Was it a bear...yes at times because I had not done this before. I spent 4 hours doing the drivers side first.....quite a bit of time talking about it's "Mother"

If you decide to do this make sure you get the pipe in place and attach the end to the muffler coupler first....I mean first or you will never get it to go together. The angle is so great you cannot pull the pipe back far enough to slip it into the coupler if it is bolted to the flange first. Bolt up to the muffler and leave the clamps loose, then bolt up the triangle flange to the cats and tighten, then go back and tighten up the couplers.

After I completed the job, cleaned all my tools and put them away I took it for a drive. The sound is a good bit deeper and meaner when you are at 6K , the transition to idle where you always get a bit of drone is deeper and better.

It revs up noticeably faster and I can tell a slight improvement in power. The pipes are huge compared to the pipes on the secondary cats. I could not believe how much the secondary Cats and heat shields weighed.

All in all this was money well spent IMHO as they still have the kit for $150 for members of this board.
