These are longer in height but almost maintain the stock length. They are significantly thicker. The stillen ones are okay but yet they are still (somewhat restrictive). the first thing i noticed when i picked them up was they are very light (for a side intercooler) and the piping is very thin. But the are long and i saw a custom fab pipe set made for them. I would but them but i already have a R32 FMIC. I would have to make another set of pipes. But man is it tempting.
