Is the 3076 externally the same size as what you've got? You might have a hard time fitting it in...
Was thinking I only needed to do injectors if I was going E85, and sticking will good old reliable 98 for now.
When Andrew was designing his stuff, I made him design it to bolt to the factory mount points so that if someone wanted your dump, and a Jap exhaust, it'd all fit. Funnily enough when I put out the EOI on the AM group buy, most people wanted mid pipes!
