So just right now i was trying to install my corksport exhaust N/A. I noticed that i do not have a spot where the catback cuts off from the y-pipe. It goes from teh header to the cat and all the way to the mufflers and there is no other points that bolt off.

There is no where that the y-pipe unbolts from the main converter. the only point where it comes off is where the front converter meets the header

Anyone got any solutions?

 

are you meaning you have no places to have the hangers hold up the exhaust?

 

No there is no where for me to unbolt the main cat. The only places on the exhaust that i can unbolt is where the cat meets the front cat and the mufflers.

On both sides of the main cat there is only piping.

 

so from the front of the cat to the end of the mufflers is one piece? sounds not-stock. take some pics to verify this.

 

o0oo your talking about on your stock exhaust.. alright i thought you ment on the CS exhaust.. yea.. dont sound stock to me..

 

Yes this is exactly what it is. except for I can unbolt my mufflers. Well now I know what it is. What can I do to replace this.

This gives me a good opprtunity to get ride of my front and main cat. what would be a good way that i could get rid of my cats and replace my header. I was looking the corksport stuff but they only replace the main cat. what could i get to replace the front cat?

 

you only need a main cat replacement. If you want to remove the other ones either gut them or get an aftermarket header.

 

get a complete racing beat exhaust!

 

RB FTW!

or if you just want a cat get the bonez high flow which will bolt right from the stock manifold (including the pre cats) or headers to the cat back

 

The problem is i can not remove my main cat. The only 2 things on my exhaust that i can unbolt is where teh cat meets the header and where the mufflers are.

I would go with a full racing beat true dual but i already spent money on this corksport so i wanna be able to use it i was thinking about the racing beat Catalytic Converter Replacement Pipe with Presilencer

Does anyone have this setup? how is it?

 

i dont have that set up..however. if your cat back and your main cat are one piece just take the whole thing off and run the bonez high flow (or the presilencer) off the headers to your CS cat back. dont know if thats an answer you were lookin for.

 

Wait, do you have a header, or are you talking about the stock exhaust manifold? We need some pics to figure out exactly what you have. If its a header and you have the stock main cat welded to the stock y-pipe, then you can replace all of that with a OEM replacement car liek the bonez cat. If you are saying that you have all of the stock cats and they are all welded together, then you will have to get something designed to replace all fo the cats, like the RB header/presilencer combo.

 

this sounds very not stock, maybe someone has already taken care of your exhaust

pics please

 

Ok, I think I understand what's going on, please correct me if I'm wrong.

He bought a corksport header and cat back, they are designed to work with the stock cat in between them. The exhaust that's on the car is stock, but it's been welded up everywhere except at the mufflers and manifold.

So it seems like you need a new cat, the old one probably wasn't doing too well anyway, clogged, broken, whatever, it's probably either not doing much for emissions, or it's restricting flow more than it should.

 

Well i only bought the corksport catback.

I would post pics if I had a digital camera on me. My stupid cousin broke mines and still has not replaced it yet. Cannon SD700

But what Black 91 N/A said is exactly what is up with my exhaust. I can only remove it from the manifold and the mufflers. All of my stock cats are welded together.

I looked through all the paperwork for the car and some small smog shop had replaced the cat. on the paper says direct fit converter which i assume is some kind of self fabrication. hence the welds

So im planning to go with RB cat replacement pipe with pre-silencer??? Any suggestions or comments?

 

Or get the bonez high flow cat like somebody previously said- its a direct replacement for the cat you have now and works with the stock manifold or an aftermarket header. Try rx7.com they offer them. Ive got one with the same corksport catback and a racingbeat header. It all flows very nicely.

 

Unless he needs to pass emmisions, there is no point in getting the cat since it costs more than the RB downpipe/presilencer. As for the RB stuff, thats going to be your best bet. If your engine is ported or you are planning on porting it in the near future, then the header will be better, but its not needed for a stock port motor.
If you're really cheap then you can get the Bonez cat replacement pipe, but its not very well made. The flanges are too thin and will warp over time (took less than 2 years on mine) creating a permanent exhaust leak that can only be fixed by replacing it.

 

I looked at the bonez high flow cat. I live in california and I don't think that I would be able to pass smog with that and a catback unless anyone has any other information that I would???

Im most likely gonna go with the RacingBeat downpipe pre-silencer.

 

Oh crap, didn't notice that you are in California. Well, the downpipe/presilencer obviously wont pass smog OR visual. The bonez should pass smog, but the visual is questionable. From what I've heard some places will pass visual as long as there is a cat, while others require it to be stock or replaced with a CARB certified cat. Its actually possible that it is CARB certified, though. I would call up RP (rx7.com) and ask them if it is or not.

 

There is a point to running a cat, emissions and smell.

I've got an RB downpipe/presilencer combo. It's very well made and sounds good. You can also get a Bonez cat that fits in the same space as the presilencer. rx7.com sells them.

 

Hes in cali, though, so the header wont pass visual. I think the best bet is to get the Bonez cat that replaces the whole thing.

 

Living in the east bay area I've never heard anyone being visually inspected by cops. I mean my friend ran catless for a year on his civic. So i don't think It should be a problem for me.

I looked through teh FAQ on the cali section for Smog. Some people have been able to pass with the bonez super flo system. The visual thing isn't a problem the place I smog at the guy usually just looks in teh engine bay and tahts about it.

So this week Im gonna think about should I go with the Bonez or The Racing Beat.
