All-told, our exhaust system installed easily and quickly, even though the Schumacher headers we used for our big-block swap happened to be headers that TTI hadn't developed head pipes for yet. What this meant was that we had to fabricate our head-pipes, which was easy since TTI provided the flanges and plenty of pre-bent tubing. In all, we spent the better part of the day installing our exhaust with our car on the lift, but could have also done the job in the driveway on jack stands if necessary. We were very pleased with the fit and finish of TTI's products, and the Dynomax mufflers give our 383 a nice rumble at idle, but aren't too loud when we're cruising on the highway. Follow along and we'll show you how easy it is to install quality dual exhaust on your Mopar.
If you can find an exhaust...
If you can find an exhaust shop that will fabricate an H-pipe for you, they'll likely weld it in place, making future transmission service difficult. The TTI H-pipe is a slip-joint, held in place with a clamp, making removal easy if necessary.
Before installing the H-pipe,...
Before installing the H-pipe, be sure to slide the U-clamps over the forward end of the mufflers. The same goes for the tailpipes. The clamps should be tightened until snug, but don't final tighten the clamps until the exhaust is in place and properly aligned.
Because we're using the fairly...
Because we're using the fairly new Schumacher conversion "Tri-Y" big-block headers, our application was one of a few that TTI hadn't adapted their exhaust to yet. It was no problem, as they provided thick-flange and plenty of extra tubing with various bends so we could fabricate them ourselves.
Since our header collectors...
Since our header collectors are fairly close together, we trimmed about an inch from the smaller diameter side of our H-pipe to make it fit properly. A Sawz-All with a metal cutting blade works great for this. Or if you only have a hack saw....
With the clamps all snug,...
With the clamps all snug, the tailpipes lined up perfectly with the openings in the rear valance panel. We now directed our attention to assembling the head pipes.
The TTI flanges are the proper...
The TTI flanges are the proper diameter, and they're made from thick steel so they won't distort like the originals did. The chances that your local exhaust shop carries flanges like this are pretty slim.
We decided to also cut the...
We decided to also cut the end of the exhaust turn-down flush with the bottom of the rear valance panel for a cleaner look, so we marked the cut with masking tape and again used the Sawz-All to make the cut.
From underneath, the exhaust...
From underneath, the exhaust has plenty of clearance, and simply looks well-engineered. From the rear, our 383 rumbles nicely through its new dual exhaust, but isn't too loud when cruising on the highway. TTI exhaust is a great upgrade for any Mopar, and is easy to install in a weekend without the hassle of the local exhaust shop.
The tailpipes are a little...
The tailpipes are a little long so they can be cut to length for different exhaust tips. We used the turn-down style tips to mark and cut the pipes to the appropriate length. The tips are then held in place by the provided exhaust clamps.
