Worked on making a 3" exhaust yesterday. I wish I had some welding skills before I started the project. I had coworker weld up the downpipe and then I gave Adam at S&M a visit to weld on the flex pipe. I may try practicing welding on the left over scrape for the fun of it.
The exhaust has Catco 3" stainless cat, magnaflow chamber muffler. I added a Wideband to it too yesterday. The car is much quieter but has a deep tone to it.
