Default 2003 z06 LT header question

I have a 2003 z06 with a intake only. Wondering if there is any low end torque loss with ARH LT headers or similar brands. I love the way the car pulls even in stock form but wouldn't mind a bit more hp / torque. But i dont want to lose low end torque in the process of adding LT headers. As we all know its not a cheap purchase so would love to hear feedback. If its worth the dough as my plans are to keep the stock cam it would just be tune/ ported TB, ARH LT, HF cats and stock titanium exhaust.

LT's won't disappoint. Better midrange, upper, drivability, sound... I've installed headers on pretty much every V8 I've owned, always happy with the results.
My 04Z is pretty much identical; K&N intake, Texas Speed headers and tune, Magnaflow cats and X, Ti's.
Don't know if a ported TB is worth it this close to stock... is it?

I added LT's this year and I can say there are NO downsides to them. No loss of tq, engine breathes way better, runs and sounds fantastic. Only regret is I wish I had added these years ago

I'll agree with what's been said. I did Kooks headers and dyno tune back in the spring. Nothing but good things to say about this combo.

LT headers are a no-brainer. Any of the major brands will be a quality product with gains across the entire range. I went with Kooks and they have been flawless.

I didn't notice any loss of low end torque with my 1 3/4" XS Power headers. Car rips down low and pulls hard all the way through the powerband.

LT's and stock Z06 cat back has been one of my favorite sounding exhausts for the C5 cars.




We have a number of different options on headers depending on what your goals are for the car, and of course we have a Forum member discount too!

Love my longtubes, was disappointed by how quiet the car was with TI at idle. At Woot it isn't too bad.
