Exhaust System Identification

[SamL7]

Hi All

A little help please :-)

Can someone help me identify this exhaust system? I am under the impression it's for the K-Series, possibly VHPD or VHPD race.  The short collector doesn't look like other photos I have seen for the VHPD system.

[SLR No.77]

The primaries and silencer look very much like a SLR VHPD system but as you say the collector doesn't. The VHPD system for the road has a separate cat as standard which doubles as the collector, the cat is definitely longer than the short collector in the photo. Do you have any dimensions?

Stu.

Looks like a 4-1 race exhaust like mine. I'll try to find a picture.

Thanks Stu & Tom.  Will get some dimensions!

It's definitely the 4-1 race exhaust. The SLR/ VHPD is a 4-2-1 system, with a shorter inlet pipe into the silencer to accommodate the longer 4-2-1 collector. The primaries for cylinders 2&3 are a common piece, and 1 & 4 separate. Apparently this system is better at high engine speeds, and the 4-2-1 SLR system producing more torque in the mid range.

That certainly looks like it Tom!  Thank you!  Looks great on the car.
