Thank you guys for your interest in our products in previous threads. We take a lot of time during the prototype phase to make sure fitment/quality is top-notch. For those that have followed us over the years in other forums you are well aware we take customer feedback seriously, and have adjusted our products accordingly. We currently offer longtube headers for Corvettes, Camaros, CTS-V, GTO, TBSS, Truck/Suv's, and a variety of swap applications. If you guys have any questions just let us know.
If anyone has any questions about these LT's, ask me. There isn't too much information on the forum about them, but I took the leap and installed them. Fitment was great, none of the steering shaft/oil pan issues with these.

Yes, unfortunately we do not offer cats with any of our exhaust systems for cars or trucks. All of our exhaust systems are a slip fit design, and on this application will require making two cuts. Which, in all honesty is not that big of a deal. All the newer Camaros and CTS-V's have a one piece exhaust system from the cats all the way to the tips, and don't even have a connection point. Those require cutting as well in order to tap into the factory mufflers. The reason we cut using reducers is so our exhaust will stay a full 3" to the end of our system. This will allow guys that would like to run a 3" cat-back an easy 3" access point to our X-Pipe.
With all slip fit connections, couldn't we just slip cats in line?
$385 for the complete system through Amazon -- with free shipping, no less. I'm going to bet the gaskets are not quite GM spec.
Yes, some customers have added in cats to our system. Not sure if there is enough room to make it slip-fit, however adding cats is defiantly doable.
Our standard gaskets included are just a graphite paper gasket, like the old SBC gaskets. If you upgrade to the multi-layer steel gaskets yes they are either GM, or a manufacture for GM's gaskets depending on which batch we have at the moment. Either way the quality from what we have seen is exactly the same.

Any idea how much of a PIA it will be to bolt these up to my Corsa axle back?

Just the axle back? Still have your stock H pipe?
The issue I foresee is similar to mine, where the X pipe ends, and the axle-back begins, is a difference in length. You're going to have to either buy some new pipe and weld/clamp it in or use part of your stock H-pipe setup. See the product picture earlier in this thread, where the picture stops is the problem spot.
This system does not use the hanger located at 0:39 in that video. So you're going to want the spring style hangers located back near the trans. So it's likely you're going to have to cut up your H pipe. If you have the Corsa X-pipe, you'll be in the same situation.

Yes, I have the stock system on right now, going back to a Corsa. I may just put the headers on and rig up the X pipe and take it to my local muffler shop and let them mate the X pipe and the axle back. I guess I wont know until I'm installing.

Idc if anyone says about this "budget" setup or how anything may be "rigged", this sounds out ******* standing.
Hi Sean,
Just had your system installed on my 09, with npp, and a tune. Wow my vette sounds completely different and pulls like it's new. The 24 inch 02 extensions seemed short so I did not use them, went with 31 inch no issues. Can I send these back for a refund? Highly recommend these headers and x pipe, save your money for the tune instead of 1000.00 dollar headers.
Thanks again Sean,
Ron
Doh just realized this is the C5 section, sorry.....but I'm sure they will make the C5 sound great also .

Looks like my prayers for an affordable, but well fitting, set of longtubes may have been answered. I too already have corsa X-Pipe and xtreme axle back, so I will have to figure out the best way to cut and merge them together. I would probably have the headers ceramic coated and a pair of resonators welded in too while I am at it.
Curious what the ceramic will achieve. In olden days I'd have worried about corrosion, but less so with stainless. Are you thinking of keeping under hood temps down, or perhaps thinking keeping the heat in the exhaust helps maintain exhaust velocity?

All the above, but mainly temperature control. Less cooking of engine bay components such as the spark plug cables etc and less heat radiating into the cabin.
