Diamond eye exhaust

[maxx1963]

Just put a down pipe back Diamond eye "quiet" system on my duramax. I can really feel a difference, I will be towing again in 2 weeks, I cant wait to see the difference.

That's good that you like it so far. It's difficult to find any downside of supporting a made in u.s.a company

you notice much more turbo whine?

[maxx1963]

yes a lot more turbo noise! I did put on the "quiet" system, it has a resonator on the front pipe where the cat normally is so in the cab sounds almost like the stock system. i defiantly notice a power difference.

I put the diamond eye and the Cheetah turbo at the same time. I have LOTS of whine, but I blamed that on the cheetah..
