Everyone here seems to be very high on the EP product so I am considering it for a first mod. I asked Stef why they don't recommend the louder stage 2 for a 997.1 tiptronic and he advised there was drone from 2k-2600 rpm..which is a range where you find the tip car a lot in normal driving. My question is has anyone on the board put the stage 2 on a tip car and, if so, is it bearable? I don't daily drive the thing so I may just live with it but want to hear the thing first or get some feedback.

Also thinking about a Fabspeed X-pipe style as like it a little louder...but I assume that will be worse in terms of drone. Anyone with experience please set me straight here.

Also, are there any sound blips of the EP stage 2..I couldn't find one on EP's site.

 

two friends of mine are running with stage2 on modified tip cars and both are very happy.

I would say sound of tip car is so boring I mean it's like rubber from the panties so it needs more aggressive exhaust like europipe stage 2.

 

this is one of those cars:

There is a 997.1 with EP2 on TPCracing 997TTbblitzkreig light Europipe ehaust idling and revving (gold porsche) and this is with a warmed engine so sound is great.. The EP1 sound on the EPsite at idle is a cold start sound which imo is not so pleasant. I get no drone from my EP1 (manual), but as you say Stef says the EP2 because of the larger pipes (deeper tone) can give drone, he should be able to tell you about the real-world predicable-level too if you press him enough. I would think it would be low. There are a few 6-speeders with EP2 that should have reported on this "drone", if any, which should be in the historical archives.

 

What you say about mystical EP2-drone with the manual. Seems like lugging in manual 5th or 6th should be the same as the auto-tranny when the slush box goes into the lock-in converter or when the engine is going too slow for car speed and refuses to downshift.

 

But question is still unanswered, porsche turbo 997.1 or .2, with manual transmission, is there drone with EP2 ??

 

If you have to ask about drone, then stay with EP1. Everything about its looks, sound and performance is world class. Systems with 70+ mm pipes after catalytic converters will drone significantly more. EP1 is perfect for sensitive ears.

 

Buy the EP2L. You will regret anything else (except a custom EP prototype )

 

Another vote for the 2, I have th ep1, love it, could easily bump up on the noise scale a few notches.

 

I've had lots of exhuast systems over the years and they all have some sort of resonance - the question becomes is the resonance (drone) obnoxious. Even Corsa on an M5 droned and Corsa's claim to fame is no drone. B&B are the worst I've ever had both on a 350Z and a C6 but both were automatic transmissions. I'm on my second 997.1 TT, manual transmission and both have had EP2 installed. I drive highway speed 50 miles a day and at steady rpm in 5th or 6th there is drone but not obnoxious and I can still hear my radio and talk on the phone. I absolutely love the sound of the EP2 - I guess you figured that out since I'm on my second system. Drone to you may be different than drone to me (it's like tire noise) but I'm satisfied with the EP2.

 

I have EP2 with TPC headers. Very happy. Is there a noise that could be called "drone" at a certain RPM range? Probably. But its not annoying, only mildly different/worse that stock, and the rest is much better. It also seems like its either gone away with a couple k miles, or I'm not noticing it. Definitely a non-issue at hwy cruising speed.

 

My stock exhaust had more drone at 70 mph than either the cargraphic or EP1.

 

take stage 2 you will leave open door for future turbos tuning....

 

Thanks for the input...and especially to 997 GT3 RS/TT for the EP2 video...I know the EP1 is too polite for my taste so it will be EP2 if I go EP.

 

Either one would be excellent choices as both are extremely well engineered and manufactured to give genuine performance improvements, even without a tune. Based on your above comment I'm guessing you've driven a tip with EP1? Its no mouse when you get up it. As you've mentioned drone as an issue, if you haven't then it would certainly pay too before taking the EP2 plunge (imho). On all acounts EP2 is an awsome system but as Stef himself says, where drone is concerned it's not for everyone. For me, if the EP1 was any less "polite" there could well be problems particularly as a DD. Take that to the bank. And learning to "live with something" like drone has its price at one point .
