it looks to me you bolted the exhaust hangers straight to your floor? doesnt that cause excess noise or vibration?

He's got a stroker motor with whats essentially an open exhaust.Don't you think it will have excessive noise and vibration no matter where he puts the hangers?Besides, where else would he put them?

Its got rubbers my friend

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.

I notice your collectors are right under the crossmember, how is your ground clearance?

Whahahahahaha! The car is doomed already. This is my toy 3rd gen. In the future I want a real sweet RS with low miles and NO RUST! Especially when I get older with more money I can do stuff right.

Correct. I don't mind putting money into the suspension and drivetrain because it all will bolt onto another 3rd gen. Like a paintjob and all the other materialistic BS is a waste of money for this ride.

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

Mine has holes in the bottom. Not through the floor board yet, but it won't be long.

No I didn't get them custom bent. I just installed the header extenders and bolted them on. I did have to do some fabrication to the passenger side extender by shortening it and rewelding it. Other than that it was a pretty straight forward install.

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?

Oh yeah, the header extenders had too big of an s curve so I turned them inward to bring them up and in the process it brought the mufflers to the center more.

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