    • Great fit
I was a little skeptical about the fitment. Cause several people said they had a hard time getting at the bolt up. But I had no issues at all with getting it to bolt right up in place. Got at least a 1000 miles on it. Since installation Ck light still off performing correctly.

Haven't even got it installed all the way yet! I HATE leaving a bad review but it is so much different than the original. I believe the volume of the front 2 converts is prolly the same but the lack of quality and it was damaged or creased BEFPRE they sent it because the packing slip was over the damaged area! I've already got my truck tore down so I hope it's not got a pin hole. My dad was a Class A Pipe welder most of his life so I know what welds are supposed to look like. And this ain't it. BB's everywhere. Curls left inside tubing from drilling holes for weld-o-lets. Bends aren't smooth. Was overheat then tried to fix. I hope it even bolts up! Oh and the slip flange isn't a third of the thickness of the factory one I took off.. I understand making as many, as fast as you can, but still a lil better quality in my opinion! If it bolts and lasts, I'll come and adjust this, but for now this is, what it is! ... show more

    • The product finally showed up several days late!!!
The product didnt show up at my door until 5 days after said delivery! I didn’t even think I was going to get it, So I put a cancel on it. It showed up after the I put the cancel in. It did fit but had to modify the connection bracket at the pipe to the muffler.

Seems to be working well. Has been installed for 2 months now. Way cheaper than oem or magnaflow.

    • The precious metal load in these is sufficient for the job.
These converters were sufficient for me to pass my emissions test. Don’t waste your money on the cheap Chinese ones you’re wasting your time. They’re only good at idle.
