Dinan exhaust question?

Jus wondering what set up goes well with the dinan exhaust free flow exhaust. I am looking into ss headers, would stock cat or ss xpipe make that much of a different in power or is the free flow and headers suffiecent enough? just curious what the different would be?

The Dinan exhaust is desgned for the stock cats and resonators. Someone about two years ago added a xpipe to their dinan exhaust, and it sounded terrible (he was trying to sell the exhaust on the board after about 2 weeks of having) until he replaced the xpipe back to stock. I don't know about how the ss headers would sound/perform w/ the Dinan exhaust, but I don't see you getting a lot of additional power with the xpipe or cats once you've done the headers.

Do a full super sprint setup or do the ss headers, cats xpipe and choose a nice exhaust lik kellners, eisenman oe you could go with a supersprint.

The M5 I am getting already has a free flow exhaust, so just wondering if the ss headers may be the only thing else I can add for a decent gain in HP. I have to admitt, I like the sound of the dinan exhaust. I don't feel the need to replace it, so just doing what I can with what I already have.

The super sprint headers will definitely lighten the front weight while producing some serious hp and torque. Our M5's share the same exact headers as a 540i and also as a E38 7 series.

That was What I am thinking. So I will keep the Dinan exhaust and ss headers and that should be enough fo me and still great results. Any idea on the HP and Torque gains with a dinan exhaust and ss headers?

while the headers will definately gain you power, they're not any lighter than the stock exhaust manifolds by any great measure.

I agree with you, but kinda sucks handing over twice as much money for what. What would be the dyno different between the two different headers with the same dinan exhaust? Is it worth the extra 4-5k for it.

-SS and Dinan headers make about the same power at peak (Dinan might make a tiny bit more), but Dinan's are a proper 4-2-1 and will make more power through the entire rpm band. Dinan's also won't crack or break, and are CARB legal. Only you can say what's it's worth to you.
