Well long tubes are something I'm not going to get in to, they can also cost you some low end due to loss in back pressure, been there done that on other cars. They're not really all that bad to put on but at this point I don't really need them and wasn't wanting to go that far. I think I'm just gonna go with the manifolds for now and work on my suspension.
I found the dyno test btw from an old Ford Magazine from 97, it had all the popular bolt ons, they lost .7 foot pounds of torque at low end and gained 3 horse power at the top end. I don't think it's worth the trouble at this point so I'm not gonna bother with them for now. If I spray it and it doesn't do like it should then I'll probably throw them on.
Well thanks for the info guys, I got a 75MM Pro-M for pretty cheap the other day and put it on today, I guess I'll find out if they really do anything on a stock motor tonight at the track. The dyno sheet says 3 HP.....we'll see in my trap speeds.
Thanks again for the help.
