its a ebay kit... finiancial reasons made me go with that one. i didnt feel like spending a whole lot for that. the piping is solid. and the intercooler is decent. its mainly just to get everything fitted. im going to upgrade the intercooler later on, but i had this kit on my 240sx and it held up great. im going to tig weld all the fittings togther this weekend so there will hardly be any couplers
