I purchased my piping from mandrel-bends, good to deal with plus they ship to Canada via USPS.
I used a Vibrant ultra quiet resonator. It's built with a true straight through core. It also eliminates any drone or rasp and is very well made.

Couple of added thoughts here:
As noted KEEP the stock FRONT Y-pipe which merges two into one.
Cut AFTER the two pipes merge into one leaving apx 1" of the stock center pipe.
Use 2.5" tube for the middle single section OR get a TRUE 2.5" resonator which will have a SMOOTH internal surface that is at least 2.37" inside diameter. The Top Speed that I bought is not a true 2.5". The outside is 2.5" but the inside necks down to 2.13" and has sharp edges in the flow.
See the following link for pics on the TS resonator issues.

You want ALL pipes to slip inside the pipe it fits into in the direction of flow OR be smoothly butt welded with no slip. Do not use slip fit against the flow.
You can replace the REAR Y-pipe, which splits from one back to two, with the link given above by spdrcr.
Any rear mufflers including stock will work. If you use stock select the 2.5" to 2.0" rear Y pipe to split the exhaust gasses and make any transition between pipe sizes SMOOTH.

1. PPE Headers = $600
2. 2 Magnaflow High flow shorty cats = $79ea (ebay free shipping)
3. PPE Cat flanges = $40 (shipped)
4. 6 Mandrel 45's = $129 (less shipping)
5. 2 2ft pcs straight pipe @ $4.50 a ft = $18 (less shipping)
6. 3 1ft pcs straight pipe for custom Y Pipe = $14 (less shipping)
7. Fabrication of custom Y Pipe = ??? cost me ($75)
8. Top Speed Mid pipe resonator 2.5" = $50 (shipped)
9. Rear Y Pipe = $69.19 (less shipping)
http://www.mandrelbendingsolutions.c...pes/Categories
10. Total Install = ??? cost me ($300)
Approx grand total = $1453.19
I know for sure there was another $75 in shipping charges. I saved alot on building the Y pipe myself. The $75 was for the welder guy. My exhaust guy is a real good friend & he spent 6hrs fabing mine. Any other person asked him to do what I did & it would be $400-500. LOL Damn kinda scary when I put a pencil to it. Headers cost me $400, so My total cost was, $1328.19.

Car sounds awesome man.
I'm really surprised about all that X-pipe, Y-pipe discussion, never thought the X-pipe would cause a loss in torque. Too bad I already have an X-pipe on order. O well, this car isn't my fast car anyway, as long as it sounds good, I'll be happy.
