Remove stock catback? I was debating whether or not I should remove my stock catback on my 98 Z/28... As you can see in the pictures the pipe and muffler connection is somewhat severed and the whole catback itself is rusted and whatnot, not to mention the muffler is close to falling of because of the drivers side clamp that's holding it is not very secure. I have a cutout waiting to be place on the i-pipe but now I'd reconsidering putting it on at all because of the condition of the stock catback. Should I go ahead and put on the cutout and get the pipe welded securely back to the muffler or should I just remove the catback completely and risk getting pulled over? Anyone run open stock Y pipe (w/ stock manifolds)? Too loud? I'm just worried about getting pulled over, I can't get anymore tickets. Any input would help.
Thanks

Yea I'm leaning toward's removing it, I was just worried about how loud an open Y pipe would be? Because I'm not sure when exactly I can pickup a new catback. I was looking at a TSP rumbler catback, but as I said I have no idea how long I'd be running an open Y for. I'm *guessing it isn't too bad because the stock manifolds I've heard are quite restricting and it still has the cats.

If not,
Thanks anyway!
Yea it has the complete OEM exhaust, so stock manifolds, cats and catback. Alright I'm probably going to remove it then. Once I get LT's and drop the cats I'll pick up a catback so I don't wake my whole town up hah. Would you be able to get a video/sound clip up on here? I'd appreciate it.

Yea that's what I was thinkin. Pacesetters and an ory with an open Y will be loud as hell! I think that might be too loud hah, but definitely a badass sound to hear before you put a catback on.

I'm running a 3" Y-pipe with stock manifolds... My exhaust is dumped about a a foot and a half after the y-pipe sounds AMAZING! Haha but luckily I haven't gotten pulled over yet, I try not to accelerate hard when a cop is next to me

Borla is pretty amazing so I've heard, and I know what you mean about flowmaster hah. People only buy them because of the sound or they know nothing.
get a sound clip up of your car with that setup if you can
If you just want to dump it right after the Y-pipe, but don't want it to loud then get a Magnaflow (#18129 bullet about $45) muffler or a Moroso Spiral flow(#94051 about $55) and a aluminized turn-down (about $20). That will keep it from being to loud at a low rpm level.

I plan to get longtubes with an ORY and dump it right after the y pipe... and maybe have a straight through muffler right after the y pipe near the center of the car... different than what alot of people do but it should sound great!

Here are two videos, sorry for the crappy quality though I recorded it with my phone.
