Suzuki GT750 - Exhausts
I have bought a set of stainless steel higgspeed exhausts, with cost of chroming now-a-days, for me make more sense.
One well known chroming companies in Ashford, quoted £600 to finish off the polishing and re-chrome, where higgspeed produce a set of stainless pipes for about £600 inc VAT.

Machined up some stainless steel ends to go on a set of higgspeed, to allow the standard exhaust clamps to be used. Dave has welded them on the ends while making my pipes.

Exhausts fitted, polished up very nice.

Original Allspeed exhausts, bought these new about 1983 for £70, the down pipes are double skinned and do have a few minor creases on the inside of the bend, but nothing too bad. These expansion chambers have a really nice sound, and improved the performance quite a lot as my original pipes I had where completely clogged up. Gibson's as they are now, still produce this style of short can pipe.

Degreasing the exhaust, got rubber bungs that fitted in downpipe, poured gunk and shook it around to remove as much oil as possible, filled exhaust with a strong solution of caustic soda and left for about a week. Then the platers were happy strip the old chrome off and the old exhaust hangers have been removed.
|
Started by rubbing with 320 grit wet 'n' dry.
|
Welded up some new hangers purchased from Gibson's but they do require bending and welding to suit.
|
Roughly polished the exhausts before welding on the bracket.
|
Polished and ready for chroming, I was intending on getting it copper plated first and then re-polished before the chrome but have been told by one company the copper plating is likely to blister on an exhaust ?
|
I have cut the original end off and machined up a solid and as the original area was quite thin where the gasket seals where the inner skin didn't come up flush with the outer skin.
|
Made some titanium ends for the Allspeed exhausts.
|
Polished the 3 ends on the inside as well as the outside.
|
|
Before I found that gibson's sold the original hangers I made a set out of stainless steel, but after speaking to the chrome platers they warned me that chrome doesn't often stick too well on stainless.
