ok so i have a 96 ls and i did straight piping with an apexi royal and it sounded great but then i decided to put on some headers (high tech Reps the 2 piece one) n after the headers were on it sounded horrible.... so im pretty sure its not the muffler because it was fine before the headers were on... can anyone help me

 

What does "sounds horrible" mean? Is it raspy? Do you have a resonator? Do you have a catalytic converter?

 

no i dont have resonator and it sounds normal ultil i accelerate n the noise is like a loud hi pitch rattle almost

 

Do you have the correct donut? I assume the heat shields have all been removed.

 

it had correct donut... the headers are 2 1/2 and pipe is 2 1/4 but i got the adapter for it with the donut the flange kit that goes from 2 1/2 into 2 1/4..... i think it has something to do with the headers because thats when it all started

 

whats a good resonator to get?

Can you make this rattle when revving without moving the car? Is the rear header support installed?

 

I'm not an exhaust expert but a resonator would probably help, I'm assuming it's a custom bent exhaust from the cat back?

 

i just noticed i have a bolt missing at the header support could that be the reason for the sound? and also i have a leak where the two header parts connect.

 

i think u just answered your own question buddy... fix the leak and your raspy noise will probably go away.... LEAKS = ugly sounding exhaust
