for s13:

I know this is a bold statement, and is as much speculation as saying that these products are crap, but I think SPL may be sourcing their products from motoria.
It would not be the first time either, seeing how the URAS rs exhaust system for s13 and s14 are made by motoria, the corksport exhaust for the fc3s is made by motoria, the corksport and JIC strut bars for the fc3s are made by motoria and an infinity of other cat-back systems are made by them.
Other things i've noticed:deluboz ruca=c-tune rucadeluboz traction rod=c-tune traction roddeluboz rear toe control rod=c-tune rear toe control roddeluboz subframe bushings=splparts bushings (although spl claims deluboz ripped them off)
I've also seen the following, although these I hope greddy has a patent of, and some company has the molds in taiwan or something.deluboz sr20 oil pan=greddy oil pandeluboz diff cover=greddy diff coverdeluboz sr20 intake manifold=greddy intake manifold
So let's not be so gullible to believe that our asian bretherens cannot produce these pieces w/a set of specifications given to them. The best way to prove all my assumptions as true or as lies would be to have items from both companies, and test density, mass, and other physical properties (maybe even look at the crystal structure of the metals) and compare similarities of both rods and spherical joints. Let's not forget SPL claims chromemolly construction, while ssa claims chrome coated steel. This would be the easiest way to see who's misinformed or lying.
Me, I've grown accustomed to companies outsourcing from South East Asia, and if a product looks the same to the last weld, well, chances are it is.
