Closer to pulling the trigger!

Part of me wants to go for Gerts HJS cats, a well known brand. But it means more hassle re: labour to remove/refit. Yet everyone appears to be happy with Powerspeed's unbranded job-lot-ordered-from-the-States cats (I asked them who the manufacturers their cats but they simply do not know...).

For anyone else reading with interest, worth noting the following all incl. prices from the original 911UK thread no longer applies:

adamw wrote:
Emailed Power-Speed today and spoke to Megan...Very helpful Thumb

Offer still stands:
£495 for the 200 cell cat replacement
£639 for the 200 cell cat replacement, exhaust bypass, tips polished

Megan has stated they ideally need 2 cars at a time for this offer to stand but providing this is the case this offer has no expiry for 911uk'ers (never say never but certainly not for the foreseeable future)


Their price is currently set to 600+VAT.

If/when I decide to go for it, and find time to get it done, I'll post back with some initial impressions Thumb.

Either route will be good. I can only speak from my experience. I am not sure if you say my post about me changing the spoilers on my car. While the car was in the garage I had them pull the silencers off and sent theme to Gert to have them modified. Gert organises the postage and all you have to do is package the component. He organises collection and ships back to you. It's hassle free.

On the basis my car is more of a weekend and occasional use i wanted to lift the sound a bit. It's definitely more full on at tick over but not that bad. With the sound deadening out you hear pops and burbels

In case helpful to anyone, here is the before/after of mine:
http://youtu.be/BCLu32VmmWo

I'm getting the rear mufflers made more aggressive (bypass pipes and removal of internal fluff) which I think is equivalent to Fister Stage III.

happy to post an update of how it sounds when I pick up the car on Saturday morning, if anyone is interested.

Very interested. I'm running Ceramic Coated Fister III's and the car is loud with pops and crackles on the overrun which I like. I've been thinking about 200 cell cats but unsure if it would be too loud, hence interested to hear your thoughts. Wink

Sure, will post a video when I get the car back...

Out of interest, what are the benefits of ceramic coating ? Wonder if I missed a trick and should have had this done? Question

Ceramic Coating reduces the radiated heat produced by the exhaust boxes. A lot of owners in the US run them without heat shields, however I chose to leave them in place as they were recently replaced for new.

Yes, I'm running without shields round the back boxes (Fister 2's - black ceramic coating) ... no problem at all.

I never got around to having the 200 cell cats installed, other stuff got in the way! what
However having heard a 993 with the Powerspeed cats today (thanks to fellow 993 owner, Sutton), coupled with the very helpful input in this thread, I'm going to go for it.

Anyone else interested before I call up Powerspeed to arrange a date? They may be able to do a deal if several of us commit to it.
Please post here to express an interest...

Thanks - I'll call up and get back to you. Expecting it to be around the figures at the top of this page anyway; anything better a bonus, anything more a disappointment.

Am I correct in thinking that i'd need to remove the cat(s) section, ship to them and they would fit the 200cell variants and ship back?

I know that's how it works with Gert/Carnewal, but with everyone on here that's gone with Powerspeed, they've driven there and waited whilst it's done. Clearly that would be quite the journey for you Laughing - so I'll ask if they do the shipping method when I call...

My thoughts too. Depending on price its a toss up between Gerts HJS Cats and these Powerspeed variants.

Sadly we didn't get enough numbers to secure a deal. Nevertheless, I finally had the 200 cell cats fitted this week.

To anyone on the fence: do it Very Happy.

Thank you to everyone's help, input and videos, in this thread. Most appreciated thumbsup.
