Hello 1Addicts!
I'd like to introduce the new RPI Quad Exhaust System for the 135i. This system will include a dual to single back to dual setup for the optimal gain on the powerband. The full system retails for $2,995 but for the first 5 buyers, we will do an introductory price of $2,685 shipped in the continental US! We can also do install for local customers and offer OEM replacement diffuser for $120 shipped.
*UPDATE* Every order will now include RPI scoop free of charge. To those that have already ordered, I will go ahead and ship those to you separately.
