Only thing I haven't done...

The only thing I havent done to my exhaust yet is the flex....

Roush Turbo kit

- 2.5 inch downpipe
- 2.5 inch ORP
- 3 inch catback.

When I was doing the rest of the exhaust I pulled the flex off, and it didn't look like it was creating THAT much of a bottleneck. I wasn't going to change it at all when I was NA, but now that Ive gone turbo its made me think abit.

Am I really loosing that much? HP? spool time? what are my gains?

- Basically I just want to know if its worth pulling it off and welding in a new 2.5 flex. Thanks

-- Cam
