Hi guys, after a little advice! My exhaust is blowing so its time for an upgrade, not wanting to spend much money on the new exhaust as im looking at doing a turbo build later on and this exhaust will be useless. With that in mind i was ofcourse drawn to the Ebay specials, having searched around for one i *think* fits my engine/model ( JDM 2.2 Si F22B) i came up with these from the same company:
Manifold & Downpipe

Question is, is this the right manifold for my Engine (F22B)?

De-cat

Again is this going to be the right length De-Cat for my JDM when used with the rest of the system?

And finaly Cat Back System

Again im assuming all Cat-Back's fit all models? I could be wrong (wouldnt be anything new Razz

) so its better to ask you Lude Guru's!

Overall question is, will this all work together (you would assume so being from the same company) and will it fit my Car (JDM 2.2 Si F22B)? And ofcourse will it gain me power, loose me power or break even with stock?

Im not after power gains from the system realy, that would be a bonus. The exhaust needs to be replaced for MOT due to it blowing and this whole thing costs about as much as some Cat-Backs so its a winner there. As i have said, the system will be getting replaced with a bigger 3" (i think) system when i finaly get around to turbo'ing the lude so dont want to spend much more then a few hundred quid! Smile

Anyway im rambling, opinions/advice please! Very Happy

Hi I thought I was the only F22b in the village lol,

what type of F22b do you have? cos im sure there is a SOHC version and I know there is a DOHC version, cos I own one and its a b!tch to get bits for.

As for the exhaust manifold on the F22b manifolds from the H23 apparently fit properly as for H22A manifolds the mounting bolts are slightly further apart (as in height wise) than the F22b's ones, I too have been looking for a turbo kit for mine

Hope this helps with some of your hunting, also the first manifold looks like a H22 fitment but without measuring the mounting holes I could not tell you for sure.

Hi mate, can't tell you whether it will fit an F22 but in terms of gains, I dare say that it would be an improvement over the stock system, particularly as your exhaust is blowing!

Actually, I'm at a similar stage in that I am currently upgrading my system. I bought a s/s mani from TuningParts Bay:

and am now looking at investing in a de-cat of some sort to work alongside the mani and a Blueflame catback system.

If you are going to go the turbo route at a later date why even bother getting the decat and manifold at all? Seems like a waste of time and money in my opinion.

I've got a 3 inch exhaust system that was from my 2.2 vtec laying around but I'm not sure if it'll fit the 2.2 non vtec.

I fitted one of these last week to my H22a as my flexi pipe was leaking so went down the stainless road, it was a job I wish I hadn't started as the manifold bolts were solid and heat shield mounts would not budge but got there in the end! Wink

I did worry about loosing the heat shields to start with but havn't noticed any probs so far.
Welding on the pipes is very good and for £100 it won't rust ever

I've actually seen these rust. I'm not sure what stainless they use but I'm thinking it must be grade 409.

Yeah I think it's the lower grade stainless that they use. I've had quite a few manifolds I've made with no rust at all.

@EFFX: i do believe its the DOHC but i may be mistaken, i know diddly about engines! lol, the site states: "Direct bolt on installation with F22 2.0l, 2.2l Non VTEC engines." So i was hoping it was a direct fit, if anyone knows either way? that would be a great help! Smile

@DJBlobby: How did you find the mani? good quality (for the price Wink

)? Any noticable gains?

@dohc-vtec: Like i say, the whole system is the same price as some cat-backs so thought why not? Il no doubt take months/years to finaly get my turbo build done as i find it hard to get time to work on it, i dont get every weekend off from the army and when i do get them i dont always get time to work on the car.

@norfolk boy: I took my heat shield off today with no drama but i think my mani will be a real bitch to get off! theres 2 bolts/nuts that are rusted to hell! and one bolt i cant get access to very well Sad

pic's included to show what i mean:

*edit* Forgot to say, thanks for the replies & keep them coming! very helpfull!! Very Happy

The only thing I can recommend is continually spray wd40 on each night for a couple of nights. Should help to free it.

Then use a pretty long wrench to get it undone.

I found that I actually removed all of my studs when I did it, I just soaked them in WD40 for a bit, so I could get the nuts off. Then used the double nut technique to put the studs back.

One thing I would recomend is use a hex socket and not a bog standard socket as they will damage the nut profile and then it becomes a nightmare. I fired the engine up to get a bit of heat into them which will help release.
The heat shield bolts were easy (those ones anyway) its the ones hidden away that were buggers to free. You will know which ones when you come to release the manifold section Shocked

Good advice, never heard of a Hex socket before, il have to have a look for one! Heating up the bolts is also a good idea, apart from the resuling burnt hands lol. By the hidden ones do you mean the bolts holding mani and dp together? cause they do look like a REAL bitch to get too lol

Long extension on a socket wrench and it's easy. I've stripped a few threads getting them off, but if your replacing it anyway it's not a problem

Haven't fittted the mani yet mate but have heard from a number of people that do have them that they are good value for money in terms of the gains they provide, so looking forward to getting it done Razz
