View Full Version : need pictures of stock exhaust from headers back

01-07-2011, 02:25 AM
need to know if this exhaust would replace the cat:



if so, is there a way to just keep the B-pipe with this exhaust and use the cat back and headers?

according to this, if I use the I guess cat back, then it should work, right?

I have the stock header. After that isn't stock. You still want pics of that? Yours a GT or GTS?

from the pic it looks like a complete replacement but i dont see a cat in there

Going by the pics that doesn't come with a cat, and it's not a cat back, it's a cat delete pipe. If you look at your Toyota diagram, #6 is your primary exhaust pipe; it has a primary and secondary cat in the pipe. A cat back pipe for that car is just the 2 rear mufflers [# 11].

You're probably going to have a hard time finding a complete pipe replacement with the cats in it, most aftermarket companies only care about cheap and easy to sell.

If you're having problems with the cat [codes, clogged] you can try an aftermarket weld in one. It may or may not work.
The OE replacement is very expensive, but it will have a lifetime guarantee and is double walled stainless steel.

I know it doesn't have a cat in the aftermarket one. but can I use pipe 6 with the exhaust and headers and leave out the long pipe in the middle from the aftermarket? she's got a 2000 GTS and is trying to keep it legal until she gets it inspected.

You should be able to.
Each individual piece should bolt in on it's own.
I don't know how much difference the manifold is going to be though, is it worth the cash?

my general experince is that you cant just substitute factory parts in the middle of a system like that as they dont follow the factory lines exactly when they make them aftermarket. Sometimes they can be made to fit, but I wouldnt expect it to bolt right up without a little tweaking.

woah now, I'm gonna have to take the cross member off to install the headers?

That picture made me appreciate the 7th Gen a lot more.

Yes, unless you have magic hands that can work contorted behind the engine against a firewall. Removing the crosssmember is pretty easy, and allows you so much space to work. When I pull mine, I typically clean it and inspect my motor.

The header on a GT-S is a PITA to remove (so I've been told)

I've never done one on a GTS [don't see a lot of them at work], but the 1ZZ isn't too bad, you just need a long extension and a flex socket.
Is the 2ZZ very different?

2ZZ is just as easy as the 1ZZ. we have a thread on NC.org about removing the 2ZZ header. what we actually do is remove the valve cover, front and rear motor mount bolts and rock the engine and take it out the top.
