Shorty Headers

I would like LT headers but that would make it not pass smog in CA, but shorty headers are fine. So can you guys tell me what are the best shorties in your opinion and what type of rwhp I would get from them? Thanks.

Solo Performance and JBA both make shorty headers. Mine are JBA.

My shorties and high-flow cats did very well on the track for me.

I think you'll be pleasantly surprised. If you can get the high flow cats also, they are the biggest gain. The shorties gain, but the high flows gain more, and together, sweet. The high flows don't involve moving the sensors or changing the tune, so maybe you can get away with it in CA.

I've had some success at the track running Doug Thorley shorties and cutouts just aft of the OEM cats. They were easy to install and easy on the bank account.

Yes I did. Much easier than LT's. Just got to make sure you seal things up well so no leaks. Check my Build Journal for more info and what happened when I took them to the track.

None of them are good if you run them through the stock cats.

I also went with the Doug Thorley, been on for 1.5 years and look brand new still. The DT's are coated and look awesome, just make sure you wipe down what ever you get before starting the first time. That way you won't get any finger prints or discoloration burnt into the pipes.

If you want performance in cali, bolt on a supercharger. Other wise you are wasting your time. Shorties dont do crap and stock cats are horrible. Just do it right, and then register in another state.

I would also be very cautious with the high flow cats, I haven't seen any that last very long, especially with any type of FI setup OR pass a sniffer test after you get some miles on them...

You guys don't pull any puches, do you?

Y'all can "dis" my shorties and cutouts, but I outran my son in his C5 Corvette with LG Motorsports long tubes:



How's that for "not doing crap"?

By the way, the OAT was in the high 90s that night.

Good driving does more than good power. Im glad you like your car and you should, but i will never pay money for shorties.

I don't live in California anymore but......

Be aware you can't even change the Cats if you want to stay legal and pass the inspection.

You could put your stock Cats back on for your first test in 5 years though,and change them out every other year after that.

For the hassle of going through all that you might as well get long tubes.
No real gains with shorties and takes just as long to swap out.

LOL. Don't sweat the lemmings. I gained about 4.5mph in my traps with just my shorties and high flow cats. Without a tune.
