430 F430 Header Install Question

Which manifolds did you get?

 

They only fit one way.

 

Be sure to fit new studs and nuts, known to break studs so not worth re using them, cheap enough anyway.

 

I ended up not using the Kline gaskets they sent with the headers and ordered a new OEM set. Unnecessary? Probably, but I figured the OEM gaskets were cheap enough.

You’ll love the headers. I just installed their 100Cell Cats to complete the full Kline system (headers, cats, exhaust).

 

How are you going to get the old studs out ?

 

15/16 of the studs came out with the nut when I did mine. Took that one stud out with one of these:

Link does not work for me. You were lucky as some people have snapped them

 

I soaked them for a few days with Aerokroil to help loosen them up. I’d be lying if I said I wasn’t sweating the entire time worried about one snapping off.

Trying the link again for the stud extractor:

Can you post a picture of the Capristo test pipes? Are they part mesh or solid?

 

I make my own out of a bit of hex bar and an allen screw, you can then reverse the procedure to refit the new ones,
Very useful given how little room to work

 

It’s definitely louder, but that was what I was looking for. Been happy with the sound.

 

Its helps if you measure the distance between centres of the fitted cats, before you take them off- it will give you a reference to work to when mounting the new ones

 

Thanks for everyone's' posts. Armed with 12mm and 13mm stubby wrenches, candle wax, kroil and now the stud extractor thing. Have challenge headers on order for 55 weeks w trending to Feb shipment.

Plan to swap to titanium bolts on header ends. New studs, OEM gaskets and copper lock nuts (13mm) in hand.

 

Did you do the heatshields or was that an option from kline?

 

The main downside of the heat shields is you don't get to appreciate the workmanship of Kline's welds since they are pre-installed, but then again you get to appreciate their work on the heat shield which is also beautiful. And yes you do need heat shields with any header on the 430 so in the end you have to cover up Kline's welds at some point.

 

See how long you can stand the noise, i took my Capristo non valve silencer off after 2 years and went back to oem, silence is golden .

 

Oh I plan to keep the OEM valved exhaust as it is plenty loud already. Just going with challenge headers.
