Best sounding exhaust

[Arith2]

I agree, the sound at wot was so intoxicating. It sounds awesome in the soundclip but even better in person. But that being said, i dont go ripping around the streets the whole time and the rasp was unbearable so i started putting on resonators and cats. Putting on the supersprint sec 2 xpipe this week and we'll see how it sounds. But honestly i might take off the cats and put on ar20s if it becomes too tame. That might be the right mix...i wanted the cpi sec 1 but couldnt find it anywhere.

I actually have one I'm not putting back on. Put like 8k miles on it if that. It's in my garage collecting dust.

That thing sounds so good...

That is why I love my GruppeM and get over the rasp. It sounds very similar. The Supersprint headers don't really produce a great sound versus a european style header. What got rid of my rasp almost completely was that CPI section 1. There's just a dead spot of power in the 2000s because of the early H. I had Megan headers, CPI Rasp Eliminator, stock sec 2, and GruppeM sec 3 and that is the best my car ever sounded. There is no performance oriented setup that will come close to how good it sounded.

The exhaust note is part of the engineering and appeal for the car. Going fast is fun but even Hondas can go fast. Everyone still laughs at a 500hp 1999 Civic because it sounds and looks like garbage.

I just got a newly released exhaust for the e46 m3 platform called valvetronic designs. I like that you have the ability to change the tone and loudness on the fly...originally i had just euro headers and this muffler which was super raspy with the valves closed but with them open at high revs it sounded like an f1 car! I added cats on the section 1 and it reduced a lot of the rasp but that high pitch wail at the top end was gone. I am adding a super sprint xpipe now to see if i could get rid of the rasp 100% but i miss the sound at wot with the valves open tbh. At least ill have the sound clip lol.

Glad this thread popped up I'm in the process of revamping my whole exhaust setup right now going with the following

Current Setup:
Active headers
Meisterchaft unresonated section 1
OEM section 2 w/ resonator delete
SS Race muffler

Setup that is on order:
SS V1 Stepped headers
SS 63.5mm Resonated Section 1
SS 63.5mm un resonated Section 2
SS Race muffler

I'm looking for a new exhaust because my exhaust note recently changed and the rasp has increased. Essentially my GruppeM is at the end of its life. I paid $600 and it's lasted 4 years. Good enough for me. The Supersprint Race came to mind as a similar Sec 3, but it doesn't have that titanium sound to it. I'm still considering it.

The Diablo was going to be my next choice until I found out those idiots purposefully created back pressure in the muffler. 50mm tubing according to their website. Back pressure is bad, especially on a performance oriented sports car. Then they had the audacity to post dyno sheets with their stupid exhaust.

While it hurts me to get a quieter exhaust, I'm leaning towards SS sport at this point. If AP still made their Ti, I'd be all over it.

Would the SS Race be louder than one of these titanium exhaust? I have SS V1s and stock section 2.

Actually Rogue Engineering has a 63.5mm Diablo exhaust coming out for E46 M3.

Installed Eisenmann Sport yesterday. So far so good- as far as sound the lows are a little lower, and the highs a little higher. There is a little drone over the stock section 3 on the highway at 70 mph, but it's not rude. Mated to headers, catted section one, and resonated X pipe, and Eventuri intake. I think it all sounds just right to my ears now. As it should after the money spent.

I concur. Though with a CSL intake it completely overshadows the exhaust sound so it's difficult to make out. But the rasp seems gone to my ears, not really any drone to speak of, and IMO the OEM S54 exhaust doesn't sound nice, now it does, but perhaps not "awesome". It sort of reminds me of the videos I've seen of Supras 2JZ now, which I admit is a weird association to have in a german car, but it's a straight six after all. I would be interested to get someone to do a driveby of my car so I get to listen to it from the outside. (CPI headers, Tegiwa 100 cell cats, Supersprint resonated x-pipe and Eisenmann sport, all stainless steel exhaust).

For me, not being a fan of the rasp, this would be the way to go, and just get a louder backbox for those wanting a louder exhaust, I fear a decat or a non-res section 2 would introduce drone.

I should say, he can sell the SS’s, after buying them from his competitor— ECS.

True but that makes it sound a bit different than why it is. He’s buying it wholesale from the Supersprint catalog like everyone else’s company price. He’s not really buying per se from ECS as a “competitor”. They as you know are just the NA exclusive distributor. Taking over after Turner acquisition who prior to that took it over from BMP Design.

But I would agree, his margins on his own house brand likely better than when outsourced from a distributor.

Anyway sorry for the tangent.

Across suppliers, the experience is consistent-- everything starts out built to spec, and then drifts, when they think you are no longer paying attention.

You could also be describing Supersprint here

I'm so proud of you guys.

I was getting worried when the apologists entered.

They have some top notch slave labor-- unrivaled labor prices in modern times.

... I work for a company that orders many parts from China (happily we're moving off that, finally). Bent and welded metal parts, so pretty relevant. Across suppliers, the experience is consistent-- everything starts out built to spec, and then drifts, when they think you are no longer paying attention. If you're Apple, sending 50 employees per day to/from China for QA, you can stay on top of them. If you're a normal company, far less likely you'll get as consistent of results.

The drifting quality when not being monitored piece of this was WAY more important than the country at issue, IMO. Germany is Germany in this arena because the quality standard isn’t quite so circumspect. My German performance car experience has always raised eyebrows when people chuck a bunch of Chinese and Taiwanese parts at German cars, expecting the car to perform the same. Huh? Who does that?

in other words, all the same issues there's been with china since day 1.

Hey now... threatening to nuke Japan was a new development.

Good times.
