For those of you wanting to get a 3" DP, you might want to consider this mandrel bent DP at a great price!
At the tip of a couple other XR owners, I went ahead and bought a 3"
mandrel bent DP which was originally made for the 84 SVO. Got the
downpipe through Sacramento Mustang. Below is their on-line catalog
for the SVO. Go to the "Exhaust" section and look for
The price listed is $99, but I got the $10 "Web Coupon" special and got it for $89. Shipping was $12.17, which brought my grand total to $101.17.
The 3" DP is very nice - HIGH QUALITY! Had it installed on Saturday and it fit right in. It was a perfect fit on my 87 XR. I know that earlier XR's had tighter clearances around the transmission tunnel, so I can't say for certainty how it would fit an early XR. Seems like it would work fine and would only require a slight tweak - if any. Again, it fit my 87 with NO tweaks. It just bolted up and was welded to my existing 3" pipe.
Best of all, I was surprised at how much of a difference it made in
the way the car drives. I didn't expect much since I already had
a 3" DP (compression bent), 3" CAT, 3" into
Thought that I might not even notice a difference. Glad that I
was wrong! Engine definitely pulls stronger. I didn't run any
G-Tech tests since I wasn't even expecting a noticeable difference in performance.
Anyway, regardless of exact HP numbers, the engine definitely is happier
FYI... I measured the circumference of my old compression bent
3" DP at the bends. The circumference was about 0.9 inches less...which
equates to approximately a 0.3 inch
Thought some of you might be interested in this very nice
