full length headers question

Do any of you guys have full length headers and do they hit the floor of your cars and does it also need a Y pipe

Re: full length headers question

If they're thirdgen headers they won't hit the floor, and they'll only require a Y pipe somewhere if you're planning on running single exhaust.

If you mean do they hit the ground, then the answer is yes, every speed bump and wash out the header flanges either scrape or worse.

I don't know of any pre-built y-pipes designed for our cars with long tubes, you're on your own.

I think MAC used to make a system for Hooker Super Comps. Apart from that, anything with long tubes is going to be a custom job. If this is a street car, I'd stick with shortys.

It's a lot less hassle to use shortys.

Flowtechs aren't known for their outstanding quality. You'd be better off spending a little more money on something else.

Re: full length headers question

Hooker 2055s are a popular choice. They have the AIR tubes for emissions, and they include the Y pipe in the price, which most of the others don't.
