Anybody need any weeds burned?

I can handle it if you need to get rid of the pesky trackside weeds.


Got my car back from the chassis shop. Whole list of stuff done. Headers included. I would have liked them under the car, but no way the 4.5" collectors would fit without dropping the ground clearance to about 1.5". Like this I have 3.5" and it will help get the alky fumes out from under it.

More pics to come.

Gonna be hard to keep the car clean. Especially in the dirt or gravel. Before you get them coated you might want to see if he can turn them out through the fenders. On another note it should deaden the sound very well though. JMO, Don't take it the wrong way, just that I have seen first hand how clean you kept the dragster and I don't think your gonna like the dirt and dust on and under the car.

Travis,

We considered turning and goign through the fender, but the entire factory A pillar is behind that little bit of fender. A lot of hassle and might weaken the car. I may see if I can find some 90° turnouts. Cut the collector 2-3" up and weld the 90°. Problem is finding a 4.5 90° with a tight radius. Lot's of 4 and then 5". All the 4.5" 90's I have found so far have like and 8" radius and are too big. I realize it will kick up dust, but luckily 90% of my racing is at my home track which has the entire pits paved.

any semi truck shop should be able to get it for you

I don't think I've ever seen a pipe that dia with less than a 8" radius. 4.5" is not a very common deal at all, once you hit 4" the diameters tend to go in whole inches. I waited for over 3 months for a common 4" exhaust pipe for my sprayer. You might try to find a pipefitter that works with stainless steel, sometimes they have some off the wall stuff with small radius bends.

I definitly appreciate the offer, I do all of my own weed burning. LOL.

David,
I would highly recommend that you put some turnouts or back a little on it. If you can find a 5" turnout with the bend radius that you want, you could cut a section out of it and weld it back together. The circumference of the 5" tubing would be (3.14x5.0") or 15.7" and what you want is 4.5" diameter so that would be (3.14x4.5") or 14.13", so you would need to cut a sliver of about 1.5" and then weld the seam back up. You could use some large hose clamps to pull it the seam back together and keep it round.

Try these folks.

Thanks guys.

I talked with Tim Murphy at the The Fab Shop Headers today.

Tim is going to make me a set of slip on turnouts. I'll cut the collector a little shorter and hopefully the low point will still be around 3.5"

Dave,

Just an idea, See if Tim can do a round 4.5" to oval 4.5 outlet. This would probably give you a little more ground clearance judging by your pictures Dave. Everything looks good on the car including the headers, Just don't see you being happy with the dust and dirt blowing all over your nice car.

You went to the right guy. Tim is making my zoomies at some point in time. His shop is just a short hop and skip from Andy's

A big X2 on Tim, I bought my header kit from him, and it is top notch stuff. He gave me several tips along the way to get them together. Real nice guy and a great fabricator.

Well, it was worth a shot, but it's a no go. Not going to be able to use the turnouts. For a 4.5 diameter, the shortest overall length possible makes the turnout 9" tall overall. I used an old collector as a dummy to hack up. I had to cut away most of it for the turnout to fit. I think almost no collector would hurt the power. Even then, I only had 2" ground clearance and I think it would burn the paint on the fender.

I'll just live with it. My dragster had downswepts that pointed at the intersection of ground/tire and it wasn't too bad. Thankfully, my home track has totally paved pits.

Napa can get a 4.5 90* a few weeks back my buddy aka 557 mazda was putting turnouts on his he used one off a big truck cut it in half in the middle of the 90 Napa was the only place around here that could get them.
