Worked perfect fit right had options for different cap off style on the intake where oil runs into. Took me all of 5min to do. 5 stars all day.
The quality and looks exceeded my expectation. My car has racing headers and has a resonator instead of a catalytic converter. This muffler was the perfect final touch and makes the car sound tuned not ricey.
Parts are nice and fit well. The AN 90* is a little flimsy but it works well for what its needed for.
They are working Great
First and second day after I installed them one of them was little lazy to open
But now they both open and close fine
And also the vacuum pump motor That runs a test every minute can be annoying sometimes
Other than that I love them
Nice kit, with out the premium price. A must for power strokes. Comes from over seas. Took about 10 days to receive, with good Communication along the way. Going to consider other offerings from SPELAB.
Parts are very well made and fit perfectly!
The material quality seems to be good. It definitely leaks exhaust, so the seal when the cutout is closed could be better. Since the 4" cutout uses a universal flange, it's very large and caused clearance issues for me. I had to modify it. A normal 3 bolt flange would be much better. I was unable to use the turn down due to ground clearance issues on my lowered car. It did bolt up just fine, but I had to take it off. That's no fault of the cutout. We'll see how well it holds up over time.
Very happy to see your comment, maybe the 4.0 size is a little bigger for your exhaust size, I can replace the 3.0 size for you for free. SPELAB wishes you a happy life
Once installed they sound killer! I have them on a 08 300c. It’s nice to be able to go to a silent exhaust when I am in the neighborhood then rip it open on the street. My only issue is I lose my 12v in the center console.
