430 Replacement Headers

Topic probably tackled a few times if you search. YouTube videos too.

 

I have the Capristo manifolds with insulation blankets, very good but not cheap. Consider the manifolds from the 430 scud, a lot cheaper than the oem 430 coupe ones

 

scud manifolds arent immune from cracking (mine did). the tubi and capristio headers are the top of the line for the 430. if you want good value go for the challenge car headers form eurospares:

RichardCH i believe had a set of capristo headers crack on him (he has had a number of setups but i think im accurate) but capristo headers cracking is rare. the one reason i didnt go tubi was because i dont like the tubi muffler on the 430.
tubi makes great stuff.

 

Nothing wrong with that advice!!!

 

The capristo manifolds on mine made no diff to the sound that i could hear.

 

I would be surprised if a carpisto cracked, they are made from T 309 ( used in gas turbines) and a work of pure art. I think they carry a lifetime warranty to the original buyer.

 

Richard texted me. His capristos did not crack.it was a broken bolt and his headers are for sale if anyone wants them.

 

Thats a good price- the dealers say to fit new studs and nuts when changing manifolds. Very cheap parts as well

 

While ur doing the headers i wld consider 200 cel cats. That will enhance the sound bigtime.

 

They collect the gas from the cylinder heads and discharge it into the cat converters. Look on eurospares uk web site for the exhaust system diagram

 

I would be surprised if any aftermarket header didn't increase the volume. My challenge headers certainly did. Maybe only 15% though. Removal of any cat will bump the volume. Cats are pretty effective mufflers.

 

My Agency Power headers gave the car a low growl sound that i never liked. I imagine they all do because of no cats built into them

 

How do you find the AP headers to the power band? Does it shift around from stock? I know stock pulls pretty consistently to redline.

 

I sold the car over a year ago so dont remember. I sure do remember that growl sound tho

 

I hope that’s the case with mine too. Im getting capristo manifold installed in next few weeks. Currently I have MK2 headers and stock exhaust and it is more than loud enough for me already.

 

Dont the stock headers have precats in the them? Aftermarket doesnt so id be shocked if there is no change in volume.

 

I’ll let u know after they go in. I’ve been driving it a lot in preparation to see if I can feel/hear any differences after.

 

Just confirmed oem headers have precats. No way the sound will stay the same.

 

My neighbors are not going to be happy

 

But you will be!

 

I must be going deaf then
