Muffler delete with quad tip kit?

I have the NPP exhaust and love my quad tips but am looking to get it a little louder, is there a muffler delete kit with quad tips?

If you do this, let me know how much you want for your NPP mufflers.

Have you considered long tube headers or even cat delete pipes? The NPP sounds sweet with long tubes and no cats.

It's all in who you know down at your local inspection shop. You can get high flow cats with the long tubes and it will still make it louder then the factory manifolds and converters and it will still be legal

Stock headers? You mean the manifold right?

But I had the setup you're talking about. It was actually pretty loud with muffler delete, I was VERY pleased with it, definitely worth it.

I have LT headers now, still have muffler delete and it's very loud. Just too raspy though, sounds very untamed.

I've got the Pfadt LTs and HF cats with NPP... M2W switch is set to open pretty much all the time and it sounds amazing. Just loud enough to enjoy it without it sounding like shit. It's the first time I've not wanted to change mufflers in all the performance vehicles I've owned over the years.

That is just badass wicked!! It's times when I heard exhaust sounds like this that I get some serious V8 envy!
