can I change the system on my own or is it worth going to a garage to do it as I don't have any way of jacking the car up other than on the standard jack.

Suggestion

I thought for ages about changing my system but I think the OEM sounds and performs best where as others may sound good but I'm not sure about there performance anyone I had seen on dyno results looked to have lost some low end torque compared to stock.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi guys what exhausts do you have? Ive seen a few that i'd like to hear in person but I don't know anybody that has them. So far the ones ive seen are; Dansk sport/supersport (heard supersport is too loud but would need to hear this myself?) DesignTek sport supremacy PSE (quite a bit more expensive than the other 2 but is it better) I would appritiate anyones opinions on any of these 3. Cheers Chris P.S. I would settle for a GT3 like exhaust note[ ]

POST 2Original post

Hey Chris, I have a PSE fitted. Love the growl and its been modded so I can have it quiet as well. The loudness as not speed dependent any more.

POST 3Original post

I like stock modded too. I think its the best exhaust apart from the fact its not stainless.

POST 4Original post

The standard exhaust is stainless, but where it is welded at the seams it reduces the stainless properties, and they go crusty.

POST 5Original post

In that case what do the blast up like with glass beads? Anyone?

POST 6Original post

The originals on my C2 cleaned up fairly well with shot blasting. No pics, I'm afraid - I gave them to my neice's boyfriend.

POST 7Original post

I've got the PSE and it sounds great. But no way would I pay £4k to put one on the other car. I'd consider FVD and Manthey.

POST 8Original post

I going to do mine soon thanks Richard,(plenty of rainy days lately LOL) Sorry all for off topic and apologies to Chriscoates81. I thought for ages about changing my system but I think the OEM sounds and performs best where as others may sound good but I'm not sure about there performance anyone I had seen on dyno results looked to have lost some low end torque compared to stock. A bit of back pressure is a good thing is it not ?. Regards.

POST 10 / ORIGINAL POSTEROriginal post

Also is it worth changing the headers or just the silencers? can I change the system on my own or is it worth going to a garage to do it as I don't have any way of jacking the car up other than on the standard jack. Cheers guys oh and also the guy above me, what where you saying no too?

POST 12 / ORIGINAL POSTEROriginal post

So do you guys think a 12 year old exhaust can be modded with a bypass pipe without it falling apart? And whats a realistic guess for manhours to remove and weld? Cheers Chris

POST 13Original post

Chris, Roy had his done and it sounds awesome. Check out this thread. You may have already read it! http://www.porscheclubgbforum.com/tm.asp?m=657829&mpage=1&key=exhaust&#659916

POST 15Original post

[ ] I've just read Roy's post and this seems like a good idea, does anyone know how much it increases the sound level as I would need to keep below the 105 dB limit for trackdays. Many thanks

POST 16 / ORIGINAL POSTEROriginal post

I also read about sombody removing some harmonic thing from the filter.

POST 17 / ORIGINAL POSTEROriginal post

And while I remember, are any of you guys going to RPM specialists in knaresbourgh tomorrow?
