a cutout on a stock manifold car can decrease your power. you can ask 01pewter2001z28 what it did to his car. They are tuned for back pressure and when you drastically change that w/o a tune it can do more harm than good. no muffler with cats or w/o sounds like ****. if your not turning that bitch 9k or 10k rpm at the track theres no sense in it. Get a Y and a decent catback and youll have a hell of a good sounding car w/o being called white trash.
I think the cats and crushed up stock Y-straw will offer some backpressure. Mine ran 13.4s with the muffler hacked and a RVT'd lid. I doubt it would have done much better, but who's to say what the next fellows car would do.
Headers, for example. My car didn't gain a DAMN THING with a full exhaust. She's one of the few that can't improve without a tune...

Sure, why not? I've seen plenty people waste money on catbacks that didn't sound all that peachy. Honestly, these cars with nothing but a hacked muffler sound great.
If you're looking into a catback anyway, cut it off before you head to the shop. If you like it, cool. If not, you were planning on a new muffler anyway. It's a win win situation.![Nod](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_nod.gif)

Ha ha this thread reminds me of an old sport compact car article where they said they could make a nissan sentra faster then a new porsche without spending any money. Needless to say the sentra was gutted to just a platform drivetrain and one seat. So hey want your camaro to be faster then a zo6 for free??? get the hacksaw ready.

Do you know what a dump is? Like an exhaust turndown.

dont listen to the one above me. bigblackss is talking about where to cut it to remove the muffler and 180ls1 your talking about where to cut it for a cut out. bigblackss yes cut it so the pipe will be facing the ground so there's no chance of the exhaust just canstantly beating on anything.( a friend put a glasspack on a 4cyl 5spd ranger and thought it would be a good idea to put the turndown up facing out of his drive tire so when he did burnouts it would blow the smoke away....Next 2-3days his e brake cable melted lol) i had a 1994 mark viii and i cut the mufflers off right as the pipes were facing down, sounded great looked better without the tips as will yours. and when you put a cutout out behind the rear or remove the muffler you really dont get as much interior noise. my 02 camaro with a spintech(got a whole catback with stainless tips for free) was loud as hell inside and that was still full exhaust.

I say just remove all exhaust right up to the exhaust manifolds and put some of that auto parts flex pipe right out the side of your door with coat hangers,(joking). I personally have a cut out and hate how it sounds. I only open it at the track. I like my set up with the magnaflow,ory and mac mids much better.

whatever dude but you are completely wrong. Try reading again i know it is hard but please do it before you say i am wrong and not to listen to me. That happens to be the same location as a cutout but i nevet said to use one since the poster does not want one.

[QUOTE=180ls1;10009375] i now get what you mean but basically it sounds like more work than you have to for nothing. cut it off where its already aiming down dont waste your time turning it and save your money for a real exhaust. i only did a cutout because it was cheap and sounds great when i got the spare cash im gonna worry about a cat back.you can just make one cut and its done. plus with the cut after the rear you dont get as much interior noise. and dont get cocky i misunderstood it my bad but now that i get it it's still more work thats not needed.
