Great. My bonus rolls in about then and that’s paying for it! How loud is the valved exhaust compared to Porsche’s own? I’d quite like a little louder in the open mode! I’m guessing when coupled with the 200cell cats it’ll be a little louder regardless

Edit to add: what’s the difference between the X-pipe and the standard crossover version of the 200cell cats? It sounds like the X-pipe may be louder and/or sound different and have some extra potential with a remap (something I won’t get I don’t think).

I’m needing to get an exhaust sorted for my car, I currently have the gundo hack on standard boxes and I think it sounds superb, boxes are on there way out though.

I don’t want the car to be to noisey so I was wondering if anyone would comment on how loud the mild sport boxes and maybe 200 cell cats are over a gundo hack standard set up.

Haven't heard gundo hack in person on 996 so best I let the forum experts handle this one.

I would suggest to you the sports boxes for topgear are similar in volume to the gundo but have a more subtle tone to them . so if you want to recreate the volume of a gundo then just go with the sport boxes . the 200cell cats will inc the volume a bit more Imo not anti social loud . the 200 cell cats will give you a bigger BHP gain than just doing the sports boxes .though you will feel gains just doing the sports boxes as they are lighter and more free flowing than the OE Thumb

Magic thanks for the info, regarding the 200 cell cats, what increase in bhp are we talking wouldn it be noticeably different to the point it’s worth a little extra sound.

Mild sport sounds the way to go and hopefully should flow a bit better than standard and should be an improvement over what I have.

Power gains are +12-+15 BHP on the 200 cell cats.

That’s quite a gain for an NA car, do the rear boxes give an increase also or is this more for noise & less weight.

I’m now thinking it could be worth while doing the lot and see how it goes regarding noise.

I've gone from PSE boxes (which are the same as Gundo hacked boxes when the valves are open) to TG mild sports boxes and 200 cell cats.

The difference is night and day. The OEM PSE boxes had a much more refined sound to them, particularly at low revs. The TG set up is significantly louder from inside the cabin at lower revs, but the thing that really sells the TG set up to me is that at 3000RPM+ with your foot to the floor, the sound is just brilliant. It sounds like a LeMans protoype. Totally awesome. I'm not sure I've noticed the extra power, but I've certainly noticed the reduced weight. The new sound is so addictive, I'm finding myself just going for drives so I can hear it again.

Martin brilliant review and thanks very much, that was exactly what I was looking for. Are you using the standard exhaust manifold ?

Had the X-pipe fitted yesterday, my setup currently is therefore:

3.4 engine
Standard manifolds
200 cell x-pipe
Cargraphic silencers

The quality of the x-pipe is very good, Precision remarked on the welding, the fitting kit and gaskets were examined and filed straight in the bin however- Nyloc nuts which would not cope with the heat, oversized spring washers and cheap gaskets that would rust. I'd have preferred to have had no fitting kit, rather than this one.

With that said, now everything is fitted it is an utterly fantastic sound - slightly more mechanical at idle and lower revs but once past 4,000 rpm it's incredible, addictive, impossible to stop revving the car out to the redline whenever possible.

It also makes fantastic, angry barks as you heel and toe.

Very definitely one of the better things I've done to the car in terms of sheer enjoyment.

Good to hear you like the sound and quality of the TG mate as I know from your posts you are ultra observant and have high stds for your car. I will be interested to hear Alex's thoughts on the fitting kit and what you found. The reason I will be interested is to find out if they have changed supplier or components in the past couple of years, as when mine was fitted 5 years ago when I went back after 3.5 yrs to have a slight rework under warranty all the components came off very easily and looked in decent condition , so it will be interesting to have his input on it.

See topgear posts in this thead these are from Alex he is a Director at Topgear firstly he will not be happy that you have not recieved their normal very high level of service and I am sure will deal with that internally but most important he will get you the info on restock items . Try sending him a PM on here and /or call Topgear and ask to speak to Alex they will conect you directly to him if he's not away at a trade show etc. Hes a nice guy and very approachable so he wont mind if you contact him directly.
