Exhausts (again)
Discussion
depends really on what you want & what your budget is - i had some cash available so i went with geary's exhaust & cat pipe and an ITG kit. the difference, both in noise & performance terms, is remarkable.
if budget is lower then there are cheaper exhausts knocking about, and the K&N / ducting is an excellent alternative.

You're muddling the manifold and exhaust. A 4-2-1 refers to a type of replacement manifold (the manifold sits between the catalyst/exhaust and the engine) that is much better quality than the standard fitment and allows the engine to breathe/expel gases much more easily.
Sports refers to a better flowing exhaust system, usually made of lighter/more durable materials and usually a lot smaller in the baffle department so louder and lighter.
Edited to add: A replacement manifold will increase power much more than a replacement exhaust, but an exhaust will be more noticable in terms of noise and looks!

Have a Janspeed 4-2-1 and single pipe exhaust (made for the Exige) fitted, sounds superb, a lot better than the 'wet farting' noises it was making prior to getting the new system.

Try www.ptp-ltd.co.uk, This company is part of MG Rover powertrain who make the K series enginee. Although offering their own products they also offer the Janspeed silencer and ITG induction kits, fantastic when installed

Wareing, you mix up two parts of the exhaust system. The JanSpeed silencer is available with an oval tailpipe and a twin pipe. In both cases, they are a new design which flows a bit better then the old (smaller pipes) design but only the silencer.
The 4-2-1 thingy is the exhaust manifold. The 4-2-1 you mention is the same as the one on the Exige. The advantage of this manifold is that is includes the flex-piece you'll need to remove the engine movement from the fixed muffler.
The disadvantage of this system is the lack of torque; it's way less then the EBD manifold.
The reason for this is found in the flex-piece. Due to this flex piece, the length of the pipes is not ideal.
The EBD is a similar system but doesn't include the flex piece. This can be solved by a flexpipe cat replacement or a flexicat race cat with flexpart. The total solution is more expensive but certainly deliveres more torque at lower revs.
Err.. yeah we sell this stuff..

How many different sports exausts are there - i heard an S2 one day thought it was a TVR till i looked the sound was immense and beautifull made beathoven sound like a toilet flush.
Any ideas what it might be i seen it on a laser blue S2 02 plate with momo steering wheel thats all i saw in Edinburgh if the owner would like to tell me
