Suggestion
I could get some used OEM mufflers on EBAY but compared to going that route the Top Gear / Powerflow mufflers seem to be a bargain.

Everyone,
I came across an opportunity to purchase a Powerflow Exhaust for my 2001 996 - don't know anything about this company since I know Fabspeed, Billy Boat, etc are more common. Does anyone know anything about Powerflow Exhaust and their applicability to the 996 and/or reputation and performance gains?
Thanks,
Matt
Best thing about the exhaust is its fairly easy to take off and on, if the price is right give it a try?
When you say "exhaust" and we talking mufflers, cats, headers or all/some of those?
If you purchase and install, please post your impressions. These are incredibly affordable. I was planning to send my OEM mufflers to Fister, but mine are starting to show a split along the bottom seam and don't think they would last in the long run. I could get some used OEM mufflers on EBAY but compared to going that route the Top Gear / Powerflow mufflers seem to be a bargain. They get pretty good reviews on some of the British forums, but for some reason I have found very few reviews of them here in the US. I'll be curious to get your impressions.
Hey folks - they are fairly well regarded here in the UK and the customer service seems to go above and beyond that of some of their competitors -

I bought the Topgear 200 cell and mild sport early this year. Love them! Good price and good quality. I went with a group purchase on 911uk and saved another 10%. Sound is very nice with good tone and just-right loud, absent any droning. I’m very tempted to give the manifolds a shot next. Very strong customer service and very good rep in 911 community.
Thanks for the inside baseball on the powerflow/topgear exhaust. As for note, this is a daily driver in suburbua and professional settings. Not too loud/annoying? Any performance gains to speak off (hp/torque)?
I had the Helmholtz resonator delete with stock filtration and standard ECU before adding the Topgear bits. Sweet sound improvement over stock. Maybe a little hp and torque add. They’re just loud/noticeable enough to make the professional suburbanites jealous. When I put the foot down, above 4,000 rpm I swear angels are singing, but not certain ‘cuz I only hear flat six opera.
