Loads of mods on 996 and Gen 1 cars but what’s the best ‘bang for your buck’ on a Gen 2 car?

Elephant in the room (more like mouse) it’s too quiet, but what options are good value, Centre by-pass, PSE retrofit or new System? Any other way to improve the noise inside, engine mounts, induction, sound proofing?
Spend the money somewhere else like DSC Sport PASM, Wheel spacers, Short shift.

Or just enjoy its subtlety and go to the pub.

I'm in the same boat, looking to inject a bit of life into my 997.2 after 2.5 years of ownership. Was considering one or more of the following:

- exhaust upgrade
- short shift kit (GT3)
- suspension drop (mine is a high riding base model on passive dampers) and / or refresh

Will await responses to your original message from the more experienced 997ers on the forum!

Pretty much all the Gen 1 mods work on gen2...
Best bang for buck on the exhaust is a Gundo hack for around £250

Short shift kits for Gen 1&2 manuals are identical. Alex on the 996 section sells a modified eBay shifter for about £150 that’s is cheaper (and probably better made) than the Porsche gt3 version

Some rave about the dsc sport pasm upgrade but its not a cheap option, in fact it isn’t far off the price of a decent set of coil overs... a lot depends on if you think sport mode is too hard or not, most here do but personally I don’t so to me that’s not a mod worth paying for on a manual.

Solid/semi solid engine mounts are a cheap way to improve the fe

I originally thought I would do the Gundo mod but I’ve read a couple of times that it is less successful on the Gen 2. No idea if that’s right or even why that might be. I know the orientation of the pipes are different but the principal should be the same?
PSE was a must have on my list - so obviously I bought one without it Dont know

PSE by itself isn't that great tbh, but PSE with the centre silencer bypass Dance
I'd get the centre silencer bypass done first as it's pretty cheap and then go from there.

I have some 15mm spacers all round from my old car...

There is a lot of love for Top Gear Exhausts, but another option is the Tubi Style Exhaust which is what I have. Love it to bits as it gives me a quiet exhaust whilst in town and air cooled race car when appropriate, all controlled by my right foot. No drone either which is great on a long run at motorway speeds.

Exhaust is a must I think. Top Gear one with centre silencer delete pipe is good value & makes a big difference to sound. I have one in the for sale section on here if interested.
Only reason it’s for sale is I bought an ackrapovic off a member here.

I loved the short shift kit on my 997.2 (made the gearbox a real treat to use, like a rifle bolt) as well as the PSE. However, both were fitted by the previous owner, although both were genuine Porsche items. I would have sprung for the SSK but not sure I would have purchased PSE, might well have looked at other more exotic options if warranty wasn't an issue.

For me though, best investment in my 997.2 was tankfuls of V-Power and using it (did just over 30,000 miles in 2.5 years).

OP, if you really want some ideas you could always drop Phil 997 a PM, or scroll through a small sample of his mod threads.

I’ve just fitted the SSK on my 987 this afternoon, its the same part / fitting on a 997, takes about 90 min DIY and costs c£250.......well worth the money Thumb

You need to do the centre silencer bypass to hear the car. I did PSE and that. Mine is Sharkwerks, but others are available. I wouldn’t go with Top Gear due to the design.

This is a pretty good guide to tuning options on a 997.2;

https://www.sharkwerks.com/tuning-guides/997.2-carrera-s-4-4s-gts-2009-2012

I've got a PSE with a Hayward & Scott centre bypass on mine, luckily bought it with the mod already done.

I'm going to be doing my clutch later this year, considering a lightened flywheel for a bit more zing.

Best bang for your buck is probably to purchase lessons from a decent outfit such as CAT. That's an investment that will last a lifetime.
As for hardware, two suggestions:
1) take the car to Center Gravity and get them to "health check" it, with (most likely) a follow up visit to sort out the suspension
2) I had Ohlins road & track coilovers fitted for around £3.5k and I think they are excellent. Better in my opinion than any PASM setup.

You could of course combine the above.
Have fun modding!

