S-Line X-Pipe + Capristo Headers on a Scud

There is a chrome ceramic (cermakrome is one) available also that is high temp (up to 1600F) - ends up looking like polished. Something to consider. You might be able to overnight it out and back with not too much downtime. That is what I would favor since the exhaust is so prominent when you open the engine cover. No experience with it first hand though.

Exhaust wrap looks mean though; will match the centerlocks, challenge wheels, and lack of floor mats ; )

 

Any pic of the ceramic coated x-pipe?

 

Here's mine, becoming more and more bluish/purple everytime:

I love my purpling, polished pipes.

I am running Capristo blankets only on the headers & cats.

 

bumping this old thread just to add my experience. I have the s-line xpipe on my scud along with 200 cell cats. I've tried both capristo and fabspeed headers with this setup so wanted to share my findings.

capristo:

- more gurgle off the line and bassy <3k
- drone right around 2.5k
- clean mid/upper range sound
- more overrun sounds when letting off gas & shifting (pops, burbles)
- PITA to install/remove

fabspeed:

- bit less bassy <3k rpm
- less overruns sounds
- slightly less drone, but more tolerable/less intrusive since its lower in the rev range (around 2k)
- rougher/buzzier sound from 4-7k. Sounds like engine noise is being amplified. Especially noticeable as revs winds down when letting off gas.
- slightly louder and higher pitch near redline

So both have their pros/cons. These observations are from inside the car and my feeling is that from outside, both setups probably sound very similar. Both retain the overall high pitch tone of the s-line. I didn't really notice any power/torque difference between the two. Quality and fit for both were very good. Still deciding which way I'll go but leaning towards the capristo.

 

Best Scud sound I've heard! Fresh, you track your Scud yes? How did the 100 cell cats hold up to track duty? I know a lot of 200 cell cats are "not for track use".

I need new RSC1's and MPSC2's but my next $8,000 pot of gold will go towards Capristo headers, blankets, 100 cel cats, S-line, and Zeus tune.

 

someone may consider tp go with cat-delete pipes or high flow cats before you go with headers. It will make the car lauder for sure.

I'm considering same set up for my car but i think i will go with capristo headers, catless pipe and s-line.

 

Great post. Just the type of feedback I've been looking for.

Koop is right about the Capristo Headers (+blankets) being a pain in the ass to remove and install. My mechanic probably took 5-6 hours and most of that time was trying to figure out the best way it would go in. He's also had a ton of experience installing 4-1 Headers including fabspeed, Agency Power, IPE on multiple 430s. He'd kill me if I asked him to remove the Capristo headers lol.

Koop. Any particular reason why you chose to try Fabspeed headers over the other 4-1 Headers? From my experience driving an F430 with AP Headers, stock cats, and Kriessieg Muffler (run w/ open valves) there were a ton of pops and burbles in all rev range... Including low 1k rpm. Car felt surprisingly torquey as well. Could be the Kriessieg muffler or the headers... Not sure.

Freshmeat's setup is IPE 4-1 Headers + 100 cel cat + S-Line and with you reporting hearing less overrun (pops and burbles) could indicate the header piping diameter could be slightly different. IPE and Agency Power might be slightly bigger. If someone can verify this, that would be great.


There is one thing I notice people not really noticing in regards to X-pipe exhausts for F430/Scuderias. The loop configurations are different.

The S-Line loop configuation on the F430 is different than their version on the Scud. The F430 version loops going further out and then coming back in much in the same way a Kriessieg or a Kline does. Freshmeat pointed this out before but not sure if anyone picked up on it. Could this be the reason why the Scud S-Line sounds more F1 than the F430 version? What's weird to me is the Kriessieg muffler on the F430, which loops the same as S-Line (F430 version), sounded pretty damn F1 high pitch in person. I wonder if that has to do with some of the exhaust gases flowing through their specialized muffler to produce a certain type of sound.

The S-Line loop configuration on the Scuderia starts in and then loops out. Hard to describe but pictures would point out the obvious. This is probably the only exhaust for the Scud that loops this way. Kriessieg and Kline are not the same and I am not sure how much these looping differences contribute to sound differences.

