    This was sold as an open box return item, however, whoever they got the parts from had pulled a fast one on the seller and swapped them out. Unknowingly, the item was listed as a higher model coilover but actually was the basic style. Once I brought this matter to the seller, they quickly and professionally came up with a fair path of recourse that both parties agreed on. They didn't have to do this but it just shows the quality of company you are dealing with. Would do business with again!

  • GREAT for CRX

    This exhaust is SLIGHTLY louder than stock at idle, if not audible at all. However it really opens up above 2k and 4-6k has a great tone. No can of bee’s here, just a great grumble all the way through. I have pictures of where to cut but this thing is worth it! HKS comes with all hardware and a sticker as well. Cheers.

    It doesn't get better for a nice, quiet, period correct exhaust for the CRX. LES-H05 is made for a Civic and does not fit the CRX without cutting and modifying.
