FabSpeed Cats for GT500

[Jmeo]

Found these today, and I don’t think I have heard of anyone running them. Pretty good option for someone wanting more power, more sound and no CEL. Especially anyone who will be installing the Whipple SC.

Very interesting and I see you can upgrade to a bypass option setup as well. Already looking forward to your review Jamie.

So you can buy these, or you can buy a set of 2” primary Kooks headers with green cats for $200 more….I’m honestly not seeing the value of these

I can see your point. Having installed LT headers at least 6 times now, the one benefit with these, will be the ease of install alone. Other than that, LT headers will be a bigger bang for the buck.

Some people, self included, have zero want to do headers again, lol.

Also no tune.

Dont forget the $2-3K to install longtubes.

I did these style in 30min at my track garage on my 350.

I wish i knew about these. I had to have my race pipes custom made.

Gotta say if you spent 2-3k for installation you got ripped off. My last set of LTH were $600 installed at my local speed shop.

Honestly if your just bolting on pieces without a tune you’re leaving so much power on the table. And warranty schmoranty…once you swap out the cats (illegal by the way lol) you’ve committed to understanding you may have zero claimable warranty issues with the exhaust or motor.

While I agree 3k is extremely high, $600 us unreasonably low. I can tell you every local shop in my neck of the woods charges right around $2,000. Having done them many times, 10 hours is a reasonable time estimate, no shop is going to do 10 hours of crappy work for $600.00

It's not about power this time, it's about better cat protection. High HP supercharged engines destroy cats over time. I would want to do this to have a better flowing, less likely to fail cat. Free HP is just a bonus. The fact these can be installed super easy, and stock cats replaced just as easy, warranty is not a concern if there is a failure.

You make valuable points, I am just here to argue that there are other reasons to do something like this. I will not tune my car because I am not interested in that worm hole (this time), but a bolt on pair of better performing cats is in the same category as an axle back bolt on exhaust to me.

On a forced induction engine with a warranty still in place I would never remove a factory cat in order to exchange it for an aftermarket unit. Marketing bullshit aside, metallic substrate cats fail miserably under duress and that's how you pop a boosted engine quickly. The latest factory ceramics, while somewhat restrictive, are as robust as we will ever see on an internal combustion engine.

In this day and age, either go all the way will full lengths/no cats/tune and say bye bye to your warranty, or be a good boy until the warranty is over. Or gamble with a 25k engine, whatevs.

If your shop charges you $200/hr that is a ripoff. Local shops around me are about 95-110/hr hence why my price was so low. It took them just under 7 hours to install the headers on my GT and a Barton shifter.

Oh I wouldn't pay to have them done anyway, I do them myself. I just know a lot of people that did (and from more then one place). Yes, they are charging that much money around me. Absolutely crazy for sure.
