A bit big yes, especially if it is just the 175 and doesn't have extractors.
Go twin 2 1/4".
The system I recommend is the 2 1/4" twin into 3" single, $495 shipped. Add about $30 or $40 to fit. Unfortunately, this system is only available for sedans.
To keep your exhaust velocity it really needs to go into a single 3" behind the mufflers, the sedan system can be modified to fit, it needs two short sections welded in before the front mufflers.
