Exhaust,intake,throttle body spacer

[Hunner]

I have looked at a lot of high dollar bolton stuff online. In the process of deciding and not having picked out a muff, I just took off the stock one, used part of a 180 mandral formed piece and poof. Straight back turn down about the same heighth as it was on the other side protected by the spring shackle.
Idles with just a little Hum, not loud in cabin at 65, a little Hum at 65 pulling boat, (it is a Hummer) but stomp it and it talks! Seat of pants dyno says, oh yeah, if a Magna flow is low resistance go figure no muff resistance. Figure HP gains with any muff and then no muff. Dyno results in about a week. Kept Cat and res which must be like an old Cherry Bomb glass pack to be this quite with no muff.
Im working "with" a local manufacturer of throttle bodies and air intakes. I just happened to be the first H3 to drop by. Tuesday we are going to try a Colorado throttle body and make any mods on the CNC. Then fab up an air intake. Dyno for results of HP, torque and then do some MPG. Results on a Colorado were 10HP and 6 FTLBS 1 to two MPG. We will see. Pics to follow also.
I tried to be brief! Now if I could put a fuel cell in that hole for more range........
