Redline brand ones, has a flexi joint has already failed from the looks of it, that caused about 13psi of the pressure in the pipe alone. Other reviews of them are they are S***. i got them in a rush as my up pipe had cracked. sucked as they also lost the subrua rumble They couldn't get it to produce over 200hp at the wheels and when it did go there it was bloody hot. All im after is something where i can push some more power for track use. the TD04 is great for boosting quickly bit over 5000rpm its all gone whihc is where you use the power on the track
Got the up pipe and headers now from v7 sti just need a turbo to make it all go.
