HSTuners - mufflertech.com catbacks

I was orignially going to go for a Tsudo slant tip cat back for my civic, then as I was browsing ebay I noticed these full catback systems from this wholesale company (www.mufflertech.com). they sell full, 2.5'', stainless catback systems for like $200-250 plus shipping. all of their ebay feedback is positive and people really seem to love them. if the piping and muffler is all stainless and if they offer lifetime replacement or repair, I wonder why I shouldnt go with them?

anyone dealt with them, heard about em? Let me know ;)
