Any Zetec exhaust will fit the SPI. I'd recommend the MBRP, personally, as they're familiar with the SPI (they did my old car) and I know their 2.25" system mates up perfectly with the stock system. Your tweaks, depending on the overall length of the new stuff vs. the stock system, should be minimal at best.
