430 Whom makes the best F430 exhaust headers sound wise ?

Anyone has any feedback about IPE headers ?

Nobody has the Kline in stock and they take over 3 months to make.

 

No experience yet, but they are on my list to go onto the car in the near future. seem like the best bang for your buck to me for equal length headers

 

I always liked the sound of IPE headers/exhaust, but found some old thread where an owner dyno’d several different header setups and the IPE lost power. I’m not looking for a drastic increase, but it kind of sucks to lose power after spending all that cash and time.

No heat shielding was also a deal breaker for me.

 

I highly doubt a free flowing header with no built in cat will lose power... I kept searching but did not find that thread... Do you have more info by any chance.
I agree about it though; if I spend a day changing the headers (mainly for my peace of mind as oem can crack) might as well get some gains too; especially now that I am tuned , hehe

 

With the iPE, you lose a lot of power and even more torque, especially in the mid-range, and they don't make up for it until the end. I had them on the Dyno.

 

OK.... then how about the Kline, are they granted to gain power ??

 

I can’t remember where I read it on here, but some were saying the 4-1 design loses some power in the midrange. I believe the best way to fix that is if you have the car tuned by Trev or Mase, etc.

I had a CEL when I put the headers on. So went with the tune from Trev. My car is an 08.

 

...ok... so there is a 4-2-1 design... Capristo I think? Does that guarantee power gains ... This becomes a can of worms I see. What headers did you go with ?

I just put Capristos on mine 2 weeks ago.

 

I went with Kline. I didn’t notice a loss in power, but I also do t have any dyno results to prove it.

 

From a performance perspective alone I would place them somewhere in the middle ground. My order of manifolds based on design for performance is below - higher is better:

1. Stock (small primaries, terrible merge)
2. Challenge (stock but without precats)
3. Top Speed (not equal length, tight primary radius)
4. Kline and IPE (short primaries, tight primary radius)
5. Agency Power/Fabspeed, and Tubi (good overall design)
6. Capristo (stepped primaries, better primary ID for power)
7. Supersprint (best on market to date, stepped primaries over a longer transition, superb merge, good primary length, increased ID post collector).

 

So ... if IPE lost power like in that thread, it means all 4-1 style headers will as they are very similar, no?

 

I will take my car to dyno before and after... enough of guessing.

 

So you think Fabspeed is better than Kline ?

 

Consider 4-1 or 4-2-1 to be a style, with good and bad examples of each.

Generally a well made 4-1 manifold is better for peak power, but at the expense of lower down torque. This is why the F1 V8 naturally aspirated engines used 4-1, as they were at high revs most of the time.

 

I do. Kline primaries are similar to Top Speed. Note the tight radius on the rear cylinder:

Note: I think the Top Speed manifolds are great VfM and still make more power than stock. It depends on budget.

 

This has been posted before but it makes sense...

Thanks, but here is top speed, same bend for the rear ...

Fabspeed also seems to have a larger radius on the individual lines, with no welding signs on them, i.e. no bumps in the flow

It does, but if someone is on a budget and wants to mitigate the risk of pre-cat failure then the $1k price does represent good value for money.

 

Regardless of what you fit, be sure they are insulated and not using that silly tape they wrap around the pipes.

 

Interesting you need extenders with these, yet you dont need with Capristo manifolds

 

I have a 360 but if I had a 430 I'd get the Supersprint stepped headers. Only reason I didn't get Supersprint for my 360 is because there are OEM catless 4-2-1 headers.

 

Supersprint look huge, not sure how they fit. ... Also the modified diameter on each line will cause a disturbance in flow for sure ?
