headers and valved exhaust system

Would like some of your opinions on Agency Power headers and valved exhaust system compared to iPE similar setup. They are both about the same cost.


I have seen a few members recommend or are using the iPE system but haven't seen anyone mention Agency Power system.


Would also like your opinions on the row boxes and filters. One of the shops I talked to said that the stock system flows pretty good.


Lastly is it worth the money to install the oil separator?




Thanks for any responses and sorry if this is repetitive but couldn't find anything comparing the two on a search

I have the IPE headers and mid pipes and I am very happy with the quality of the exhaust.
They are busy being fitted to the car at the moment. I will get it back later this week, and then I can give you an idea of the sound and power increase.
I haven't bought the rear valvetronic section yet. May get that at a later stage.

Agency power and iPe are the same thing. Search ROW boxes. There is pretty much nothing reasonably priced ($2500 rentech intake) that matches ROW airboxes. As far as the air oil separator, some will say it's needed. Others will (me included) will say otherwise. At 70k I had very little oil or carbon in my intake or on the intake valves.

Just get Friedrich Motorsport headers. At least half the price of the AP and iPE. All 3 are identical. I have them installed on my car and I made 463whp with just headers and tune (no ROW boxes at the time).

Row boxes and filters are one of the cheapest mods you can do. They are not necessary in order to enjoy the car, but every little bit counts.

Are you sure they are identical. I contacted Friedrich Motorsports and they replied that their headers will not fit on a RHD car.
Then I contacted IPE and they said that their system will fit on a RHD.

Sorry I was talking about the LHD, didn't realize you were talking about RHD

Yes, I'm pretty sure they're identical. I compare the tubes lengths and diameter. Design is exactly the same as well as the lengths.

2013 C63 P31 Coupe (my 3rd C63!)
Check these out......

This is an Australian brand that I believe is new to the American market. I own a performance subaru shop and recently started carrying this brand and am planning on trying their products on my car, but unfortunately I have a coupe and they only make a sedan catback. I am thinking that their headers and universal mufflers are the way to go. Check it out!

Headers:

C63 Sedan Catback (no valves):

Their product that interests me the most is universal mufflers with active valves built in:

ipe / Friedrich / AP all the same made in Asia. I have the AP headers and they haven't failed me. Made 477 WHP and 440 TQ with them.

PS: Row Boxes don't do much if anything at all. Save yourself the money and just remove your charcoal filter / swap your stock air filters to an AFE / K&N.
