I have the 2.5" collectors on mine, which I believe is the standard setup if you go the full y-pipe and cat route.

I have found Stainlessworks pretty willing to customize its products, so if you aren't worried about cats and y-pipe issues, it might give you more options.

I would call Stainlessworks and tell them what you are up to and see what they say.

 

Hi Guys

MoreGrip-glad you were happy with the headers! Let me know if you need anything.

We can offer the headers with a 3" collector and no y pipe, or a 2 1/2" collector with a catted or off road y pipe. Is there any interest in a 3" y pipe?

Thanks

Judging from the quality headers I would get the y-pipe but I have dual exhaust if pacesetter doesnt get off their *** with the 4wd headers then Ill probably end up getting some with the 2.5" collectors.

 

We need a y pipe for the 6.0l Equiped trucks with the dual cat pipes,

here's a pic of the stock 6.0l assembly;Don'tr mind the coating


The only bolt in kit with cat pipes for the Silverado SS, VHO, Denali is Dynatechs

 

How much did they set you back?

 

Al,

Do you think a 408 ci motor would be to big for the 2.5" collector. If it is then i would definitely like to run the 3" collector w/Y-pipe if you guys are gonna offer it. I have a Silverado SS with the true dual till the muffler. BTW this would be with NO cats.

 

Al,
For the silverado SS crew, that run true duals to the mufflers, I am sure there are a bunch of people who would love to see you make a 3" set of Y-pipes.

At this point that is what is holding me up, is how to either modify my existing pipes, or buy a kit. I would rather see a 3" kit than have to modify my own. Bolt on kits are nice.

Just my $.02

 

How about a 99 4x4? I don't have AIR, and no longer have EGR since the 02 PCM swap.

Bring the truck to us and we will prototype the lead pipes on your truck. I will give you the lead pipes for free, and you buy the headers.

Or, if anyone has a Silverado SS in Cleveland, let me know. I know there is a market for this, I just need a truck for a few weeks.
