430 4-1 headers and the noise they make?

I have Agency Power headers installed and i have the same sound. Low rpm growl but sounds better at higher rpms. Its not really the sound i want but not sure what else to do

 

That appears to be the penalty of the 4-1 versus the oem 4-2-1 designed exhaust manifolds, at least when used with the factory oem or some aftermarket exhausts. I will say that with some others, it can still scream like a banshee, even with 4-1. Check into Kline or S-line.

 

I have Capristo 4-2-1 and really miss the power delivery and sound of 4-1. This winter I'm going to sell the Capristo manifolds and go with Supersprint 4-1.

 

what other exhaust do you have with the cap headers and do you have high pitch sound

 

I think that is the trade off. I have AP headers and s-line, it sounds like an old school high pitched F1 car. I would not say at all it has any resemblance to an American V8 at any RPM level. However there is a small drop off in performance under a tiny RPM range in the power band.

So 4-1 sounds better, 4-2-1 for all you can get out of the engine.

 

To the OP, same thoughts here with my fabspeed headers. Am also curious if different headers with the same exhaust after the headers produces noticeably different sounds.

 

My CS has fabspeed headers, high flow cats and Capristo sound 3 muffler. I get tons of positive comments on the sound. Not a single negative.
If I’m driving around “normal” mode I get a drone right before each shift. Drive aggressive and it screams. Start up , hammered and idle sounds great. No drone while cruising, as long as I’m not higher range in a gear. 4500 rpms -ish seems to be drone range.

 

I have top speed with stock exhaust and get nothing but compliments on the sound. I think they sold like 6 pairs to people I know just based off the sound of my car.

Some cars have a different sound then others for some reason. I have a 05 and it sounds different then his 08.. he has since added s line and likes the sound better now.

 

Valve timing can change the sound significantly, even with the same exhaust. When you replace belts degree the cams and you will likely hear a pretty significant difference in sound. Kind of makes the hunt for the 'perfect' exhaust a bit of a mute subject until you have degreed your cams.

 

A 360 and a 430 will sound different even with the same set up so we have to be specific which cars were talking about

 

Yep, very different

 

If you have an F430, talk to mwstewart and see if he will sell you his Capristo exhaust manifolds

 

I have top speed headers without the drone because I have an x-pipe in my exhaust routing. What you need is an x-pipe. An x-pip will get rid of drones in Ferraris, LSx motors, and other cars. Some Exhaust systems has an x-pipe in them, such as S-line and IPE. Other's do not, like Tubi.

 

Drone is created by the resonance during a certain RPM or frequency that is created. Yes, on most cases a X-Pipe will help get rid of the drone but the amount of exhaust talk/crossover defines that. The 430 in general is known to have that throaty V8 sound in the low RPM and screams when you kick it into gear. That's just the personality of the vehicle and how it performs versus a specific exhaust company. Point being that exhausts without an X-Pipe and with a Muffler will not always drone.

 

Get turbos

 

I can definitely point him in the right direction for that!

 

I've heard them all. And I agree with the OP ...... they ALL sound "cheap". (doesn't sound like a Ferrari)
Nothing sounds as good as OEM.
