Fabricated exhuast system

Update Exhaust

While up on jacks, dinking around with the clutches, still dinking, I fabricated the exhaust system.
Using 3.5 in mandrel J bends and a couple of 45 bends and Dynomax race bullets, I put this together.

Intent was to get maximize ground clearance, and keeping the pipes clear of the trans to allow easy access to the shifter, clutch, drive shaft etc.

The race bullets are a little sporty, I welded flanges in the back, so I can pop on some chamber mufflers if the hood gets concerned.

Once all fabbed up, mocked up, I tried to come up with a way so they wouldn’t look like crap up next to my nice ceramic headers…So I shot them with VHT aluminum caliper paint, about 3 coats, then came back with Krylon Alum paint..the Krylon is not temp paint, but the caliper paint is enough to protect it.

I’ve run it in the garage up to temps, revving on the motor and so far its looking good.

Re: Fabricated exhuast system

Header evac system might not play well with chambered mufflers.

Looks good tho!

I gave up on big exhaust. I just do 2.5inch mandrel bent and install cutouts.

Nice. Let us know how the paint combo lasts over time. I can't see in the photos where your WBO2 sensor is located.

Not gonna use one, old fashioned read the plugs. Dennis and I chatted this up a while ago, and he doesn't use one either...been reading up on em, and not sure its worth the squeeze.

Thanks, I gave up on big exhaust. I just do 2.5inch mandrel bent and install cutouts.

I ran the header evacs and chambered on the SB set up for a couple years, a lot of hooey about build up and smoke, those 2.5 in Flowmasters are still hanging in the rafters for another build, and just as clear as a bell. I guess if a header sucking that much oil through the vents, you got bigger problems?


Never will go over the axle, the rear is narrowed and with the current shock set up, its tight..even with 2.5s so not worried about being too big.

Cool, I've always heard otherwise, which is unfortunate as it seems like a slick setup.
I've seen your build on the 460 forums, great stuff. love the car.

Re: Fabricated exhuast system

Good Job Chris. I can guaranty it will be loud on the street, although I have a friend who lives in a large city and seems to get away with it without the tailpipes. He has been doing it for years but still cringes when he sees the po po.

Hoping that the downward facing 3 bolt flange doesn't present a speed bump hazard.

No kidding Dennis, amazes how I do stuff, based on what Ive done/seen for years, and then after its all welded up ....DOH...notice I shifted it to the rear, where I actually have the most room LOL!


right now the pan is the low point, not a good thing..but I think I have 6 inches at current ride height.
