This QUAD tip system is intended to fit the Roush Quad Tip or similar Rear Valance Modification. Unfortunately it is not designed to the GT350 valance.

Does the exhaust come catted or no cats at all? Also is it active exhaust?

Answers (1)

Corsa Performance 04 Apr 2024

This is a non-active Cat-Back. No valves or catalytic converters. To get active for a 2015-2017 you'll need wiring etc.

Is there a template available to cut away the stock rear diffuser when I install the Corsa Xtreme 3.0 Cat-Back Dual Tip 14335 on my 2015 Mustang GT? I do not have the Premium Package on my 2015 so the diffuser cut out is not wide enough for dual tips.......wonder if there is a template to help me know where to cut away to make room for the dual tips. Thanks. Peter Butala.

Will the twin tip SKU 14335 fit a 2015 Mustang GT without modifying the rear valence/diffuser? Or is the single tip SKU 14328 the better fitting product for a 2015 Mustang GT? And last question: is the twin tip and the single tip product identical except for the tips? Thank you. Peter Butala.

If your rear diffuser has the single tip outlet you diffuser would need modified to accept the dual tip set up. Mufflers are the same for both kits.
