At the 2012 SEMA Show, Heartthrob Sales Manager, Mike Forbes, met with us to go over the brand’s newest exhaust system. The exhaust system features their race-inspired muffler that deliver a high-flow rate without interior drone. And, that technology was used in their new 2011 F-150 Eco-Boost exhaust. The new 4” single kit boasts gains of +38 rwhp. The system is crafted from 409 stainless steel, is emission legal and won’t void your rig’s warranty.
