Exhaust System

[mahoy]

Just wondering if anyone has any suggestions, I want to mod the exhaust in the car MKII Turbo Manual.

I think I just want to change from the CAT back, or should I change the CAT as well?

I contacted APS and they told me that the exhaust system is only offered in the Phase II system, and is a complete exhaust system from the turbo back.

I see no point in getting this as I am going to I want to get the edit a couple months after the exhuast is put in.

Furthermore they said, the Ford’s are very temperamental when it comes to modifying without some form of ECU device to tune for the added modifications. So they recommend that I have the vehicle tuned when fitting any extensive modifications to airflow/exhaust flow.

So does this mean that I have to get edited at the same time or is there a system where I don't need an edit staright away?

Sorry, if this sounds stupid, I am still learning.

No stupid questions mate as we are all still learning

The cat is the only real restriction in the stock system ( unless your chasing big numbers) so that's the part you're better off spending your $$ on. And yes you will need to get an edit to account for increase in flow.

If it's just a better note you're after just do the centre muffler mod:spoton:

Mahoy....does that mean that APS wont sell you an exhaust system unless you buy the Phase 2 kit?

In my opinion a cat back system is a waste of money as the cat is the major restriction in the system. If you are to get a turbo back system you would need to get a custom tuned edit to suit it. If you change the exhaust and find the car runs fine without a retune then the new system isn't any better than the one it replaced.

If your in Sydney give Tuffy's a ring or ask DBOSS or BCL. If in Melbourne give the guys at Fastfit in Frankston a ring. Both shops do good work.

I was told from APS that the exhaust system at this point in time is only offered in the Phase II system. From what geea and APS has said there would be no point, in buying the exhaust system buy itself.

So would I just be better off removing the center muffler? If I remove it should I put hotdogs in? Would I need a custom tune if I removed the center muffler? Would the generic CAPA tune work?

With the edit, it is my understanding now that CAPA generic tunes are so good now its not worth getting a custom tune, is that correct?

I hope to get about 240rwkw. Is that possible with stock manual T56 2nd Typhoon CAI/BMC Filter, Center Muffler removed, without putting the stock internals at too much risk?

I wouldn't change the exhaust at all for 240rwkw's.

Just remove the centre muffler if its just better sound yer after....no adverse effects.

I am running the 8psi generic tune and was happy with it. Albeit, I am booked into Intune for a custom tune on Tuesday.

No risk at all at 240rwkw. Intune tell me that I can expect around 260rwkw at safe levels. I am a little sceptical but hey. If the lines are nice and even and the AFR's are good, I'll take what I can get.

Cheers

If was was to remove the center muffler, should I go for straight pipes of hot dogs in them, is it worth getting pipes with mandrel bends in them?

Does anyone know what rwkw the Generic Capa tunes are roughly getting on average,? I know that each car is different.

I think I saw a thread that said that capa says the generic 10psi will give you 240atw..

the exhaust will be louder and a little dronier (?) with the straight pipes v the hotdogs..

straight pipes is cheaper and you wont need a tune if you do this mod..
