Sounds Here:
In car burnout than WOT
Video of installed and idling:
Idle Video under Car (right click save target as..)
Hedman long tube headers, 3" Hedman extenders (pass side modified), 3" Purple Hornies

Use Lock washers on the header bolts, mine came loose twice

I can't tell if there is a vibration due to the bolts or if its just the V8 stroker with dual 3" pipes causing the rumblin...its a car alarms worst nightmare.

Did you have to have pipes custom bent from the headers to the mufflers, how long are they?

I know you used a x-tension right off of the headers but did you also use the to bring your mufflers closer together...like turn them side-ways or somthin?

See in this pic how they are turned inward and if you were to have them straight down it would be way to low.
