HKS Silent Hi-Power Modification

[Tim M]

Greetings!

We recently purchased a non-running Evo 5 project. We had hoped to use the existing exhaust (Fujitsubo), but corrosion has taken its toll.



We prefer a standard exhaust (non-angled) and quiet due to neighbors/laws.

The HKS Silent Hi Power is our top choice currently, but understand it is not a full 3 inch tip to tip. There is a neck down at some point - possibly at the resonator? We are adding a 3 inch elbow/down pipe and would like to maintain to the rear.

We've read where folks modify this section for full 3 inch - ask if folks could offer an image or instructions on how to accomplish.

Thanks!
