Serious question any CELs? P0402s but to no rear cats. Reason asking bc last Wednesday I got hit by the cat thieves. Little annoyed but found roosters thread and see your a 3rd gen he did. So figured since it was after the rear cats no CELs yea well.

I have had the JFR y-pipe for 3 years now and have never had a CEL. The rear cats are secondary and will not give a CEL. I have also noticed no exhaust smell from removing the rear cats. I did not notice any increase in sound either. The performance increase was definitely worth it to me.

man I wish he was still making them those things are works of art! I read from page 1 to 153 and a few others where he post. But never could figure out what software he used. Any clue?

I would check for an exhaust leak where the downpipe/dump tube meets the y-pipe.

Found a small one last night on the passenger side runner right after the 02 that maybe the cause. Will try to get it fixed today and pray.

Currently, I have the only custom made equal length y-pipe from @Roostfactor for a third gen truck. The following is from a post I made giving my evaluation of his work.

Quote:

Thanks for all of your hard work. I am now on my fourth y pipe since I bought my truck new 3 and 1/2 years ago. I went from the OEM to the URD Mk1 to the URD Mk 2 and finally to the JFR version. After driving almost 1100 miles in the last day my evaluation is as follows:

Performance:

Driving through Oklahoma I had to stop at 6 toll booths which gave me a chance to do 6 wot pulls. I have the OV 93 octane performance tune which has a 6800 rpm red line and I made use of that feature repeatedly. It is very clear that there is an increase in power in the middle rpm range of 2000 to 4000. After that it seems to me that there was no change in power. This is actually good because the URD pipe only gave me an improvement in the upper rpm range.

Sound:

This was my greatest surprise. After starting it up for the first time I got out and walked around the back of the truck and didn’t hear anything. I have the TRD Pro cat back and always heard a low rumble on start up before but now it is so quiet that I had to walk back to see if it was still running. Reving it up gives a very pleasant sound that I have not been able to find a word to describe it yet.

Mileage:

My first tank of gas only gave me 23 mpg which is below average for me. We reset the ECU so I knew that it would take a while to go through the learning process. My second tank gave me 26 mpg which is more like my average going 75 mph on the road. My third tank was a little higher than that but some of the driving was only at 55 mph on a detour around Chicago. I have done some aerodynamic mods such as a belly pan which helps a lot.

Negatives:

The only negative experience I had was the most devious and visceral mosquitos that I have ever encountered. LOL I had 15 mosquito bites on my left arm and 7 bites on my right arm. I wised up a little by wearing a long sleeve shirt on the second day. I don’t know why I had so many more bites on my left arm but they really appreciated my sweet Florida flesh.
Also my body is still a little sore from getting under that truck around a hundred times.

Summary:

After waiting almost a year and driving over 1200 miles from Florida it was absolutely worth it in every way. I would like to thank Roost for his attention to detail. He is a great person who also has a lot of stories of his time in the military. He worked on the same engines that powered the aircraft that I flew in the Navy. I would also like to thank his sweet wife for being so nice to allow a stranger to sleep on her couch.

It may be hard to see in this pic but the 3rd gen auto trannys have a trans fluid heater/thermostat unit attached to it that will interfere with my standard equal length design on 3rd gens.

I hope you're keeping this piece of art polished.

I made and installed these over a year ago, no issues with heat what so ever. My intention was to wrap it, ended up not being needed.

This is without a doubt a master piece.
