Use a partial threaded bolt as opposed to a fully threaded bolt. This will give you a smooth shank under neath the hex head and keeps the plastic bushing from wearing prematurely.

I also ground down the thickness of the hex head in half for clearance, it was clicking on the clutch/brake housing mount.

Hope that helps you.

Decided to cost justify the welder a little more, ordered 3 more "U-bends" and fabricated the exhaust over the axle. Was able to re-use a little bit of the old tail pipe run as well, almost a necessity to fit the the tail pipe between outer body panel and leaf springs. Very pleased with how this all turned out.

A bonus as well, the exhaust drone was eliminated. Nice sounding exhaust now, very happy with the Magnaflows.

Refined horsepower with "raspy note" when you get on it.:twothumbs


First cut and weld of the "u-bend"


This is the same piece but opposite side, heading for the dump over the leaf spring.


Final joint and placement of exit.

As promised, now onto the results. Drove the car from St. Louis to Indianapolis for Mike Norris to perform the final tune and Dyno. Overall the car was set-up fairly close, just a tickle lean. Mike completed his adjustments prior to the first pull, made a few more adjustments and competed two more pulls.


Dyno shot. The cleanliness and organized shop says a lot about how Mike goes about his business. Highly recommended.

Not sure how else to post a video, so hit the link. Sorry!


Final numbers.

We have a small hesitation to remove from cruising speed/ acceleration, otherwise very impressed with the results.
