NEW Exhaust!!!

My Catera came OEM equipped with two mufflers located in front of the rear axle and a Resonator on the driver side behind the rear suspension.
After listening to a few clips where other owners have replaced the OEM Mufflers (under the rear seats) with straight pipes I decided it was too loud for me so the quest began to find a quieter sounding system with a deeper tone but louder then stock.
Thats when I found a few AUDIs running in the area with 3.0L V6 engines, 2 cherry bombs and OEM resonator... the sound was just perfect so I bought two flowtech mufflers off Ebay and paid a shop 100$ to install them. Total cost was around 160$.

But that was in 2007 and now its 2011 and finally the left bank broke the welds and as you can image it was time for an upgrade.
I chose to go with a less restrictive glasspack. Turns out Dynomax makes Thrush glass packs with perforated pipes internaly rather then the Louvered look on the Flowtechs. This not only reduces back pressure but it also increases the sound by a few dB.
The project took 2 weeks to research and plan and the result is 2 Dynomax Mufflers (glasspacks) and 1 2" x-pipe.

Here are some pictures.
OLD SYSTEM


OLD VS NEW


NEW System
X-Pipe after the two pipes come together just after the gearbox.
Those go into twin glass packs (24" long)
Mandrel bent pipes and welds for smooth flow.
Sound is deeper and more balanced, no more rumble.

not bad what was the final damage?

Total cost was 80$, and some 8hrs of my time from start to finish.

The two mufflers were 20$ each powdercoated factory red, and the xpipe was 40$ and its stainless steeel.

The rest of the system was cut and welded with a shitty MIG and a hack saw... not bad ehh?

Here is a vid I finally made but a new one will be made soon.

nice...im always up for budget builds :-)

Where did you find the 2"x-pipe? The only x-pipe I can find have a 2.25 inlet/outlet.
