Can you guys who have the fabspeed tell me what you think of them. I have a brand new gemballa system that is not working out for me and i need tog et rid of it and buy a new one. You think the 110 mm gemballa tips will fit on the fabspeed system bc i really like them? How loud is the fabspeed? are the gains really as stated? hows the sound? anything would help, thanks in advance.

 

I have had my fabspeed about a week and a half, it was loud when I first got it, and Im prolly used to it by now, so it seems that it isnt too loud. Very throaty sound, rumbles at the light, get attention from other drivers, and plus the night I installed it and took it out for a test run, I got a thumbs up from a sheriff. HP gains are minor if any, just sounds real full.

 

you sure there isn't something wrong with your car? i've never heard of mufflers causing a car to run improperly.

what exactly is your car doing with the gemballa mufflers? quite honestly, mufflers on a 996 don't do much more than change the sound so i can't imagine them having a negative effect on performance.

have you tried switching your cans back to stock to see if your "problem" disappears? that would be the true test.

 

Nothing is wrong with the car, and nothing is wrong with the exhaust either. My Porsche tech ran the whole 9 yards in diagnostics, clutch, etc, etc, etc and found nothing wrong at all. Says sometimes a car does not like to adjust to an exhaust, so I figure ill get something else. What do you think of dansk? evo ms exhaust?

 

have you tried putting the stock exhaust back on to see if it does the same thing?

i could see if you did headers, cats, and mufflers, but it just sounds kind of bizarre that your car would not run properly due to mufflers.... i think you're the first person to ever post anything like this on here. i saw your other thead about this problem and you state the car drops 200 rpm and then surges back up when you got WOT from almost any rpm.

have you tried disconnecting the batter yet? i seriously doubt it as mufflers offer almost no HP gains at all, but maybe the ecu needs to adjust. something is not right with this. i would swap back to stock and see how it runs before you proceed any further and lose money on your exhaust system.

exhausts are like colors. everybody has a favorite. go listen to them at a pcar event and then make your decision. i would still make sure you diagnose the problem with your car before you buy anything else. it would be a shame to lose the money on the gemballa, buy something else, and end up with the same problem.

unless of course you just don't like the way the gemballa sounds...

 

Im not too happy about it either, because it sounds amazing. throatier, deeper, and just screams 5k and above. Im going ot put the sotck exhaust back on prob today or tomorrow and see if it goes back to normal. I did reset the battery, but to no avail. I might do dansk headers tho, what intake does everyone like on here? I also have Porsche drilled pedals coming, i hope they get here soon. Other than that im gonna get the car dropped with H&Rs and be done.

 

I just reinstalled the stock exhaust, and the same thing is happening. I have no idea what to do now. Porsche says everything is ok with the car, so you figure to put the stock exhaust back on and it will go back to normal, but it doesnt. Any suggestions?

 

yes, take it to a different mechanic. there is something wrong with your car and your guy obviously does not know how to diagnose it. might as well keep that exhaust too, cause that is not the problem.

maybe fouled plugs, who knows?

 

Yea, i doubt i will let it go now. I just cant wait until this problem, whatever is it, is fixed. from what ive been told, it could be my spark plugs or the MAF.

 

Do you have a tester? Check Engine light on?
to rule out MAF, you could just remove it, clean it with good electrical cleaner (let it fully dry) and reinsert it. If you disconnected the battery, you've got some miles to put on it in order to get the sensors and idle adjusted to norms. I have an occasional P1034 code that trips the ECL and after I reset it with my scan tool, car feels loggy and like it is going to stall (which it never does) for about 15 miles or so, then it's "learned" me and is back to its old self.

Exactly right and on the money, and something i have been telling him repeatedly! Weird how you want to dump the exhaust for so cheap and move onto another exhaust so fast, meanwhile your car is having the same prob's with stock exhaust back on! Get it checked out again man, something is up

 

I dont want to dump the exhaust because i love the sound of it, forget about gains, i know they will be minimal, but even the cheap price i was trying to get rid of it for did not spark the interest i would have liked. but anyway, im going to keep it until i figure out whats going on. I will be contacting porsche 1st thing monday morning. Weird thing is, no CEL light, or any other light or code to even tell me something is wrong. Within the last year, i had a CEL come on, i used fuel injector cleaner to see if that could have been it, because i know of someone who had the same problem and the CEL light went out after that. then it still didnt go away. it was the MAF, and I promptly had it replaced. I would like to think it wouldnt be that again, but at this point im not ruling it out. its hard tho when porsche runs every test and diagnostic and finds NOTHING! wish me luck that this gets fixed.

 

I don't know what your symptoms are, but the dealer or mechanic sounds like he needs to go. On my recently departed 996, I had a problem with the CEL coming on and off and the engine sounding/feeling terrible. Some days it would work, other days it wouldn't. Took it to a local dealer and they said it was "bad gas" and I put in all the products. This worked for a weekend, then the problem came back. Took the car back to the dealer. The dealer said they "couldn't replicate the problem.... That was the end of that dealer (I was not very PEPE after that, ). So, I went to a different dealer who called me back before I got home. At first they didn't believe me that I took it to another dealer. They said the tech found the problem just by turning the car on.... It was a bad coil. Not sure this is your problem, but taking it to a different mechanic can make a world of difference.

 

Here is something supd to try out because your rpms have dropped about 200rpms. make sure that your air conditioning is on and that the fan is on say three or four bars, my 911 does the saem thing when the aircon is off but as soon as I turn it on the idle raise to ~900rpm instead of 700 or so after it warms up and everything is fine.

 

It is absolutely typical for the RPM's to be higher with the air on....it is
supposed to do that.
