Long tubes will require relocation of the cats so odds are you will not be able to use your stock cats. You will have to pick up a corresponding catted x-pipe. It has been a while but I think I picked up 30-40 rwhp in my 2005 with a tune.
Update: Found my old dyno sheets. 347 stock, 381 after long tubes and tune. Gain of 33 rwhp.

My header install has been a real nightmare and continues to haunt me. I got a name brand (from a forum vender) and they fit like crap. The vender replaced one header and it had the same issue. They've since turned their back on me and I'm left to my own accord. My issue is still not resolved.
It's too bad PFADT is no longer in business. They have the BEST design for the C6 cars.

LT and tune will net you the most bang for your buck but you must ask yourself: Self; Is it worth it?

I too had Kooks on my 2005 and they fit perfectly. I had zero regrets with them...well until it came time for smog. Damn you California!

The headers I got don't clear the trans cooler lines adequately and they rest right against the heat shield on the passenger side. It clanks horribly when the engine is running. Their off road x-pipe won't fit my car either. The tips won't line up and one side will not even seal correctly. I would post a full install blog about it here but the mods will just delete it. I will probably scrap them and put my Z stuff back on.
What's funny is the vender campaigns a C6 car and has been making the headers for years. They can't even make a product to fit a 2013 car though. Horrible.

Jack, A properly sized set of long tube headers will increase power and torque throughout the rpm range. We offer a 100% US made option that can be fine tuned to match whatever upgrades you have planned. I'll be more than happy to go over what you have in mind and help you select the perfect set up.
ARH started in 2005 and we started our manufacturing making Corvette systems. We've fine tuned our design early on to provide a system that fit well, installs easily and performs beyond what most expect.
As owner I can tell you with total confidence that we are the headers of choice for most of the top Corvette shops in the USA, Europe and the Middle East. I can also tell you, along with countless forum members, that we go to great lengths to make sure our customers are completely satisfied. Feel free to email me a contact number and I'll gladly call you and go over all the details including cost. My email is nick@americanracingheaders.com If it's easier, you can also find me at 631-608-1986.
Thanks in advance.

Dennis, Yes Vararam knocked off our system but they aren't capable of copying all the various options we offer to better suit different mods. We have different size headers and different mid sections that we most often mix and match to better deliver the power where the customer wants it most. Huge difference.

AR 1-3/4 cleared everything with plenty of room except for trans cooler lines on 2008 Z51 A6 base. A pry bar moved the lines enough to heat wrap them. I think the 1-3/4 provides more clearance and I'm glad I went with them,

I don't know Nick at ARH other than talking to him on the phone a couple of times, and his description is accurate. Told him what I was planning for my build, and they custom made my system - with phenomenal results. I had a Vette shop do the install, they said they were tight, but no issues.

And what were your phenomenal results exactly?
Thanks in advance.

I recently called Summit parts about headers for a 5.3 litre Chevy Silverado pickup and they informed me there would be no performance gains with the headers. No it was not a Corvette but still a Chevy V8. They impressed me with their honesty.
