Do it yourself, it takes maybe 2 hours at most, also it's just pipe don't overpay for a name. My Diamond Eye 4" works just fine and is quite a bit cheaper than MBRP.
Yep. They cannot require you to put a cat on a non cat vehicle. That is tampering with emissions. Call the AQMD and they will tell you like they told me. No cat if it didnt come with one. My 02 did not come with a meow.Go back to the shop that said they can do it, but only with a cat and tell them to look at your emission sticker. It clearly states Non-catalyst.
