Looking to get a MAC Midlength/Y-Pipe combo. Coated, w/ emissions hookups. Just wondering what kind of rwhp gains I will see.

Everything is stock except tb bypass, CAI, and Hooker Catback.

Thanks.

You can see my sig with pretty much that exact setup. My dyno chart is there too. I have CAI, Jet-Hot coated MAC mids, Carsound cat, and Hooker catback. I also have the tb bypass but that's not really a hp adder, it just keeps hp from being lost when the engine is hot.

I am running through a single cat, and was a little rich on the dyno, so I'm easily capable of 295 rwhp going to an ORP and leaning it out a little.

Sweet! I'm only aiming for 300rwhp before I start saving for a new shortblock. So with my MAC y-pipe, I should be right around ~290rwhp? What other boltons should I get to get that extra ~10?

Thanks man!

BTW: Where does everyone get their Taylor OVC wires? I was looking at Thunder's OVC Kit that comes with Taylor wires. It's cut/fit though, is there a direct OVC setup I can buy? Link please.

 

Roller Rockers will push you to 300+

 

Thought about picking up some 1.6RR's/Springs but my motor has 145k. Safe choice? Are they something that last a while and could be swapped to a new set of heads without worry?
