Hi, thought I'd post this up to let other members know of another options out there for exhausts. I recently bought a SMB turbo back exhaust. Havent fitted it yet though. It will be fitted next week some time. Once It's fitted up I'll post a vid of how it sounds. When it arrived I was pretty impressed with the quality of the welds and the overall look of the exhaust. It's australian made too. I will let you guys know if it's any good or if it's puss. I gotta feeling it's gonna be good judging by a few other members comments. It's a 4" off the turbo that half way down tapers to the 3.5" with a 5" cat. I won't be able to give you guys comparitive dyno's from this exhaust and any others (I don't have the funds, and I'm only upgrading from my stock exhaust), but once it's on I'll post a quick vid, and you can decide if it's good or sh*thouse. My mods at the moment are basically Nizpro Stage 1 plus. So Cooler, Injectors and Tune, which gets me about 290rwkw. I didn't change the cat from the start cause I knew I was going to eventually do the full exhaust system. About to go on is the process west race intake 6" k&n filter, battery relocation to the boot, process west fuel pump and surge tank, Nizpro plenum, and Nizpro ported turbo, flapper and 12 pound actuator, and the SMB Exhaust. So yeah, once It's all on, I'll post a vid, and post some dyno results. Just to stop a question which will probably come up, I didn't go for the full 4" system cause I won't be chasing numbers that will require it. Only really chasing between the 350-400rwkw mark. If anyone thinks I'm missing anything in my mods please feel free to jump in and say something, my car is used as a daily driver and will probably never see a race track. But might see a drag at some stage during it's life. Although not a big priority at this stage. So yeah, if anyone out there has a review of these exhausts you should post it here. So that any newcomers or people looking for a new exhaust can check it out. Just so the Mods know. No I don't work for SMB, I'm just a member who bought one, and I thought It would be good to have a post where us members could see what other peoples honest opinion of them were.
