Thanks guys .... the car dose feel little stronger now and for $650 shipped with ceramic coating could not pass it up. And they also hooked up to my stock catalytic converters....also I have no more drone with Borla stingers ! Had them installed at my friends shop because some welding was required. Not sure if I need tuning because I'm running the stock cats.

I would get the cats and then the tune. Why leave anything on the table. Make sure you have all the principals installed so you only have to get a tune once. Tunes can be expensive!! It would be no different if you got it tuned before you installed an intake/cold air system.

finally got a dyno tune at Excelsior Motorsports in Escondido with high flow cats previous owner dyno 354 to the wheels with intake but I'm not sure what kind of dyno it was maybe a dynojet for mustang dyno
base line numbers were 320 to the wheels with mainline dyno. After efi live tune 337 then 345 then 353 then final 365 whp . 45 hp gain from a dyno tuning is amazing . Kushan told me that his dyno would show lower dyno numbers. Just would like you're guys input thanks.

So if I reading your post right the previous owner made 354rwhp then you bought it and added headers and got +11rwhp after headers and a tune?
Did you install the headers yourself?

Different type of dyno, so you can't compare the previous owners numbers. The OP posted that his before numbers were 320rwhp on this dyno....and the final number was 365rwhp

If the car feels smooth and strong now though, that's all that matters.

no the headers were installed at my friends shop because it required some cutting and welding. Next is a set of ported heads and cam for sure. Thanks for all your input and advice guys!

What welding/cutting is required for the install? I have been a Mustang guy for over 10 years and the aftermarket with them is typically a bolt-on job. I had to pay to have my LTs installed on my Cobra because of clearance issues with the kmember. The engine has to be jacked up and supported to get them on, plus a lift is best, which I don't have. I am shopping for a Z06 and want to learn what the best mods are for real performance gains.

cutting and welding because was not a full kit like kooks ,american racing, the pipes had to be cut right in front of the cat and then welded and also the engine mounts have to be removed and the steering shaft. my friend was not too happy installing them lol. this is my first Corvette and I was told that the best mods are long tube headers intake and high flow cats. Also get it dyno tuned not a email tune ...without spending a lot of cash. Good luck finding your z06
