GMT-400 My Exhaust - MagnaFlow - PIC HEAVY

[nubuilder]

All this was actually done in January 2010. Just thought I'd add it to the site .

Fully stainless steel from the headers back. All 2.5". No X or H pipe.

Parts list:
2x MagnaFlow 99006HM Universal Catalytic Converter (Non CARB compliant) = $82.25 ea.
2x MagnaFlow 11226 Satin Stainless Steel 2.5" Oval Muffler ============ $68.03 ea.
2x MagnaFlow 35143 Stainless Steel 2.5" Exhaust Tip ================ $34.06 ea.
1x MagnaFlow 15042 Stainless Steel Exhaust Tail Pipe (driver side) ======= $50.01
1x MagnaFlow 15043 Stainless Steel Exhaust Tail Pipe (passenger side) ==== $50.01
2x Vibrant 1482S 3 Blt Ss Exhaust Flg 2.5" ======================== $20.40 ea.
2x Vibrant 1462 3 Bolt Gasket 2.5" ============================= $8.40 ea.
2x Vibrant 1194A Standard Oxygen Sensor Bung =================== $5.40 ea.
1x 14ft 10in 2.5" T304 Stainless Steel Pipe ======================= $168.00 (approx.)

Total (without installation) ================================= $705.10

I just thought this was cool.

Well, after 3 and 1/2 days of not having my truck, I finally got it back. The original estimate was to have it done in 1 day...oh well.

14 hours of labor were spent on my truck, but they guy stuck to his quoted price of $400 (the guy said he'd never quote a job like this again).
Ended up adding to the bill 8 3-bolt stainless steel flanges, 1 O2 bung, and miscellaneous hangers/isolators.
Total installation bill: $582.36
Plus I owe a friend for 5x 45 degree bends and 4x 90 degree bends at $8 each: $72
And I have about 2 1/2 feet of T304 tubing left. Pretty d*** close.

The reasoning behind 8 3-bolt flanges is that the guy recommended it so that the system could be taken out in the future.
There are 3 sections: headers to behind cats; after the cats (intermediate pipe) to after the mufflers; tailpipes.

Well, the two MagnaFlow pre-bent tailpipes did not fit properly. They had to be cut, twisted, and/or bends added (any combination of these).

I am very happy with how things turned out.
It looks and sounds amazing.
It is actually pretty quiet in the cab.

I took a few pictures of the installation with the truck up on the hoist and tried to take a video of the whole thing.
They're not the greatest (really bad lighting; shadows).

How many cats come stock on these trucks? Do you only need 2 to make it legal?

I've been thinking of getting everything plus headers before I install so that I can save a bit of money.

You could couldn't you? You'd just need CARB compliant cats wouldn't you?

I believe the 5.7L came with 2 cats. I think the 5.0L came with 1, but I've never seen one.

Yes, definitely get the headers in first. That way you'll have your starting point for the rest of the system. With the Tri-Y headers, you can't use direct bolt-on parts that you could use with shorty headers.

Nice!

Thanks!


I should really takes some new pics and a new video, but I'm afraid of what the pipes will look like after 2yrs.

Unfortunately yes . This is why I am no longer driving it in the winter. The salt get everywhere!
