DIY: Upgrade your stock exhaust manifolds W/ Agency Power headers.

I agree.

If you install after market headers and after market VALVE LESS exhaust I think the exhaust will be very loud.

Also remember that without a valve the exhaust system is bound to have a drone.
Very annoying sound.

And that's why I opted for the Kline Innovation exhaust. It is valved so its quiet at idle but once the valve opens up it emits an amazing formula 1 race car sound.

Thanks for sharing great info.

I guess I wont even try to unplug the valves on mine as I dont want a drone headache.

Dan

 

Sounds good. Thanks.

Thanks Frank!

Sorry we were not able to meet up...... Hopefully next time you come visit Seattle.

And I only have Agency Power Headers on mine, plus stock exhaust.
My Kline Innovation Exhaust order has not arrived yet.
Its been 3 weeks...... I hope it arrives soon so I can install it ASAP and make the Ferrari engine even sound better.

All the best to you Frank.

Will do.

Thanks.

I want to provide an update on this:

1) The titanium wrap I used to wrap my AP headers is working very well. As I mentioned on my other post, stock exhaust manifolds - I get a reading of about 520F after I shut down my engine.

Now with AP headers wrapped with Titanium tape, after I shut down the engine and use my thermal laser reader - I get about 330F. That is almost 200 degrees less. Impressive.

Note that the titanium tape will emit smoke for the first two hours of driving or so burning off some of its protective coating. The smoke disappears and never comes back after the 2 hour break in period.

2) Another benefit I learned about upgrading to aftermarket headers is - I learned that the stock manifolds by original design actually retain heat, perhaps for optimum emissions reasons. Hence my engine bay with stock manifolds takes several hours to cool down and it really heats up my garage.

With AP headers wrapped with Titanium tape, after I shut down my engine, I pop the engine hood open to let the heat escape. I come back an hour or two later and the engine bay has cooled down considerably compared to stock configuration. So my garage does not get as hot any longer compared to when I had original manifolds.

Its been almost a month since I installed my AP headers and so far I am 100% happy. Zero issues, no check engine light and my stock exhaust sounds better. Cant wait to install my Kline Innovation exhaust.

Hope that info helps some of you.

Question please:

My friend has a Scud and is planning on replacing his exhaust manifolds soon.
He asked if the replacement procedures is the same.

Q: Does the Scud have the same exhaust manifolds as a regular F430?

Thanks in advance.

Image Unavailable, Please Login Update on using "Titanium Wrap" to contain the heat on my Agency Power Headers.

After one year I discovered the Titanium Wraps were deteriorating. Crap, that was a waste of time.
So my recommendation is if anyone is upgrading their exhaust manifolds to an aftermarket headers is to not bother with Titanium Wrap as my experience with the material is not very good. They do a great job containing the heat but they simply dont last very long.

See my post here:

Hope this helps some of you.

Your engine bay will get so hot it will start melting the wires in the engine bay compartment and start cooking some of the other engine bay parts due to extreme heat. You will smell burnt rubber.

I installed Capristo header blankets on my F430 now sold and it greatly reduced engine bay heat.
Capristo header blankets are expensive but they provide excellent heat containment of the aftermarket headers.

The OE exhaust manifolds have an outer shield with air space in between that reduces the heat the OE exhaust manifold emits.
Aftermarket headers is single layer / single tubes, that's why you need to insulate them.

Ceramic coating works but doesnt provide as good heat containment as high quality header blankets like Capristo.
Note that I have no affiliation to Capristo. Just sharing my experience so that people wont find out the hard way.

 

NOPE.

Been there done that.
My lessons learned is Do it right the first time and never have to worry about it again.
Install some really good header blankets like Capristo. Done.
Start enjoying the car again and not worry about cooking the engine bay parts or risk an engine bay fire.
