430 Removing Cats from OEM Headers and Repairing Them

Well I guess that is the question we all are wondering.... I have a 2009 and I’m trying to keep my car as stock/original as possible. It did come with a Fabspeed cross pipe track exhaust but has stock 2nd gen headers. The Fabspeed removes a ton of weight off the back of the car and should remove a lot of stress on the headers. I do have the original ferrari exhaust and putting that back on whenever I sell the car is a heck of a lot easier than putting back the stock headers.

The big question is how many people had the 2nd gen headers go bad on an 08 or 09 with the improved 2nd gen brackets and a lighter muffler setup like the sport exhaust. I know there are cases of 2nd gen cracking but are they on earlier cars where the rest of the setup wasn’t upgraded(ie brackets and muffler)

Cheers,
Corey

no.
if header is already cracked, i'd remove header, gut cat material , weld/fix the crack , install them back without the brackets.
if header not cracked, just remove the brackets, keep driving until it cracks

 

No my headers are perfectly fine. Car has 3500 miles

 

remove the brackets now
nothing else to worry about

 

ok.
so what scenario calls for switching to the factory sport exhaust?

 

factory sport exhaust is cat-back.
regular oem cat back exhaust is presumably just quieter and heavier.
except for regular oem cat back exhaust's white powder issue, there ain't much to worry about.

so you only switch them when you need something louder and lighter

no headers or cats involved in this particular area

 

On my 06 i have cap headers with blankets, cap hiflow cats, and cap brackets. I Hesitate doing the tubj sport because everything else is capristo.

Yes that's definitely the cheapest option. Scud and challenge headers have the exact same heat shields as a stock 430.

 

I would think replacing the catback would be strictly personal preference regarding sound and weight.

I know that I wouldn't hesitate for a second in using a different brand catback, if I preferred the sound.

Very helpful thread. Can anyone show me on a picture which are the brackets that can be removed and not replaced?
Thanks!

 

Diffuser has to come off and they are right there, easy to see. They mount to the rear of the gearbox.

im going to dyno this setup above (oem muffler) and will post results.

 

This? sorry im a complete rookie. So removing these prevents the headers to crack?
Can I remove only the defuser or do i need to remove the whole bumper
THank you!!

I had my cat delete on a 2007 f430 spider here in FL. I have a constant CEL, but damn..... the sound is bananas !

Thank you!!
What is the rationale, do they limit the movement of the headers and therefore provoque the cracks?
Thanks again!!!

 

yep. u got it

 

Yes. Here’s a video on 360 exhausts, comparing Capristo to Tubi.

Essentially yes, that exhaust mounts on rubber hangers so is free to move. Any header "can" crack though.

 

so theyre arent cracked?
