Default to keep it stock or not to ( catback )

I want to order the Pacesetter and TSP catted Y, but I was thinking of leaving the stock catback on, would it hurt that much? I figured I could always replace the muffler later on.

I've seen some people do this and just put a cutout before the muffler, never heard it in person though.

Thats what I was thinking of doing, would be cheaper to get an electric one so i can still have that stock look and sound.

why, with a catback you will get a little bit better gas mileage. unless you go with a restrictive system.

It's just so god damn hard to choose the right catback for me, thats why. I don't like anything too loud like a loudmouth. I was thinking Magnaflows but people said there too quiet with headers and cats and blablablabla, if there were only a line of samples i could use(ls1sounds doesnt have any).

my buddy did that on his car and had the slp catback and it sounded good with his headers and ory pipe. Sounded really good when he put a cam in too. If you cant make up your mind i say just leave it until your sure of what you want. i know i changed my exhaust setup at least 3 times.

My brother has my old magnaflow catback on his '98 Z28 with headers, ORY. It's not quiet at all, sounds ******* amazing actually.

I have that setup with flowtech long tubes and ory, and lt1 catback(vacuum cleaner)

With cutout(in I pipe) open it sounds like any other boring ls1 with an open cutout... they all sound the same, but with it closed it is barley noticable that its louder then stock and has a nice tone and whirl like sound to it.

I still have the stock catback with headers ORY, and a cutout, with a cam. It surprises so many people it sounds almost stock with it shut.

Keep the stock catback and just put a cutout before the axle.

I wish I would have done that. Just buy a cut-out.

2otl? Loudmouth+ORY= Sounds like ****, no ifs, an, or buts about it. It has the most ungodly rasp. between 2000 thru 4000 rpms sounds like glasspacks. If you meant SL{ Dual/dual go for it. It flows pretty good and will be louder than stock because the lack of cats.
