True Dual H-Pipe Dump. Moroso Spiral Flows OR Dynomax Bullets? Who's got what mufflers on thier true dual dump set up? I was thinking moroso spiral flows or dynomax bullets for fitment and all around sound. Any suggestions?

Huh?
Heh sorry just playing around, I'll treat this as another question. As far as fitment, you won't find another muffler that fits better or as easily as either of those, they are the same dimensions (I think?) at least the same width. Again the Dynomax are loud and mean and droney. The Moroso's are more refined, still very agressive but less VOLUME, ya know? Excellent sound though.

I have run both. The Dynomax mufflers weren't as nice as the Spiral Flows. The Bassani Bullets are the best though, I have them sitting in the garage waiting to go back on. **** my neighbors! haha

Yea you will lose mega HP 
My buddy is leaving some on the table with his SC'ed viper, but he's also pushing 600+ rwhp. You might lose some hp, but I would be very surprised if it was enough to even be felt. I have some vids on video.ls1tech.com or whatever the site is, you can find 'em by searching for "spiral" it's the black formula. I am far too lazy at the moment to find them
