fabspeed exhaust on 964

[wildman0609]

I'm thinking of getting a fabspeed maxflow system for my 964 race car. has anyone got any experience with these systems?

with the muffler in place is it going to be any louder than a standard system with a cup pipe and de-cat. my car is currently right on the 105db noise limit, normally a bit over. the last thing i want is to blow £2k on an exhaust then it be too loud to race.

i know fabspeed have a great reputation and love the fact it comes with a muffler bypass for the unrestricted days.

Rob,

I had the cat back MaxFlow dual outlet system on my 964 C4 and it sounded absolutely lovely. I got fabulous comments wherever I took it, but the downside is firstly, it LOSES power compared the the standard system and, secondly, the lowest noise reading I ever got with it was 108dB. It even got to 112dB on one occasion.

From a power point of view you are MUCH better off with a Cup pipe - exactly as Porsche used on the race cars. You don't see the Weissach engineers rushing off to Fabspeed do you??

I'm looking at getting the headers as well so am hoping that is where the extra power will come from. as the factory rsr's didn't have standard exhaust manifold with the heat exchangers cut off.

i'm pretty sure you can't get porsche headers for a 964 RSR any more so i'm sure fabspeed will be a good alternative. just a bit worried about the noise. and its worrying that yours read at 108db.

I'm not sure I concurr with your view that Fabspeed have a great reputation. For what ?
They might make plenty of noise, but most of their horsepower claims look to have been plucked out of thin air.

Tried and tested mods such as a decat and remap on a 964 seem to work well whatever the make of decat/bypass pipe used. I always viewed the Cup pipe as a weight saving mod as opposed to giving a Hp improvment.

I'd do some thorough research before investing your hard earned on Fabspeeds manifolds.

so who's manifolds would you consider? the FVD ones are practically the same, but the system doesn't come with a muffler bypass for the unrestricted days.


who makes the best 964 headers?

I think Porsche do! try 993 headers some people say its one of the main reasons the 993 has more power from the factory.I have spent a lot of time reading the American sites and it seems this is what they all say.