 

Koop. One more thing. You mentioned you didnt feel much of a power difference between the headers. Have you done the Ecu reset procedure?

 

ShineKen, that is my 2-setups-ago setup =) Check your txt msg's.

 

Shineken- I'm just not a big fan of AP products. Most of their designs are copied off others and everything is made in china. I also got pretty good pricing on the fabspeed headers through Yellow compass.

Decided to go back to the capristo though. I really don't like the midrange sound of the fabspeed... seems like I'm hearing more engine noise than exhaust and its not exactly a pleasant sound. I didn't do any ECU reset.

I think if you want really high pitch you should just buy the kreissieg from freshmeat

 

I don't think Kreissieg has higher-pitch than S-Line, freshmeat has been trying to sell his Kreissieg for the past three years I think

 

Kreissieg and S-Line pitch is fine with me. I guess I'm more concerned about drone at this point, so I might lean towards Kreissieg.

 

Yes, Kreissieg is not as high pitched as an s-line.

The sound "thins out" on the Kreissieg at higher rev bands, if that makes sense, similar to how some modded 458s sound; the sound becomes a hollow / synthetic noise.

Because it's a valved system, it also weighs a ton and a half and alarmingly retains more heat than oem...that's when I guess I realized the "not for racing applications" sticker on the box made sense lol. imho those looking for a valved system should try out k-line. Inconel offers massive weight savings! Though I cannot vouch on how it sounds or how much heat it retains because I have never heard or seen one in person!

My Kreissieg system has been retired into a form of display case coffee table which will be the center piece of my mancave once home renovations are underway. I think it will go nicely w my Scuderia striped racing emotions egg seat

 

So after having the capristo headers put back on, I've managed to do some more miles and take some more mental notes. For starters, the capristo headers definitely have a much cleaner sound w/ the s-line compared to the fabspeed. It's still high pitched but much smoother without the excessive engine valvetrain noise. The capristos also have more occasional loud pops (like gunshot loud) on deceleration and downshifts. Additionally I can now say that I do feel a slight difference in power/torque between the two. The capristos seem to be more linear where as the fabspeed had a bit of a drop in the midrange.

Overall I'm happy now with my setup. I know that some people prefer the 4-1 headers, but I think there are tradeoffs to both designs. It would be great if someone was able to dyno both setups and get some hard numbers.

 

Who makes a good 200 cell cat for Scuds? How about the 100 cell option? And will either the 200 or 100 cell cats throw any lights?

 

I have 200 cell capristo cats and yes they did throw a CEL. I was able to fix it with some L shaped o2 spacers.

 

Here are my "gunshots"...and not even 20mph:

At highway speeds my "gun shots" are even louder and sound more like "canon fire", people behind can feel the sound through their windshield...Capristo's 4-2-1 dirtier/gurglier sound + droning in the lower rpm's probably resonates at the same frequency that "masks" the sound of your valvetrain I guess, because that valvetrain noise is always going to be there irregardless of what you do to your exhaust. The capristo sound only cleans up after 6k rpm, which by that point will sound similar to a 4-1 layout.

As for loss of power / torque in the mid-range with 4-1, I refuse to believe it until someone throws up a side-by-side dyno because that theory has been disproved multiple times and the butt dyno is as accurate as my farts

Skip over to 3:02, watch this guy's reaction after following me for a good while...oh ya, more "gunshots" at low speeds without any of those gurgles / sputters.

Sounds awesome freshmeat!

My experience is different than yours, quite possibly due to the different cats and maybe even due to slight differences in the way the fabspeed headers are manufactured vs your specific brand. You also have a tune which may change things slightly. I noticed drone and "gurgling" with both fabspeed and capristos, but the valvetrain noise was very apparent with the fabspeed between 4-7k. It's still there with the capristos but its not over-amplified and mixed into the exhaust sound. The drone only exists around 2-2.5k so its definitely not masking anything.
