The Magnaflow X pipe is cheaper than the heartthrob and is advertised as SS. Doesn't say what grade though. There are a few X pipes on Ebay that look exactly like the MF true X pipe for less than $40. One is 409SS and is around $35. That's the one i'd get if I had to do it over. I have the MF true X. If you have the L99, you'll have to weld in some tubing as well and if a muffler shop does it, it will most likely be aluminized.
