CT5V BW exhaust

[theprototype]

Very very interesting. If they’re the first to come out with an exhaust I’ll be in line waiting to pick one up!

Kooks has one in the works. No details on valves yet.

I spoke to them on the phone a few weeks ago and they confirmed they will have valves. Based on what they said they should be available for order in the next month or two!

Can't wait for the Kooks system. I'll buy as soon as it is released.

Same, just want to try and retain the stock tips

Wow that sounds perfect! Is kooks good quality? Never heard of em

I used em for my s550. Amazing quality and sound.

Yup, Kooks is good quality, have run at least 5 different systems over the last 10+ years!

Guess I know what to tell my wife what I want for Christmas.

I had headers and cat back on my 2006 Jeep GC SRT-8. The catback was SS Works and the headers were Kooks. Both great and sound was phenomenal!!

This is excellent. I've been a Corsa fan for my other GM vehicles and they've always come through when something wasn't right.

That's awesome. Here's to hoping they give us something good. I used Corsa back on my Mustang GT and loved it.

I hope they design the pipes in a way that will work with the Kooks Headers, though.

So i have the catless kooks longtubes with the factory exhaust, with the valve closed it has a nice growl, with the valves open it is basically a straight pipe. No drone in either mode.

For people with headers is the catback simply for weight reduction? Or is this just a mod for people looking for only a sound increase?

Even with the valves open, stock muffler reduces the sound. My custom bypass mufflers are louder, but not by much.

@A Blackwing - i know its subjective, but how much louder is your car with the headers + stock muffler compared to stock everything ?

Kooks without cats is the only thing left to make mine louder, so I'll probably end up doing it. I hate to pay so much for the tune since all I want is to change some settings that will get throttle response back to where it should have always been.

It is insanely loud with catless headers and valves open on stock exhaust, plus the headers make it louder AND add power remove heat.

So with my truly open pipes it really will be insanely loud.

I'm considering it since I still have the valves and can calm things down when necessary. I can hardly wait..........

You need to tune with headers though and to remove CEL, correct?

No. I had my headers on for 4000 miles before tune and never threw a CEL

I do wish the 5BW exhaust was a bit more nasty like the Escalade V. It's almost 'refined' even though it does have a good tone and decent volume OUTSIDE of the vehicle.

I agree with your assessment. The reason they were able to make the Escalade V louder was because there are different standards for the exhaust from cars than there is for the exhaust from "trucks" like the Escalade.
