ETS Catback Exhaust ( Part Number: 400-28)
ETS non-resonated CBE 2 years ago
5out of 5stars

Very easy to install along withe the Grimmspeed OEM downpipe to 3in Cat Back Adapter. The quality of the product is very high. Sound and performance are good. With this version not have a resonator and be a 3inch exhaust, I really had hoped it would be louder and more aggressive (J-pipe is next). At highway speed there is no uncomfortable sounds or drone in the cabin. Overall, very happy with the product.

      A:  It will perform without any issues. The volume and tone of the exhaust will be the only difference.
