Will An S13 Exhaust Fit An A31

[Lum]

I've been offered a Mongoose exhaust from a 180SX (well UK 200SX) S13 with the CA engine, and would like to fit it to my A31 Ceffy. It consists of everything from the end of the turbo elbow.

I realise that this isn't going to bolt straight on, but I'm hoping that at the very least the downpipe and the silencer will go straight on. Any idea how much work is going to be involved in getting the centre section to fit. Does it take the same route under the car (I believe the A31 and S13 chassis' are closely related) in which case I'd just have to chop it in half and weld in a bit of pipe of a suitable length.

I'd rather use the Mongoose than go to Powerflow and get a custom one made up as Powerflow generally target the chav (Bogan in Oz?) market, creating gigantic fart cannons that aren't always tuned particularly well, wheras the Mongoose will be reasonably discrete and is known to work well (on CAs at least)

Also if you think this is a stupid idea and I should do something else, please tell me!

nothing will fit, mate. tried it.

Downpipe flange has to be rewelded. Catalitic converter flange is also different angle.

Silencer is wrong. Nohting will fit without mods. A31 have tire well there. And silencer hangers are different to s or r chassis.

Thanks for that.

So my next question is, what exhaust can I get?

Given the rarity of Ceffy's in the UK, I guess it's going to be a custom jobbie? A shame as I like the twin exhaust look of the Mongoose (basically a bigger bore version of the standard S13 twin peashooters)

Aftermarket cefiro exhausts are very simple, mine only has 1 bend from the cat back and it's only a very small angle (like 10-15 degrees).

It still sits very high off the ground even with a mid muffler, alot better than most examples you see on S13/R32.

If you can't find one at an import parts shop, I'd suggest getting an exhaust shop to make one to fit, rather than trying to make an S13/R32 one fit.

Not to mention the cefiro/laurel has a longer body than the S13/R32.

Laurel parts are interchangeable with cefiros in case you didn't know.

Here is a catback I have in my garage, as you can see it only has 1 bend in it.

The exhaust I have on my car at the moment has a proper oval muffler in position of that resonator thing, and instead of the cannon it has twin pipes.

The other exhaust (currently on car), you can see there is plenty of room for the muffler to sit nice and high. I've pointed to the cat converter and front pipe, just for reference.

I have no intention of keeping a cat on this car as there's no legal requirement for me to do so. Cats reduce fuel efficiency anyway and we're constantly told how bad CO2 is I was looking at a turbo back system

[daisu]

For a turbo back, use R32 dump pipe (RB20), you'll need a custom front pipe unless you can source a cefiro/laurel aftermarket from jap import shops.

As for the cat, just replace it with a piece of pipe, or if you are getting your catback system made at an exhaust shop, just have them make it longer to meet the front pipe.

Having a bit of language difficulty here. I'm guessing by dump pipe you're refering to the bit immediately after the turbo elbow? I'd call it the downpipe.

No idea what a front pipe is, sorry.

Edit: A bit of googling and looking at pictures of bits of exhaust on Australian parts websites, and I'm now guessing dump pipe = turbo elbow and front pipe = downpipe?

Yeah, it goes turbo, dump, front, cat. Though you can buy 1 piece dump/front pipes.

[Hella Flush]

on both my cefiros i used R32 dump pipes and front pipes... fit no problems at all...

[daisu]

I keep forgetting I had a backyard job dump pipe, and that's probably what made the R32 front pipe not fit.

[Lum]

Any idea if KTS exhausts are any good?

Looking at the dump/front pipe from here then get the rest custom build locally. Does this seem like a good plan or should I get the entire thing built custom?

hey mate , i build custom exhausts for a living ( sister lives in wales too lol but im stuck in aus ) . if you can source the front pipe easily then do it . off the shelf will always be cheaper than custom made . custom stuff is needed for when your car is modified or rare . source the front pipe and then get the rest custom made . either that or try to source a complete exhaust from japan to suit . seeing as you dont need to run a cat in the u.k you may have some luck getting one off a race car

Thanks for that. Problem with getting stuff from Japan is the cost of postage, plus the pound isn't doing very well right now plug all the decent Japanese makes are really expensive anyway. Do the pics of those KTS parts look like they're decently made or do you think I should avoid them and find something else?
