I like the quiet stock sound, my other cars scream i like this one quiet. My down tubes are leaking. SO, what are my options, i think the muffler is ok. Probably keep the stock header. What can i do for downpipe options that wont make is sound super loud. The air intake added enough for me lol.

Identify the source of the leak precisely:
- let the engine get cold (wait till morning)
- open the engine compartment
- turn on the engine
- use the next 2 minutes search for the hot air with your fingers and palm (feel for hot air popping out of the pipe somewhere)

You need to find the leak to know what to replace.

If it is the flex-joints then you are buying a new down pipe (this part has an expensive catalytic converter)

It it is a gasket then you you need a new gasket for $5.

If it is something else then you better know what it is. Many other random holes can be fixed at the shop for a minor charge.

Yes it will raise the volume a little. It will not be as bad as a cat bypass.

The alternative is to by a OEM style cat (new or used) or pay almost as much as new to have new flex-joints welded in. I managed to have one of the two flex joints replaced and only paid $100.

Yeah, I got both flex joints replaced at a muffler shop for $100-150 I think. I have a custom exhaust though, so I would have bought a down pipe and still pay the muffler shop to cut and weld it in; it was a no-brainer for me.
