After Market Exhaust and Tuning

That is a question I can reply in all honesty. Some time ago I was driving my car on a road I know well and noticed how my car revved so free. Completely forgot about the exhaust and wondered what made the difference. And of course, after some more miles it hit me I had a new exhaust installed. So, really, the difference is very noticeable.

I like the EP1 too. It is trouble free, like no engine lights, no drone and no requirement for flash. However, just Heard a sound bite with a '07 turbo with a GMG exhaust. I think it sounds a little deeper than the GT1, if fact a lot better for me anyway. Do you know if the GMG is as trouble free as the EP1??

EP1 in the first place. Still think the GMG has that 4me desirable deep V8-like rumble (single sound clip), better tone than the hollow tankish-6yl-tone of the EP1, but if comes with "headache factory issues," I'll stay put with my headache free EP1. I'll keep searching for more sound bites.... those GMG issues, where they seen on this website or 6speed or both

That's why I was asking. Your's/surgeon's influence brought me to the

The EP1 doesn't have either of those issues thankfully or it was back to the stock exhaust for me. As drone is an issue, another possibility for you (may) be that new Kline system but imo there isn't enough feedback out there at the moment to qualify whether it has a guilt edged guarantee of being drone free. It may be, i don't know. I hear it at least adds performance without the need of a tune so it's obviously had some thought put into it unlike so many other systems out there that make fanciful/false claims and rely on sound clips as lures. You mention a tankish sound? I'm lost with that. I've never had anyone say anything other than how awesome it sounds from the outside. Are you referring to when the cold start function is running?

The gmg doesn't drone, just very loud.
Tom, I find that drone and resonance comes from modular exhausts with multiple clamps and joints. These will all eventually loosen and drone on a tt.
The two can system was one piece with absolutely zero drone, unlike the new one can multi vband tubi that drones like ******.
The EP is one piece= no drone, Ruf one peice= no drone.
If it has clamps it's gonna drone.

Different then what is shown on today's market. When did tubi change their design.

EP2 has no clamps, is one piece, but drones. I suspect various factors such as pipe size, muffling material and design and the mufflers general capability to arrest sound would be the prime causes. Maybe Stef can chime in to give his explanation why he is unable to get his EP2 drone free?
Chris. I accept loose clamps (may) enhance an existing droning exhaust to drone more but in so far as to state that is the sole reason for a system to drone is illogical.
With all due respect I'm not saying you guys don't know what you are talking about re the 2 can, or any other system you say you've heard that doesn't drone, just that i was informed by one of the forums most respected vendors who specialises in modifying Porsches, who has sold and fitted both types said it does and, that it is not as good as the current single can version.

I've read users say the system does drone, enough to remove it. It is a loud system that drones.

So Tom is yours a two can or a single can?

Agreed.. My Techart does not drone and it has clamps..I have had many passengers in my car. Never complaint about unpleasant exhaust note or resonanace. Interior noise is very docile.. It has a very nice growl at WOT..I have heard many systems and not one of them have I hated.. "Ear of the beholder" ...

Just to chime into this EP thread. I have owned 3 other normally aspirated p cars before my current 7tt.1. Two of those were 997 CS and C4S cab with factory switchable PSE. These were in "unplugged" mode 100% of the time as I loved the noise. My first p car was a 987 boxter s and soon bought a tubi for that and only put up with droned headache for 2 weeks before a returning for a full refund. That exhaust sounded great on youtube and in real life outside the car, but was hell to live with. I love loud but tune-full exhausts having owned 3 v8 sports cars in the past (TVRs for anyone who knows what they are!). Really missed the noise when I got the 7tt and started hunting for aftermarket alternative. Many hours of listening to videos and reading threads like this led me to Steff and Europipe stage 1. Firstly, the customer service is simply astoundingly good. The product and packaging is superb. Fit and finnish is better than any oem porsche part. This is as good as it gets and the sound is spot on, inside and outside the car. I am 12 months into EP ownership and still makes me smile. This is not the loudest tt exhaust in the world, but it mixes its own muliple tones with turbo spool noise (not just rushing air blast) and a flat 6 distinctive noise that I think is as close to the noise a factory 7tt sports exhaust would be if they made one! No, its not a gt3, but its damm good for a turbo car. Real character as opposed to just loud and throws in a bit of extra turbo torque for good measure. You might get the feeling that I like it

Another Happy customer! That's awesome..It's nice that there are "Europipes" out the there to diffuse all the crap that people try to sell us (and I don't even own an EP lol!)

I have the two can drone or not I'm content with it. A few weeks ago Art, myself and another 6 speed member went for a ride and swapped cars. We did several pulls past one another, at WOT honestly they all sound the same, WHOOOOOSH. I think all of the exhaust on the market will sound better than stock, some drone, some sound deep at idle, some are louder in cabin but in the end its not a GT3!
Fwiw this globally reknown US vendor and Porsche specialist I mentioned in my previous post would have much more to lose than to gain by telling me what he has about these systems. He is s straight shooter and it could be said he has no dog in the fight here. He stocks, sells and fits many of the well known systems (tubi inc) and has pretty well heard all there is to hear with products he doesnt stock due to the exposure he has in his operation. So it could be said by him informing me of what he has is definitely not in his best interest, but that's just the kind of guy he is and, there aren't too many of those about in this industry. So i appreciate having someone who can call something for what it is when asked even if it costs him a sale by doing so. If buyers of some of these systems that i've quoted are happy and feel they don't drone then i am extremely happy for them. Truly am.

PS. And on the topic of the EP he also told me that in his lengthy experience with the 997tt.1 car the EP product is as good as it gets in terms of reliability, fit and finish, manufacture, no drone, sound etc...and he no longer has direct supply for a profit margin. So again he calls it honestly.
