Riffraff had this and many other products delivered to my house in a few short days, and the quality is worth it. My 3 inch downpipe does everything I need. Reason for the 4 stars is that the welds on mine weren't the greatest. They will definitely do the job, but they are not tig welded. Rather, they are mig welded, and have a lot of undercut. However, the welds are still deep enough that I expect this to last quite a while. As for installation, cut the stock downpipe out, and push the firewall/tranny tunnel out. I got mine to fit by running a 6ft length of 1in square tubing inside, and just pulling as hard as i could. Fit great. Id buy again

can't go wrong

Truck has a little more get up and go.

Does the job at a modest price, fit well.

I read lots of reviews and they all said that any down pipe no matter what manufacture they were from was hard to install. I was able to fish it up into place and bolt it all together with out trimming the pipe or bending anything. I even was able to get the clamp on the joint where the pipes go together with no rubbing. Great pipe Diamond Eye!!!

Have not got it in yet, still working on the firewall. But the pipe itself is well made and of good quality. I don't anticipate it to fail or underperform. If I had the choice to buy it or not all over I'd buy it again.

Very simple task with basic hand tools. Quality sawzall blades make all the difference with the stock downpipe removal. Diamond eye pipe bolted up nicely after firewall clearance was acheived.

Minor tweeking of the seem and fit perfectly.

Far from a simple bolt on job but I personally feel I have the easiest install method.
Clip off wire ties from the heat shield on the factory DP, remove the shields and cut the pipe under the bottom of the truck and then come up top and cut the cobra head of the DP. Watch your metal shavings so not to enter the turbo
Remove old DP
Now comes the new one
DO NOT try to beat your firewall to death trying to push it back for clearance. Simply pull your carpet back on the passenger side and you will see the pinch weld silicone directly under the dash. You will notice three bends (curves) on the firewall. Take your sawzall and cut the middle curve out and in about a 4 inch square... 1inch to the left and 3 to the right. This will immediately give you instant clearance and allow enough room to wrap the pipe with header wrap to help the heat out. It also keeps it from touching the firewall and creating the tin can "drum" effect. Just cover your nasty hole up with some aluminum peel and seel from lowes and reinstall the carpet...your done.
