Upgrading your exhaust system is an important mod everyone should do. and as we all know it can be a highly expensive one also. with the higher quality cat-backs ranging $400 and up. Not to mention alot of people dont like the cheaper cat-back systems out there, or the lack of custom shops in certain areas to have your own made with clean mandrel bends.
So heres a site ive come across that offers pre bent piping with mandrel bends. its available in 2.5" or 3". and available with a magnaflow muffler and tip or just the pre bent piping so that you can use any muffler and tip of your choice. all at very reasonable prices.
hope this helps some people
