Re: Exhaust Question - Supersprint or Remus While it's true that is almost impossible to increase the performance changing the mufflers, it is possibile to lose power. We have tested various setups and sometimes some designs (which are discarded) and some competitors mufflers are worse than...

Re: Exhaust Question - Supersprint or Remus Please specify the exact model and engine and I'll be able to advise you accordingly. Cheers.

Re: Any f30/f32 n20 running on thrum or supersprint exhaust? If you pick 987903 (centre resonated pipe) + 987906 (rear muffler with quad pipes) there's no drone, it's quite comfortable but with a nice sportier tone. Actually you could go for the centre pipe 987913 without much of a drone...

Re: Supersprint exhaust inspected & approved. BMW F12 / F13 650i V8 2011 ??, exhaust system Everyhing is in stock. I would suggest 986403 + 986426 + 986446 if you want a nice but midler sound with LTA approval, or replace the centre exhaust with 986413 if you want more sound.

Re: Supersprint exhaust inspected & approved. We're working hard to get some new mufflers with resonators to avoid the drone under 2000 rpm. We're testing on two cars: BMW M3 E92 (full system, it drones badly from 1300 to 1900 rpm) Audi A5 2.0 TFSI (full system, drones from 1900 to 3000...

Re: Supersprint exhaust inspected & approved. We're addressing the drone issue with the mufflers. The problem is that these mufflers were developed on the 550 twin turbo and then adapted on the *40 models, so we weren't able to test them in house. Please be patient while we find the best...

Re: Supersprint exhaust inspected & approved. BMW F06 Gran Coupè, performance exhaust systems Everthing is available exept for the rear mufflers for the 40i and the silenced centre x-pipe for the 50i, which are in production right now and will be ready the 1st week of September.

Re: Super Sprint Quad Mufflers For E92 335i If we make a centre exhaust with the same layout of the X3 35i N55 you'll be good, but there's not enough space under the car for a single pipe silencer. I think we'll use a design similar to the S5 3.0 TFDI centre exhaust which is very good for drone.

Re: Super Sprint Quad Mufflers For E92 335i One more thing. The reason why the Eisenmann drone less but doesn't pop is that the silencer is not a direct flow one but it's a chamber type. This means there isn't an uninterrupted drilled pipe inside but the pipe goes in, then stop, and a...

Re: Super Sprint Quad Mufflers For E92 335i If you'lll fit the centre silencer developed for the N54 you'll end up with a quieter system but I can't assure you won't have drone. We haven't tested the car yet. I'm trying to source a N55 engined E92 here in Italy so we work on it an find the...

Re: Super Sprint Quad Mufflers For E92 335i Are you even sure the Eissenman won't drone with your decat downpipe?

Re: Super Sprint Quad Mufflers For E92 335i You'll have even more drone. You'll need a classic resonator, a silencers in the centre pipe of the correct size. An alternative solution to erase the drone is to fit a blind pipe as a resonator, tuned for the specific freqency of the drone. You...

Re: Super Sprint Quad Mufflers For E92 335i On the S5 if you just change the mufflers there's no problem, but once you start to free up the exhaust you'll get a lot of it. Anyway, if I can help you with the modification, I will be happy! What kind of change do you have in mind? You didn't...

Re: Super Sprint Quad Mufflers For E92 335i Alvin if you want I can arrange a custom x-pipe with a silencer, that will erase the drone. I need to know exacly at what rpms it drones. Is it 1800/2500? We had a similar problem with the Audi S5 3.0 TFSI, that engine has like 3 different kinds of...

Re: Super Sprint Quad Mufflers For E92 335i The N55 drones a lot. We designed a specific centre silencer for the X3 just for that reason. We haven't been able to test our muffler on the N55 E92 sadly!

Re: Super Sprint Quad Mufflers For E92 335i Sorry I missed the detail it's a N55! Here are the ETK images of that model: The centre section is pipe only, so you won't get any increase in sound with the Supersprint centre x-pipe. The only way to increase the sound is to fit the racing rear...

Re: Hi from Supersprint - Italy Thanks! It's a very nice community.

Re: Supersprint exhaust inspected & approved. For your car? We haven't made them (yet), sorry! I was talking in general terms, with the 200 cpsi HJS cats that we use cars pass the MOT without problems. COx and NOx stay inside the limits, and the CEL doesn't turn on. About the legality of...

Re: Supersprint exhaust inspected & approved. If you keep the secondary cats or fit our sports cats you won't have the smell.