Has anyone with a centre bypass experienced any MoT emissions test issues or ‘check engine’ warnings?

Centre bypass causes no mot issues . I think thats a good value place to start , some are happy with the sound others will want to go a bit further, but best to do a bit at a time. also while your doing that add BMC sports filters to your airbox .

You are right the gen2 sounds different to the gen1

If you was to improve handling which will increase the fun as much as adding power if not more then.

lowering springs, RSS engine mounts and spacers( I suggest RSS because I have tried all the other options except the 993rs mounts and RRS IS THE BEST by far for low NVH etc., easy to put back to stock when you sell and will make a noticeable difference to handling. worth considering getting centre gravity to do a full Geo at the same time for a perfect set up.

The DSC pasm upgrade module is a very nice item but quite expensive but it will allow you to use sport on uk roads without needing a private dentist .

if yours is manual the two options are the SSK with this whether you buy OE or aftermarket they have nylon bushes and are as sloppy as the standard shifter but with a shorter throw. there are several options with this you can ask Alex on here to fabricate you one with his metal bushes or look at the kit from function first in the USA . the second option is the OE GT3 shifter this is not starter than the standard shifter but has metal bushes and gives you the rifle action gear change . I had Alex's SSK with metal bushes originally but didn't like the Short shift even though if felt good with metal bushes so have now fitted a GT3 shifter and really like that for me personally as I prefer the longer throw but wanted the rifle action shift.

If your budget is bigger then consider a top end exhaust like Akrapovik or Cargraphic valved units with 200 cell cats but these are in excess of 5k.


I think 7.5k would get you a akrapovik or cargraphic exhaust, plus DSC module and lowering springs and spacers engine mounts and a GT3 shifter. this would certainly increase your grin but I do understand its also a lot of pub time and a holiday Grin Grin If your anywhere near Sunny Bournemouth I am happy to meet up and you can see what the various different bit I have mentioned do and sound like.

Mine is the Cargraphic exhaust but I also have all the other bits mentioned plus others like IPD throttle body , Chip Wizards remap, and various GT aerodynamic body parts .

hope some of those suggestions help Thumb Thumb

The other brands centre bypass’s are very similar to SharkWerks. I believe they even threatened legal action against Milltek.

I have the Haywood&Scott, which is an X crossover rather than

)( shape. Comes alive over 3500rpm but raspy rather than rumbly. I later added gundo which marginally improved things, then went for BMC cone air filters for more noise. The problem is the sound insulation means you can’t hear the engine inside the cabin. Sounds great for whoever is following though!

The best I have heard is from cgr automotive. Check their website.

I also echo CAT driver training. - great vfm to go faster.

Best cosmetic mod for £11 is to ditch the number plate plinth and get a stick-on plate.

1. +1 for Center Gravity. Not exactly a mod but they will advise and set up (with or without spacers) to how you want to drive it. When you have been you soon realise it's not as expensive as it might first appear. They will also recommend the DSC. I run in sport mode nearly all the time now it's that good but a lot of that was also down to the Center Gravity set up.

2. X-Pipe. I have the Topgear bypass system and it's a very good value mod. I wouldn't bother upgrading to PSE but rather would go full after market system for similar money and better sound. The PSE is OK but it's not great even with the bypass.

3. Front grilles. Ok wont make you faster but looks great if you go with something sat behind the bumper rather than clipped on like the Zunsports although both options could save big pennies down the road.

4. Sport Design steering wheel. Could even go 918 style but the sport design looks the nuts to me Razz

5. Extended Leather. Some big smile gains can be had there. Alcantara, contrast stitching, etc. There have been some lovely mods posted on these forums in the past that have got me into thinking I would rather go that route than spend loads for relatively small power gains.

6. Braided brake pipes. I wasn't convinced before I had them done but I am now.

7. Driver Training - CAT. Next on my list to do and will probably be my biggest win.

8. I am dreaming.......Sport Classic body kit....BIG $$$ even if going Design 911 but the 997 rocks a duck tail Wink

Have fun!!
