Anyone had a custom exhaust where they have run twin pipes from the cat . Eg twin 1.25 dia pipes. Or a set up close to the s2000 design except both pipes exit in the original exhaust location.
Just curious if the twin pipe cat back is quieter and still flows better than one big pipe ..........1.25 X2 =2.5
I have noticed alot of the newer cars such as bmw run twin smaller pipes. Was thinking they must be onto something
