I got all Helix exhaust on my 03 the only thing ive seen that was bad was when i pulled the motor and the uppipe off it looked liek the welds had broke on the up pipe, SO i drop it off at a shop had it re welded and went about my business. Bu tby far im happy with all there parts. You can get the uppipe,downpipe, midpipe and muffler combo for like 8something shipped from gruppe-s. Ive also head there coilover are to shappby and there injectors and turbo are pretty good as well. Im hopeing come spring to have the turbo injectors and coilovers. They also sell endlinks and sway bars as well. IMO pretty good company that trys to get it al to there customers
i believe they are made in korea, but they are definately quality if thats what you are worried about.
