Hi,I expect my rebuilt engine back before xmas. I plan to replace the whole system. I think the Topgear option with the quieter box seems to be an ideal set up. What do others think? I pl an to replace the manifolds/headers at the same time. I have seen some on ebay for £160/£170. These seem cheap compared to Topgears @ £450. Anybody tried these and what was the quality like? Look forward to some input. Mike.

Had them on for 4 years & 40k miles. Nothing wtrong with them. Bit louder than stock too.

Did a couple of reviews here: http://911uk.com/viewtopic.php?t=107741

I recently went for the full Top Gear system from front to back with the mild sport boxes and regular 200 cell cat pipes (rather than x-pipe).
I went with the Top Gear headers purely for convenience and the expectation that they would fit with the rest of the Top Gear system.
It's still early days and I don't think the system has fully bedded in yet (probably only done c.600 miles). It is currently a little boomy at certain revs, but is generally unobtrusive at motorway speed, but definitely throatier under acceleration. It certainly sounds less "911" than previously, and doesn't have the turbine-like howl at the top of the rev range - not good or bad, just different !
I need to put more miles on it and drive in different situations, but for now the jury is out.
I can't knock the quality, price or fitment. It all went on very nicely and looks the part.

Some of the ebay ones have crude 3 into 1 joints that appear to have an overlay metal strip welded on. The better ones have cut and butt welded tubes. PPBB uses ebay ones on his 300k miler.

...having just spent a weekend removing my exhaust system using combination of blood,sweat , tears an angle grinder and reciprocating saw as a consequence of rust, rust and rust you have my deepest sympathy if you are taking this job on!

I am now replacing every nut and bolt from the manifold back with marine grade stainless steel which won't help me but will relieve the next owner of the misery I experienced Very Happy
