thats a massive generalisation. Fitting an exhaust is not a hard thing to do. thats not the problem. the problem is that the exhaust is too big for the space that toyota made for the exhaust. it was designed for the standard exhaust, not a CES exhaust. I can honestly say that i think the exhaust is awesome, but i cant say its perfect. everything has its faults. Its not a generalisation its based on the evidence in the thread. The guys having problems are not in Queensland. I will stand corrected if they drove up here and had it fitted. But it looks to be mainly fitting issues these guys have had. Azza had an internal failure which seems to be different to the other problems. When the system was on my car I didnt see any space issues. The only issue I had with my CES system was the family didnt like the noise level. I loved it around town but on a highway trip it was a bit noisy for extended traveling. My XR6 Turbo wont be getting a CES system not because I dont like the quality but because the thing is fast enough as it is.
