Hey all,

I'm still waiting on the release of MBRP's new 2.5" catback for my ST.
I just hope it won't be ridiculously priced!
Any hoo, here is what I plan on doing:

- MBRP 2.5" catback
- Cossie Header
- Cossie flex
- Steeda SRI
- BS delete




Would this be too "loud"??? I guess it's kinda hard to say since the exhaust isn't out yet.
I'm also guessing I would need an xcal2 to retune my ecu to remove the cel caused by the header and to take advantage of my new mods, right?
Is a high flow cat necessary?
TB?

Thanks for your input
