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.

This isn't some gimmicky part that is charging you for the makers name, it's everything you need and nothing you don't and it makes a hell of a difference. It only takes an hour or so with s sawzall and a couple metal blades, don't be discouraged if you've by what people say it's dead simple. Diamond eye knocked it out if the park!

Installation wasn't as bad as I've heard. Noticeably more free flowing than the stock downpipe, I can now coast when letting off the accelerator.

It took me longer than expected but worth it. I did the riffraff 6637 filter and cat delete as well and can't be happier.
