Hi fellow ISF owners. Newbie yep! Have been watching this forum for quite a while getting info on the PPE headers and hi flow CATs. Have had my ISF for a bit over a year and had the Lexus sport pack installed i.e cold air intake, port and polished heads and sports exhaust. While I love the sound of the mods I personally haven't been impressed with the performance increase hence wanting to finish the job with headers. I have had sooooo many comments on how good the vehicle sounds now but that this is not the reason for wanting the headers. Purely performance. Cat back to my mind is sound only but not the full deal , the performance issue is to let the engine breath as best as possible. Elgin. Thanks for your posts. Makes me more confident that there is a reasonably cheap solution to this issue. I will give your boys a ring and drop your name like you suggested.
I love the ISF but I'm sure this engine has sooo much more potential. To me it's a stealth bomber. No one really knows WTF it is. A surprise package that's for sure to the unsuspecting driver of a performance vehicle.
Would love to catch up with the Brissy boys one day and check notes. Not too many of you boys around. I'll see an ISF every two months if lucky. A lot more exclusive that the common BMW's or AMG's. Keep trucking boys. Hope to hear from you.
