Anybody heard of a SI manifold?
 

As the title says, ive got this manifold and the only markin I can find is a little emblem with si on it so I guess that is the make/brand. Anybody heard or have these? Thanks

ive done a bit of googling regarding gt spec headesr and found most are made in a factory in taiwan ssi.

Hmmm I did spend about 5-10mins grooglin, n couldnt find much! I dont like the idea of Taiwanese knock ups, but it does look/feel good although a lil agedu its slip/joint fitment, and by what I can make out its titanium.
Just to note its not ssi, just si with a fancy swoosh around it, I'll get a decent picture in the mornin n see if it makes any more sense lol

not sayin theyr not good mate,ive never used them,just looked into gettin a set.

Just looked abit closer, thats definitely them! Haha gota love their translation on that link! Well theyve been on the car for about 4 years so I guess thats something to be said for them! The previous owner has spent abit of money on it and from the very short play ive had in it it pulls very nicely, so that cant be that bad? Just thought I might of pulled up more user reviewage lol

Also theres not a clear price on that site, you figured out how much these are?!

im not 100% but according to others,r.c.m/lateral/clinic ect ect are all imported from the same factory,there mite be different specs but pretty sure thats were theyr from.they can crack with heavy use of a/l l/c.

i dont think you can just order one set,it looks more like trade only.

Ye ive heard similar things about other thai/china products, most of it bad like 'oh it will crack in 2 weeks' n 'its just dead weight in comparison to a top name' but maybe... just maybe... ive got on of the few good ones... haha
