TTI headers

Run what you already have, i'm sure your new engine sounds super scary to you and i am happy for you, but it's really not all that.......keep the step headers that you already have, they are more than adequate for that engine. Not even knowing the rest of the package i;m gonna guess that you will be a mid to maybe on a premium day low 7 second car that may just squeeze out 500 hp on the dyno.
