Im currently running on my99 ls1 tune and cai, but i bought some txas speed headers and idont want it to be to loud, would it be ok to leave the stock catback with the long tube headers? Or add some magnaflow or corsa with some high flow cats?

I have LG Pro's with Corsa catback car is okay sound wise but when I hit it she gets loud not in the car but outside. Just start with stock then if you want it better add to it.

The headers will make things louder but if the stock catbacks are just too tame for you once the LT headers are installed, I'd recommend the Corsa catback - I run the pace cars on mine and love the sound.

Sounds good... I shall get it installed with the factory exhaust should give a nice sounds... Btw im adding a comp cam too to it...

Add the Corsa. The factory exhaust restricts the air flow to much. If your doing all the engine work let the car breath better with a better exhaust system

Well i was thinking of adding the headers w stock exhaust and adding some cut outs? So when ill be at the track or street ill just open them so it could get much air flow? And so is for the cam... I dont really move the car i just want a cammed out corvette lol smh... Since im not going with a converter i wont be waiting for a good time lol.. Just like the chop chop
Of the cam..

But next step after installing those little things ill get a corsa cat back..

or you could save yourself a buttload of cash and get the stock z06 ti catback. it flows just as well as any aftermarket, weighs next to nothing, fits great, sounds really good and can be had for around 400 all day long. depending on what cam you get the stock converter will make it a pain in the butt to drive. the TSP headers will require some tuning to get rid of the rear 02 sensors as well as turning off the AIR so you do not get any CELs. Also you will have to cut up your tunnel plate to install the headers so the front 02s will clear.

Yea a friend of mine has that zo6 exhaust he wants 400buxs... And im going with a custom grind cam special for the car and its madd to work in the car with a converter... Thanks for those details man really appriciated...

What cam do you all recommend me? To see if i made a good choice or not?

MAINIAK

I mean the cam i ordered is special for a NO converter setup but its ovious that if i put a converter it will work badass
