Interest in Supersprint V1 & V2 headers

[ASAed330]

Not resonated. All ss sect1s have no resonators, Their sect 2s come with or without resonators.

You are correct, which is why I asked Alessandro to see if he can make some like their application for the E9x M3. He even pulled a new part number for this. However, since it is new, SS has been difficult to get ECS a cost on this part. Feel free to ping Supersprint to ask about 044022.

Although from what Matt has mentioned, it looks like it will be impossible to get non-catted Section 1 from SS.

Yes, it is a catless resonated section 1 made for the SSV1 headers.

How do you like the intake? I plan on buying one very soon.

Took a whole year to get right... mainly cuz the previous owner sold me the car that needed some fixing. I screwed around with 2 tuners that didn't really know what they were doing, but once I went to Randy it was all sorted and the car has been incredibly stable since going with his tune.

I have a ongoing joke with one of my friends to see if he can replicate the same gains with something cheaper. Honestly, it's a lot of money to get some cool noises... But one thing I will confidently say... Kabornious has excellent customer service.

That BW section 2/3 guts the bottom end and low mid range. Unless it sees no street use, better to go with the oversized SS twin 2.5" IMO.

Yeah it's 99% of the time on track, soon to be fully converted to a track car, so that's good to know.

[Obioban]

Can confirm. I have a SS V1 Stepped, but not the oversized header that's connected to the stock sect 1/2 and a Dinan sect 3. Randy at Epic was able to max me out at 329whp saying that the flow seems to have maxed out. I also run a Karbonius intake too.

My next config will likely be the oversized headers to oversized sect 1 into the BW race sect 2/3 setup to maximize the flow.

Stock section 1 probably starts to restrict at ~330whp.

I haven't heard a car with the oversized section and sport muffler in person, so can't comment on that. My guess would be that it still drones.

No disagreement. If someone is considering all factors, and maybe prioritizing some over others, what about a tone penalty with the reduced exhaust velocity as caused with the oversized section?

One of the commenters said they want to retain that raspy motorsport sound. I would guess part of that appealing sound is due to the higher velocity from the stock tubing. I think Tbone has previously commented on it after swapping around section 2's

[Obioban]

I would be interested in the V1 stepped headers + Oversized (2.5") catted Section 1. Thank you Obioban for the explanation. Will stock Section 2 work with Oversized (2.5") catted Section 1?

Yes, and if you're not doing the cams/airbox thing you won't be any worse off. If you do go that route, you can always do the oversized section 2 later.

[Obioban]

For a baseline comparison, what power levels does the stock, resonated section 2 becoming a limiting factor?



With section 1 cats and section 2 resonators, does Sport still drone a noticeable amount?

There will be no uncatted products unfortunately. Is the 5) a catless resonated section?

Would have to be as there isn't room with the cats that SS uses.

thanks a lot EPA… 😒

[Epoustouflant]

There is also a new part I asked Alessandro if SS could make and he gave a part number, but there has been no cost provided to ECS yet. Part number 044022.

Section 1:
1) Normal sized catted. Works with any normal sized header (not V1s). Uses HJS cats, so holds up to the heat of track use.
2) Normal sized uncatted. Works with any normal sized header (not V1s).
3) Oversized (2.5") catted. Only works with V1 stepped headers. Uses HJS cats, so holds up to the heat of track use.
4) Oversized (2.5") uncatted. Only works with V1 stepped headers.
5) Oversized (2.5") resonated. Only works with V1 stepped headers.

I'm going to attempt to summarize the entire SuperSprint line to clear up confusion...

Section 0 (headers):
1) non stepped headers. These were the first SS e46 M3 header, and are what basically every good ebay header is a copy of. They're fine, but there's no reason to buy them since SS's released their step header line.
2) V1 stepped headers. These are the best headers on the market for the car. They make some of the most peak power and do so without trading off the midrange or bottom end. But, they require a bespoke section 1 to work (adds cost).
3) V2 stepped headers. These are also stepped but, shorter and not oversized. They don't have the peak power potential of the V1s (which really need cams and airbox to be fully realized), but the are still good in the bottom end and middle range. Works with any section 1, including stock

Section 1:
1) Normal sized catted. Works with any normal sized header (not V1s). Uses HJS cats, so holds up to the heat of track use.
2) Normal sized uncatted. Works with any normal sized header (not V1s).
3) Oversized (2.5") catted. Only works with V1 stepped headers. Uses HJS cats, so holds up to the heat of track use.
4) Oversized (2.5") uncatted. Only works with V1 stepped headers.

Section 2:
1) Single tube unresonated. Good till ~300whp. Light.
2) Single tube resonated. Good till ~300whp. Light.
3) Twin tube (2.5”) unresonated. Good till ~400whp. Heavier.
4) Twin tube (2.5”) resonated. Good till ~400whp. Heavier.

Mufflers:
1) Street. Similar volume to stock, but nicer tone. Zero drone. 2 lbs lighter than stock.
2) Sport. Louder, drones. 15 lbs lighter than stock. Probably the volume level than most people looking for an aftermarket muffler desire.
3) Race. Fuck you loud, drones. 25 lbs lighter than stock.
All mufflers above can be custom ordered in 2.5" internals. This is only beneficial for all out builds (not the normal cam/airbox/exhaust builds). Does add some weight. If you're doing this, you can also custom order a twin tube section 2 to match, so that it doesn't neck down where they join.

Notes:
-Street, sport, and race mufflers all flow identically.
-resonators also don't impact flow.
-if you want to eliminate drone, you need cats and resonators.
