Just as I was about to order one, but then I heard about valve problems.
Two guys already had trouble with broken valves. You will find the videos on youtube...

Interesting. Dynomax had similar issues when they released that dual mode muffler a few years ago. 2 people with them after such a short time in the wild is definitely concerning. Corsa does make a really good product, I am sure they will remedy it but I am not sure I will purchase one until they do

My valves haven't gone bad yet, the exhaust maybe has 1000 miles on it so far. we'll see what happens after a few track days.

The sound is exactly what I was looking for in a cat back. When I do ARH LT Headers back to the axle i'll be even happier.

When the valves are closed it is very similar to how the facts suitcase is closed. IMO with out the potential faulty valve issue this exhaust is perfect, in my opinion.

So 3k+ for an exhaust that has faulty valves. Seems like a steal to me. ����

I’m so in on that!

Is that a warranty breaker crack, or no, ya think?

I mean, all legality regarding causality & all.

It is a completely different controller from the ECU, so I don't think it would void the warranty. Probably gonna depend if the dealer can see it trip a flash counter if they check for it.

Ugh I have this issue
Kind of glad I stumbled on this thread
I have less then 1000 miles on the npp corsa exhaust

That's the plan! I have an AWE Touring catback exhaust without resonators. I plan to add 1 7/8 catted headers. Considering how loud it already is, I plan to pick up the AWE resonators to add back in during the install. Anyone selling AWE resonators?

Touring- Opens for start, closed idle and cruise in all gears below 4k rpm

Sport- Open start, open idle, open cruise in gears 1-3, then closes for the rest of the gears part throttle below 3200rpm.

Track- Open start, open idle, open cruise in gears 1-5, closes for rest of the gears below 3k rpm.

Snow/Ice- closed all conditions.

You will have to read entire when you hook up HPtuners and then it will show the FSCM controller. There is a thread on Exhaust valve tuning in the tuning section.

Thanks for the synopsis.

I started out in Sport when I got it, then switched to Touring. Thought it sounded different. Good to know. LOL
