X-Force Twin 2.5" Cat-Back Exhaust | 2007-2013 Lexus IS F (ES-LISF-CBS)

Like others have said this is perfect for the Isf it truly opens up the sound in a good way

The stock IS-F exhaust is not very good if your looking for the good option for the price then X-Force is a the way to go. Make sure you have the right O2 sensor socket. The fitment is accurate no need to modify anything. If your looking for a loud exhaust then you will have to delete the mufflers.

This exhaust sounds perfect. They aren't too loud but they aren't as quiet as the stock ones either. There is a bit of drone from 1.8k to 2k revs but isn't too overbearing. And on highway speeds, it doesn't drone much at all. Very happy with Ma Performances service as well.

Perfect fitment. Very nice sound.

This exhaust is the one you want if you have an ISF.
Easily improves exhaust sound without being too over bearing. The perfect noise level for being a v8.
Cant fight the great price either as there are not to many lower price options out there for this car.

Grab one if you have an isf asap. Ps MAPerformance prices matches ;)
