So I've been debating for a while whether to buy a divorced dual exhaust or duals with an h pipe. I'm going for Flowmaster 40s and I've heard both systems and i like them both. But I wanted to know from my sixxers out there if the h pipe gives any extra HP gains. I've read around that it does give gains and others say they don't and is not worth it. So if anyone can share their experiences and knowledge, I'd appreciate it so I can finally put duals on my baby!
