TTI ceramic coated headers with ThermalBarrier

For an idea of what this exhaust sounds like I've put three short videoclips with sound here; Under the hood (480Kb) Behind the tailpipes (447Kb) From the side (927Kb) Careful measurements were taken before the exhaust was fitted to the car The car is just done getting the TTI headers and exhaust and is on its way down the rack for me to take home While they had the car the seal around the dipstick tube going into the transmission went out and leaked 5 quarts of ATF+3 on the floor. Oops! The exhaust was complete with the Dynomax 17748 mufflers that have a very quiet tone but sound real throaty when you step on the gas The 'H' pipe is to balance the exhaust which quiets it down a bit. Supposedly it should go as close to the headers as possible but on this car behind the transmission crossmembers is the best place You can barely discern the bend in the headerpipe to allow room for the torsionbar to clear it The headers come down inside the torsionbars and the flanges land just behind the transmission oilpan There's still plenty of room to work on the transmission but the exhaust has to come off for the transmission to come out To clear the transmission crossmember the pipes have to go around it. The 'S' pipes from the flanges to the tail-end of the pipe are separate pieces Right behind the 'H' pipe are the mufflers. I didn't get any real good pictures of the neat bracket holding the mufflers up in rubber insulators The tailsection of the exhaustcomes out under the framerails with an elegant turndown which ends about 2 inches behind/below the bumper Almost a complete view of the exhaust system from behind the car The turndown is a separate piece that clamps and rivets onto the pipe. You can see part of the hanger mounted on the frame The hanger is a small bracket that bolts to the frame and contains a rubber insulator. A metal 'tab' on the pipe slides into the insulator to support the exhaust A view of the exhausthanger from the other side The headers needed ever so slight dimples to clear the torsionbars. It won't affect performance in an fairly stock engine. (driverside) This is the dimple in the header shown on the passenger side of the car A closeup of the collector bolted together with a thick gasket inbetween Where the pipes meet right behind the torsionbars there are clamps to keep it sealed There's also a clamp on the crossover pipe to keep it sealed and quiet Dynomax 17748 muffler give a nice deep throaty tone but yet very quiet The mufflers are clamped to the pipes on both sides to facilitate easy removal or replacement Another short of the headers coming out under the car The headers from the top on the passengerside. You can see the torsionbar going across the bottom of the headers In the top left is the mastercylinder, the center left shows the steeringshaft coupler Here you see the easier access to the sparkplugs. The mastercylinder is in the bottom right The tubes are out of focus but you can see them drop down behind the brakelines and steeringlink This is the previous exhaust that TTI cut out of my car, it's HiPo manifolds with 2.5" pipes all the way back with 'H' pipe and hemi mufflers A little closer view from the rear of the old exhaust Closer view from the front showing the HiPo manifolds These are the B body hipo manifolds that were on my car previously The hemi mufflers sound GREAT but since I got new ones I don't need these. I am saving them though. The exhaust tips are still on the old pipes, currently tucked away in the shop
