Aftermarket exhaust, use stock gaskets??? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Got Sileighty? · 10-30-2004, 04:22 PM

hey guys, i just picked up a used catback (5zigen Border III 60mm). my question is, will the gaskets and bolts for a stock exhaust system fit??

also, someone suggested that i just buy a big piece of gasket material, and cut out the shape of the exhaust flange. is that even a good idea? and arent exhaust gakets metal?

btw, its for an s13 dohc, if it makes a difference. thanks.

***S14DB*** · 10-30-2004, 05:30 PM

It should have come with gaskets. but the best ones I have found are Project Silvia ones for the price. http://www.projectnissan.com/Product...&idproduct=637

Got Sileighty? · 11-01-2004, 01:31 AM

like i said, i bought it used, so no gaskets...cmon guys, i just need to know if the stock ones will fit or not. cuz if they fit, then i could just go to a nissan dealership and buy em there.

dct223 · 11-01-2004, 01:44 AM

U should be fine.. even if u dont have a gasket, ur car will still run fine since its exhuast

Wei240 · 11-01-2004, 01:50 AM

i bought an apex n1, used stock gaskets from nissan dealer, alot of aftermarket ones are paperish... stock nissan ones are only 5-10 bucks from the dealer, and speaking of which i have an extra set somewhere....

TheSnail · 11-01-2004, 01:56 AM

It will fit, but there is one problem. The center hole of your stock exhaust is 2" diameter, for a 3in exh, you would have a .5" wall all around, which would not do anything but create turbulence. Though 60mm is = to 2.36", it wont mater. If you plan on Na all the way, then it should be good enough, but if you are going turbo, you have failed

Wei240 · 11-01-2004, 02:09 AM

oh yeah,
didn't post up, but i have s13 dohc, just like he original poster,
so stock gasket is fine...

going turbo one day,
just don't know when...

andrave · 11-01-2004, 01:41 PM

go to autozone and they can match them up, thats what I did. I got 2.5 gaskets that fit mine, they were OEM on a jeep cherokee or some shit.

Got Sileighty? · 11-02-2004, 01:08 AM

wei, u still have those gaskets? i need 2 of them ...i guess im gonna go with the stock gaskets, problem is they cost $12 at the dealer!!!! then i went to like 2 autozones, a pepboys, and a kragen, and none of them seem to have any in stock...maybe ill try what andrave suggested. thanks!...but wei, if u have 2 of them, let me know.

Wei240 · 11-02-2004, 01:26 AM

yeah i do, two as in 2 pieces, it's sold as a set, as in 1 set = 2 pieces, (i'm pretty sure, it's actually in my glove compartment i think, i'll go look later),

i guess pm me for more info...

Are you saying to run without the gaskets? That's really not a good idea. Unless you like a car that sounds like a lawn mower. You will have exhaust leaks all over the place. Trust me not the way to go....REALLY ghetto.

Eternal_240Sx · 11-02-2004, 10:15 AM

Just go to a kragen, napa, or autozone and get a stock gasket for like 3 bucks. What i did for mine is i simply cut the gasket to make it 3 inch.

*crioten* · 11-02-2004, 11:15 AM

or you could make your own!!!

it sucks to make your own...turns out like a retard making paper snowflakes...

andrave · 11-02-2004, 12:19 PM

yeah buy smaller ones and use a dremel or something.

Wei240 · 11-02-2004, 01:57 PM

damn, just pay a little to get nissan ones.. it only costs a couple of tacos more...

The snail hit it. This is why you can't use the Nissan ones. Just go to a muffler shop, guarantee they have gaskets for you. I would rather get some that aren't modified and pay a little more then spend time trying to cut one bigger to fit and end up screwing it up.

NO i said, if they dont fit, he can run it without gaskets first, then get new ones. I wanted to SAY that since its exhaust, if he doesnt have a gasket for the time being (the stock ones dont fit, or are too worn), his car will still run alright IE., not sputtering no rough idle.

Not to be nit-picky but this post hardly explains what you said in your second post. I'm just going by what you said to begin with. Elaborating on it with your second post is what you should have done in the first place...

And if you WANTED to say it, then why didn't you just say it? Seems to be the best idea to always fully explain yourself since you have no idea WHO'S reading the posts and what their comprehensive level of understanding is. Just a suggestion. Not trying to start a flame war, just stating an observation.

okay My BAD, Ill make sure Ill double check and fully think out what i write on all my posts from now on...

Im sorry for my lack of time and effort on posts due to stressful weeks of school, i will step it up

Dream240 · 11-03-2004, 10:28 AM

it won't matter if he has stock header and stock cat, it's still around 2.5 all around, so stock gaskets still would work fine even if his exhaust is larger than stock...

All of the metal Nissan gaskets I got from the local stealership were 2-1/2"...but this was a few years back. Did they change to 2"?

Dream240 · 11-03-2004, 01:40 PM

Hell I don't know. I replaced my entire exhaust setup and my High flow cat has flare flanges so I don't need gaskets. Once I pulled all that stuff off I've never looked back. sorry I can't help more.

Wait...(light bulb just flickered)....The connection from the header to CAT isn't being touched right? Just the connection from the "FAKE" cat to the cat-back pipe. That would mean a stock gasket WOULD work. duh...I just realized that....Of course a stock gasket would work, since the fake cat opening is not changing, the larger diameter piping starts at the exhaust so everything before it doesn't matter. So yeah, use the stock ones!!!

OMG I can't believe I didn't realize this before....damn all that coffee i drink...got me SO WIRED!!!

Dream240 · 11-03-2004, 01:44 PM

wait...(bulb flickered again)....this would only apply to the one the mounts the new exhaust to the stock fake cat. The gasket for the two exhaust pipes mounting together will need to be cut out appropriately or get the right size from a muffler shop. sorry guys...

As far as the material, the Nissan ones are metal based gaskets, they looked like metal and everything but they're flexible like paper, good stuff. Most muffler shops should have this quality gasket in stock to fit what you need.

andrave · 11-03-2004, 01:56 PM

no one listens to me. go to a fucking parts store and have at it, they have ones that will work.

You mean there is a store down the street were I can get parts and I don't have to order off the net? I don't belive it....

axiomatik · 11-03-2004, 04:40 PM

Just go to a parts store, you can find gaskets in a range of sizes, 2", 2.5", 3", in lead, copper, paper. You don't need to go to the dealer or move it from some other spot. Find out what size you need, 2 or 3 bolt holes, and go to autozone or whatever.

Dream240 · 11-03-2004, 04:48 PM

Okay guys not to rain on your parade but, have you actually gone to a parts store lately? They a fuckin joke!! Really, EVERYTIME I go to an Autozone, Kragen, Pep Boys, Shucks, etc... they either have complete morons working there or they don't have the part (or tool)!!

For example, I went in recently to try to pick up a couple of exhaust hangers, you know universal part no biggie, they should have SOMETHING right? ahh no...first the guy behind the counter is totally lost when I said "exhaust hanger" or when I elaborated and said "you know the little rubber thingy that holds the exhaust to the car?" The guy just looked at me with total "STUPID" on his face.It was a Pep Boys BTW...and I've had similar experiences in Autozone mostly.

So now I just go there for oil, car wash soap, shammies(chamois), and maybe the occasional bolt or washer.

I mean unless you guys live in a different California then I do then I'm sure these stores will just waste your time....seriously try a muffler shop. At least you'll talk to someone that knows what an exhaust hanger is...hopefully.
