  • Exhaust or carbon airbox

    So what would is best investment for increased enjoyment? Not really after more pace per second but more adrenaline from sound and feel?

    Assume eissenman exhaust and evolve airbox....

    Do you know if Evolve are still doing their box as couldn't see it on the site the other day?

      They contacted me to act as a guinea pig for their S54 design to see how it would fit / work on a Z3 but we could not agree a price I was happy with.

      I'm not sure they ever finalised one for the Z3. Decent guys though so it's free to ask ;-)

      Personally I would get the eisenmann but the big question would be race or sport, how loud do you want. I have race which is great but not sure I would like it on a car I drove a lot ?

        Just how loud is the race? Is it really Ferrari sports exhaust loud?!

          I would get a "Prospeed" exhaust custom made for your requirements (proven power gains and much cheaper than most others) wouldn't bother with a airbox but would suggest suspension mods instead

          (Kwv3 or similar) if you haven't already Evolve can do carbon airbox's for the S50 and S54 M Coupes but not cheap.

            Exhaust wise I would go with a supersprint, they give powergains where as the eissenmann do not . They are also a lot lighter.

            The supersprint for me also wins over the prospeed because if I ever decide to put it back to standard the supersprint would be much easier to sell on rather than being a bespoke item and the associated variance in build and sound.

            Btw not knocking eissenmann or prospeed both good systems and a big improvement over standard just giving my rationale for deciding to buy a supersprint.

              Another option is to have a standard set of back boxes modified?

                .
                think you will find Eissenmann do give power gains.
                Not sure which is the lightest of the 2 but both I wold suspect would be tons lighter than standard

                  I would say the eissenmann is lighter than stock too, I have my standard ones in the garage and they way a ton.

                  Going from my research, most of it on here, pointed me towards the supersprint for power gains and mac motoren run them on their own m coupe which is a good endorsement. as i said before not knocking any of the other systems out there all have pros and cons.

                    Without measuring I would say not much in it compared to an F430 in Race mode.

                    The way I usually describe it is people look back when they are in front of you a few hundreds metres and SWMBO knows when I'm nearly home 1/2 mile away in summer with house windows open.

                    Not boomy though, just loud.

                    A common cheapish mod on the 993 is to have the sound deadening stripped out of the mufflers/silencers (referred to as RSR mufflers) which gives a great throaty burble but not sure how a straight 6 would compare to the 993's air cooled engine doing that ? May be worth a try if your going to change anyway as the old ones are hard to shift ;-)

                    For what its worth here is an extract from my 993 journal....

                    1. Stock OEM mufflers
                    2. OEM RSR Mufflers (nb OEM big oval exhaust tips added but they don't affect sound).
                    3. OEM RSR Mufflers and remap

                    1. Stock OEM mufflers



                    2. OEM RSR Mufflers (nb OEM big oval exhaust tips added but they don't affect sound).



                    3. OEM RSR Mufflers and remap



                    The exhaust sounds tinnier on film than it does in real life as cameras struggle to pick up the base notes but you get the idea. After the remap the exhaust pops and burbles a lot more freely. Its great in traffic in 2nd gear and awesome under load when accelerating :thumb:

                    nb the Eisenmann on my Roady are louder but you don't get the crack/burble of the Porsche air cooled ;-)

                      Air box all day long , hitch a lift in a csl , you'll never consider exhausts again .

                        I got an Eisenmann Race fitted last year and in all honesty, I've been a little disappointed with the noise....

                        I am by no means an expert on exhausts, this is the first time I've ever put an aftermarket exhaust on a car but the one thing I can tell you is in my opinion it sounds nothing like a Ferrari F430 having heard a few of these going round Knockhill.

                        Initially I feared the Race version was going to be too loud but as I only use the car for the odd blast now and again and after a few people also said it wasn't as loud as its made out to be I went for the Race version. I did a search not long after I fitted it and found a few people out there who had actually returned theirs as it wasn't loud enough. I'm sure the guy at CA said it takes a few miles of wear before it really starts to sing but I've done about a 1000 now and I wouldn't say there's a real difference to when it first went on.

                        Don't get me wrong, although I'm a little bit disappointed with the sound it does still put a smile on the face when climbing up the revs.

                        I heard a video recently that was posted on the forum which I thing had the standard S50 mod and to me it actually sounds better.

                          One of the deciding factors when I went for Race was watching a YouTube video with a Z3M (sure it was a forum members car) that had the Eisenmann Race but also an aftermarket Airbox - it sounded immense, the sound I wanted.

                          As you say its obviously the Airbox that really makes the sound.

                            This is the part that is so hard picking anything like an exhaust, one man's loud is another man's raspy, especially when a second hand set is going to cost the best part of £1k

                            It took me a while for SWMBO

                              I have both an Eisenmann Race and a Carbon Airbox.

                              For me it would be airbox all day long. Much higher grin factor.

                              Completely agree with what was previously said about the 'race' not being as loud as I expected.

                              Have a look through my youtube channel for a few videos to give you an idea of sound.
