Project Evil Tow Rig - '87 CC SRW Conversion

[Evil Trailblazer SS]

Alright, question for you guys...

The Doug's Tri-Y headers will be here in a couple weeks and I've decided for emissions compliance, I am keeping the AIR Injection. I am going with dual 2.5" with H-Pipe, dual Magnaflow Spun Cats (Metallic) #59956.

My question to you guys is this, I've always run Flowmasters on my older small blocks and even my last crew cab got the 70 Series Big Block mufflers. My Dad's 454HO has the same headers and the 70 Series (without cats). My concern is that my last crew cab was WAY too quiet with the cats and 70 Series. So this round I am entertaining other options...

I love the Magnaflows on my Trailblazer SS and hate Flowmasters sound on ANY LS motor, but who has Magnaflows on their big blocks? Sound clips? My main concern with the Magnaflows is that I used them for my '85 3/4 ton Suburban and they sounded like blown out glass packs from the minute they were installed.

The truck will get a complete head/cam/valve train upgrade with a bump to right around 9:1 but I want a good sound now as well...
