Making Lobster Back Piping

Finally got a chance to post up the pipework I done for dads GTR

Nice stitching!

Removed the factory pipe in the guard and ran all my own pipework and eliminated the join in the inner guard and made it 1 join up in the engine bay so no more pesky unaccessable hoses

Thought i might as well throw up some lobster backs ive done.

Did this 33 with all bends lobster backed, and everything in the engine bay lobster backed.. Even the straight sections were made from lobster back bits so the whole bay looked the same.

Cant remember the settings but i tig 1.6 tube on about 6-7 amps and use .9 filler wire from a mig roll. Not a fan of the 1.6 rods.

I also have some pics of a KE70 i did with a small intake and surge tank, and a NA-T supra i did.

Here are some pics of work I did for the Bright Print Group R32 GTR for WTAC 2013.

The main constraint was the ability to refit the full exhaust, so the dump position couldn't be changed (hence the tight 90deg after the muffler), it had to be a reasonable volume (stainless packed decent muffler to handle heat) and as much ground clearance as possible for trailer duties (this was 105mm off the ground, so it's above street legal).

3.5"dia 304SS to 3.5" straight through custom muffler with 100% stainless wool packing (for high temp) to a a painstakingly hand fabricated 3.5"dia > oval taper to the one-off oval 'boom tube' (over 4"dia capacity)

Looks different and sounds awesome.
