J's Racing SUS304 60RS Exhaust

With exactly the same design as J's 60RS titanium exhaust, this exhaust is made from SUS304 stainless steel.
As per the titanium version, this exhaust is designed for higher horse power and increased throttle response. Diameter of the main pipe is 60mm (hence the name: 60RS), with an emphasis placed on performance at the mid and top end of the rev range.
The 60RS also weighs in at 8.8kg compared to the weight of the OEM exhaust at 13.8kg. A weight reduction of 5kgs!

Finish wise, the back box is polished up with a blue titanium like finish in some areas. I think it's a good idea to seal the back box with some metal sealent, given it's an 'applied' finish.
The exhaust system also comes with a detachable inner silencer, definitely useful for long journeys :)

So why did I choose the stainless steel version over titanium? Two reasons:

• Durability - Less prone to crack (taking into account thickness also) and stainless steel is much easier to weld than titanium
• Track noise limits - Stainless steel is denser than titanium, additionally the SUS304 version is thicker. The result should be a slightly quieter exhaust with a deeper pitch, which is sometimes perceived to be quieter than exhausts that produce high pitched sounds. This I can confirm and shall be noise testing my exhaust the next time I'm at a track.

The only negative is that it's heavier than the titanium version and in my opinion doesn't sound as good. However if I can't get on track with the titanium version it's a non-starter really.
