J's Racing 70RR Installation Issues

[DC2-PWR]

Out of curiosity, how much did you pay for such exhaust

wanted to know this as well

^ as above ... and Matlew, I was talking about modifying the 4-2 downpipe on the stock exhaust to make it fit somehow onto the 70rr bpipe. I really need find out some measurements of the 70rr 2-1 downpipe and see if anything is possible to modify and put a different cat on the 2-1 dc5 downpipe.

I'm asking for other suggestions how how to install the exhaust. Not what exhaust I should have bought. And also, there is no such thing as a 60RR for a DC5R.

If there was such thing as a 60RR I would have went for that. I have done some extent of research, but there isn't much out there.

I think he might of meant 60rs

Also from this website there seems to be a titanium one you can purchase. Here's the link http://au.tougedistribution.com/item...-CFX-T5-70RRP/

Could have but yeah ... I do know about the 60RS definitely. But from what I have gathered from my mechanics and few friends and also Pizzo has even said himself that a 70mm application would be ideal for a complete bolt on setup.

60RS is what i mean't.
Thanks everyone for the correction.
Do you have future plans for the car (Eg. Engine work)?
Long term goals?
If yes, then 70mm is fine, but if it's just going to be a daily street car, i would of opted for the 60RS.
60RS bolts up to the AUDM headers as M@lew correct me....
So why didn't you get something that was a direct bolt-on hassle free for what i believe is a daily street car yes?

I'm not meaning to be a c*nt but makes no sense to me into why you'd get the 70RR...
Anyway, will love to hear the reviews plus also see how you went about correcting the issues your having now.

not relevant to topic,

any more posting not related to how to fit a 70RR with cat converter will be deleted...

Yeah well I didn't want the 60RS for obvious reasons because of my long term goals. And was prepared to go though the hassles. I have taken plans of the following.

Header
RBC Manifold + 70mm port match
70mm TB
Injen CAI (Too much heat soak with my current carbon SRI)
Fuel rail and maybe injectors + fuel regulator if needed ?
K-Pro

Might look into head work but at my budget, doing the bolt ons are the best option at this stage. Will also look into final drives and carbon syncros later on too.

Stephen,

Can you post up a picture of the exhaust that you have ordered. I just want to see I'm thinking of the right one.

Thanks

[tinkerbell]

is what i picture....

[45SET]

I'm thinking the same thing... if thats the case, you won't be able to run any part of the AUDM header.

There was all this talk of using the AUDM headers... and I just realised why.

Big week.

I've just gotta stay out of the tech section...

[tinkerbell]

yeah, so AUDM header wont be used, but OP still needs to work out how to add a cat converter to whatever 4-2 section header setup he decides to fit...

[Stephen_AUS]

Here is the product, but its just going to be stainless.



Yeah I do realise that it will not run on the stock AUDM headers as again it is a 4-1 construction.

Ok so here we go again ...

Requirements : must have a cat for street use.
In near future : will run aftermarket cat.
What I would want to know : which option is worth doing? what would you do if you were in the same situation as me?

Option 1 - Partially cut the b-pipe and weld a 3 bolt flange to fit as a catback exhaust and in the near future run a aftermarket header with cat. (Easiest option)

Option 2 - Buy a Spoon/J's Racing 4-2 section header and modify the 2-1 downpipe on the 70rr to fit a cat on. (Will ruin the 4-2 section though will get a 70mm flow headerback, unsure if that makes a big difference or not)

Option 3 - Buy a DC5R JDM header and modify the 2-1 downpipe by slicing off the stock cat, weld a smaller aftermarket cat then customise it so it can be sleeved straight onto the 70rr b-pipe without cutting. (Quite a fair bit of work involved but it wont ruin the 70rr and will allow me to buy an Spoon/J's Racing 4-2 header in future, though unsure of allowable length)

I also had another thought as well but it's really not intended to do because I want to run aftermarket headers, but I will share the suggestion. So I keep the 4-1 AUDM header, make a 1-1 downpipe section with cat and allow it to sleeve onto 70rr b-pipe.

Again all I am after is your suggestions on what could possibly be the best option in your opinion.

[gunpoons]

i'd go option 2 and cut a high flow cat into the 2-1 section, between the sensor bungs
and yo, that thing looks LOUD!
