pipe into place. You may also weld a small section of piping onto your stock pipe that you cut off so you can interchange the two. Adam at Riss Racing also said per e-mail "They will slip inside the stock piping so you do not have any leaks. When lining them up, make sure the muffler/exhaust shop leaves enough room on the stock system so you can slip joint these inside. That is crutial so there is no cut/welding necessary. " Hopefully this answers your question. |

Sorry, I have no way of confirming if these will pass smog. All I can say is these pipes can be easily installed and taken off as they slip-ons, so down the road when you car needs a smog check you can put back your stock 2ndary cats.
