High Flow Cats- X-pipe vs Separate Pipes in terms of noise?
Discussion
Hi all,
Regarding high flow cats on NA Porsches, I notice that for my 997.1 C2S there is a number of different options, seemingly split in pipework design.
One design is higher flowing cats on stock (separate) pipe designs, with each bank of 3 cylinders separate.
The other design of an X-pipe, where each bank is connected together in the middle
How do these two designs effect things in terms of sound? I'm not really interested in any power increases.
(I have the Gundo hack BTW)
Thanks in advance
Matt
