Gutting Precats or New Manifold

Anonymous · March 18, 2004, 20:47

Just a quick one, is the extra power from a performance 4-2-1 manifold worth paying the extra for or is there really little difference between that and simply gutting the precats for free. Note: I don't want to include 4-1 designs such as Team Moon since I don't want to be shifting all the gains to the top end. What do ya reckon? s:twisted: :twisted: s:twisted:

I don't think Team Moon makes manifolds at all...you must mean PPE...?

Also, I don't think anyone else knows if it's worth it to you s;)

Soz, I meant PPE but I'm actually asking for the opinions of others and thus assumed that any views expressed would be whether or not it would be worth buying a replacement manifold or gutting the pre cats in the eyes of whoever replied, otherwise I could just ask myself and save myself the time taken to type this out.

Cheers TEM,

Soz for the aggressive response but I'd just been surfing SC..... s8)

Sounds good though, I was just looking at the Top Secret yesterday seems a bit pricey though so a similar item at a lower price would be cool. Just hope the Pre cats don't give up in the mean time as has happened with Mike's 2m Mines an 03 too but it seems that ain't any sort of guarantee against engine failure unfortunately.

Why not PPE header? what you assert is a metropolitan legend. See my dyno torque with PPE/high flow cat:

Rusty I know it seems bad but my car was most probably an exception. I haven't heard of any other 03's touch wood! Plus mine cracked..it didn't fragment like others (though I have no doubt it would have given time). I was gutted when I found out about it, and seriously considered selling it. However these things happen, and you have to forget them. I get to drive mine tomorrow when I get back home, and i can't wait haven't seen it for 2 weeks. Plus if you fit a header your warranty will almost certainly be void won't it? If you want one for performance and your willing to forego the warranty then great get one..but if your getting one to pre-empt the pre cats failing IMO its not worth ruining your warrany for.

Admittedly as soon as my waranty expires the pre cats will be going to the great junkyard in the sky!

I wouldn't worry about the precats, chances of them going within next two months is next to 0. Of course it can happen, but...

that's very reasonable. so does this get rid of both the pre-cats and the maion cat? and will this solve the bad cat problem?

TEM, at about £300 I'd definitley be interested in the manifold especially if it's similar to the Top Secret. Tell us "whoever" it is that's going to be selling them to let us know when it's available! I'd like to put my name down for one. s:D

It's just a manifold, so it only gets rid of the precats (both of them).

It connects to the stock cat pipe, so it's up to you if you want to keep that or replace it s8)

Do you know that that manifold is to throw away if you mount a turbo? s:(

I bet it's easy to sell the manifold, if one decides to go turbo s8)

I deceided to de cat the 1zz manifold last night i'm using with the 2zz flanges welded to it for my install.

It is such an easy job, took about 15 minutes with a screwdriver and hammer. What are the pre cats made out of? China?

There is no pre cat residue left in the manifold as it surrounded by some sort of cotton. The pre cat chunks come out whole.

Yeah, precats are usually ceramic. High performance ones tend to be metal. I'm waiting to see what TEM's manifold is like - I'm thinking that I'll probably go down the performance manifold route rather than gut the cats - resonance tuning and all that.

Just for the record...I have nothing to do with it...it's someone elses project s8)
