I have had trouble with my DiFillipo mufflers and cat. I will post some pictures up when I get on my home PC tonight. I have been running a 3.5" DiFillipo exhaust for over three years now. The mufflers are 304 grade stainless but the piping is 409 grade stainless. The dump comes HPC coated but the cat doesnt. I found the "high flow" DiFillipo cat too restricted so I got rid of it. Simon from Xtreme Ford Tuning flow benched alot of cats awhile back and found the DiFillipo cat to flow not much better than a stock T cat. I hope this helps out. Feel free to ask more questions. I do like the sound of the exhaust though.
Sad to hear mate but Im glad your geting a house. Its the best feeling in the world buying your first house so I hope you get what you want and hope you get to own a T in the near future. All the Best Judd.
wasnt there a shop in sydney or melbourne that build a citric acid T with lambo doors and big cooler sticking out the front. Does anyone know the car im talking about?
