Big thanks to Svxfiles for his help and Green_eyed_lady for her hospitality. Spent the weekend with Tom, installing the parts for my new exhaust system.
All that is left from my old exhaust are the Magnaflow muffler and tips. My new set-up was centered around a 2-into-1 high-flow Magnaflow cat (part # 94037) I purchased from performancepeddler.com for $60.77 shipped to my door!
I'll post pics of the final set-up by next Saturday, as I have everything held together by clamps at this point (will have it welded next Saturday).
My new exhaust lay-out is as follows:
1. From stock headers back to the pair of front O2 sensors is the stock exhaust pipe (removed heat shields - will eventually wrap in some insulating exhaust wrap from Summit).
2. Directly behind the two O2 sensors, is 2" O.D. (1 7/8" I.D.) pipe that goes straight back past the trans and then makes a bend into the area where the stock secondary cat resides.
3. Two pipes go into the Magnaflow 2-into-1 high-flow cat (2" dual inlets, 2.5" single outlet). This particular high-flow cat comes with a bung to accept the OBDII third O2 sensor.
4. 2.5" pipe then goes back to the Magnaflow muffler and tips.
The current sound is great but a bit raspy due to a few small exhaust leaks. Around 2000-2500 rpms is does get a little blarish, but within a week, when I get the pipes welded, I also have a high flow 2.5" resonator installed as well.(after which I'll take the final pics!)
