Well I got the car back after some open engine surgery to replace a damaged valve lifter which entailed a lot of the "while I'm in here" work inc the dreaded IMS. My, perfect, IMS is now a paperweight on my desk.
One of the jobs was to change the exhaust as the original one was badly corroded. Went for a full system from Topgear: new manifolds, 200 CELL sports cats, mild sports silencers. Overall my indie in Cork who was doing the job was very impressed with the fit and finish. I was nicely impressed with the sounds, it can be a bit rorty at low revs so, just keep em high. Service from Topgear was flawless.
It's quiet when you want but when you open it up it's nice and loud but not offensive.
anyway, here's a wee track with some noises while parked up.
edit - oops, I'll need to work out how to upload an mp3 file, doesn't seem to like it!

Well a year after receiving my sport sound boxes I finally got them fitted yesterday.

For the last 3 year since buying the car, I thought it was very quiet running the quiet Dansk boxes that it came with.

After the indie installed them he mentioned that the car already had Top Gear 100 cell cats. So I now have original manifolds / TG 100 cell cats / TG Sport Sound boxes. The result.
When you’re on a constant throttle it’s pretty much the same as it was, no drone to speak of.

Small increase in throttle pressure = small noise
Medium increase in throttle pressure = Medium noise
Bury it in the carpet = race car

Its a toy, rather than a daily and I absolutely love it. So much more character.

My car has Top Gear cats fitted (by previous owner).

I keep getting an engine check light coming on with the diagnostic code P2098 (post catalyst fuel trim system too lean bank 2).

My local indie thinks the cats have extenders to trick the O2 sensor readings and this is triggering the fault message.

Has anyone else had this problem with these exhausts/cats? Or know how to sort it?

Hi,

The 200 cells should rarely if ever trigger CEL. As we like to say cats are usually the symptoms of a problem elsewhere. First of all are the sensors in good condition?

I had the same issue, spent a couple of grand trying to sort it thinking it couldn’t be the exhaust. Turned out to be a leaky gasket on the rear exhaust manifold.

Alex,
I would be interested in valved boxes and possibly 200 cell cats when the next group buy is available.

This weekend I suffered the dreaded although not surprising broken flexi on my Dansk boxes - pile of crap they are and hopefully everyone is now well aware of that!

The top gear boxes sound like a great product and I’m ready to push the button.

Question is, is the group buy still open or do they offer a forum discount?

No group buy currently but there is a Forum discount of 10% (see third post down here: http://911uk.com/viewtopic.php?t=126107&postdays=0&postorder=asc&start=340&sid=b43c539dfa9ac695dff6bcb2e89890ab).

I have a full TG system and it’s excellent. Give them a call. thumbsup

Thanks FRZ

Question now is, will the usual ‘mission creep’ set in and will I feel the need to replace the manifolds, hmmmm

I recently added the switchable Top Gear boxes; they're epic.

The conventional wisdom seems to be never touch your manifolds, unless someone already replaced them or they're blowing.
