This has the following exhaust on it from what i was told by the owner in a facebook group. https://www.gwapotech.com/product-page/ferrari-360-modena-f1-sound-valved-sport-exhaust-system I believe it's a Euro car and the factory manifolds and cats are still on it from what i was told. Although, it seems a bit too rowdy to have factory cats still in place. Take that info with a grain of salt. Doesn't sound too bad honestly. I'm looking pretty close at the whole setup here for my own car fairly soon.
Here’s a Scud with Full Kline Inconel. Says he has cats, but not sure if 200 or 100 cell. My setup with Capristo headers + 100 cell Kline Inconel (or straight pipes) + Kline Inconel muffler sounds better imo. Cleaner and more F1 pitch from start to finish. The Kline headers appears to kill the F1 pitch from low rpms and only begins to have some semblance of F1 pitch at higher rpms. Sounds more grunty down low and not quite the full F1 pitch when it finally gets to the higher rpms. My setup takes this setup with ease. * Side note. There was only maybe a 10-15% sound difference between Kline 100 cell Inconel cats and straight pipes.
Some combinations just seem to pair up better. For example… perhaps Kline manifolds + S-Line is super fantastic, but Kline manifolds + Kline muffler will not quite get you there. Then you have different cats to throw into the mix. I’ve always been curious about the Pogea Racing muffler for the Scud. Appears to be a potentially louder Kline. Or even Valvetronic Designs. Smaller muffler box.
any vids of your setup? He has 100 cell cats I believe. The only diff between the two setups would be your headers which are steel and 4-2-1 headers vs his inconel 4-1 headers.
The difference in headers would make all the difference imo. No vids unfortunately, but I can tell you it’s different enough. My car is also running straight pipes now instead of 100 cell. Almost same sound as 100 cell. Probably only a 10-15% volume improvement. I ran the same setup as @RichardCH . Capristo, 100 cell Inconel, Kline Inconel muffler. It appears he took the vid down? https://www.ferrarichat.com/forum/threads/scud-video-kline-inconel-x-pipe-exhaust.499691/
Capristo headers are basically a louder more open OE header imo. I ran Capristo headers with OE cats + OE muffler for 1000 miles or two and it just sounded like a louder Scud with more balls. Here’s a vid of Valvetronic muffler , straight pipes, and OE headers. You can already hear the F1 pitch from start to finish. I actually think this muffler box is better than Kline’s after listening to it a few times. Sounds louder and a bit more wild. More to my liking. I’ve always said Kline sounds great… just not loud enough. A capristo header added here would only make it louder without changing the pitch type you hear.
Cap headers, cap 200 cats, kline muffler on my 430 sounds pretty insane. Top speed headers, top speed 20o cats, kline muffler on my 360 is bananas
that’s what’s surprising to me is the 4-2-1 header layout providing the higher pitch than the 4-1 layout of the Kline. From a sound perspective, I was under the impression than 4-1 headers typically provide a higher pitched sound than 4-2-1. I recently added Kline 4-1 headers to my scud that already had Kline 200 cell cats and s-line xpipe (non valved). The 4-1 headers changed the pitch of the exhaust as soon as you get onto the throttle from idle compared to the stock headers. The stock headers (4-2-1) had more of a “boomy” sound off idle whereas the Kline headers added this higher pitched “whirl” off idle.
There are different types of 4-1 headers. AP isn’t the same as Kline. Kline isn’t the same as Powercraft. The variances give different results. However, my comment was more towards the synergistic result of a particular combo. If you feel it worked better with S-Line, that’s great. There have also been people in the past who felt Capristo headers + S-Line was also great. The results of Kline’s 4-1 header + Kline muffler are in that video. To my ears it sounds grunty like a standard Scud at lower rpms, then suddenly changes to F1 pitch last min at the higher rpms. I’m not hearing a smooth, clean, defining F1 sound from start to finish. The F1 sound build up just isn’t there like other samples. On a side note, I would say there’s no boom at all with Capristo + Kline combo. Fwiw, most 4-1 headers on a 355 have killed a good percentage of F1 pitch on a 355, so it is possible.
Here’s another example of full Kline Inconel. Not sure if he’s running 200 or 100 cell, but results are similar to my ears to the yellow Scud. Does this not sound like a louder standard Scud at the lower rpms?
I guess sound is so subjective. For my ears, all of these exhaust videos that use a X pipe setup don’t get into the high pitch sound until 6k rpm. For me, the “high pitch” sound has its own spectrum that ranges from more of a throaty high pitch sound at one end, clean high pitch sound at another end, and a more raspy high pitch sound in the middle. Where you end up in that spectrum is dependent on the particular combo.
I’m not so much referring to high pitch F1 sound at lower RPMs, but there is a subtle F1 howl you can hear that is distinguishable from a stock exhaust. That howl simply picks up in volume and starts screaming at upper RPMs. It’s the subtle F1 howl and build up I am referring to. Here’s a Fabspeed, straight pipe, Kline F430. You can hear the subtle F1 howl at lower rpms. I guess those who have the same setup with Kline headers need to ask themselves if that subtle howl is there at low rpms. Here’s another F430. Not sure his setup, but it might just be stock with a Kline muffler. The F430 with AP headers + Kriessieg muffler I drove was F1 howl from start to finish. Even more so than my setup. Of course a valved x pipe isn’t going to start screaming at low RPMs, but it needs to have the subtle F1 howl to build into the F1 scream.
Here’s an example of a Brilliant X-pipe muffler from Japan. Description only mentions muffler (not full exhaust), so I’m going to assume the car is still running stock headers and possibly stock cats. @6:40 Perfect example from inside the car of subtle F1 howl at low rpms leading into higher f1 pitch.
We are on the same page....what you are referring to is what I've described as more of a "hollow" sound that builds into the F1 pitch whereas some other exhaust setups have more of a bassy note that leads into the higher f1 pitch. I'll be heading to Laguna with my Scud in July and will have my Go Pro mounted. I should have some good footage from the event to contribute.
Sorry, been quite busy lately! ShineKen has just posted the video I shot with my car, you can watch either with subtitles or with the weird AI english audio track That's me ahah! I'm running with 100cell. Absolutely love the new soundtrack, it sounds mega when you hear in real life
