Rick, surprised to see it didn't all fit under your bonnet. Mine fits just fine and the tightest clearance is about 3/4-1" to the back deck area. No heat issues using the heat barrier I applied.Tom - My exhaust was supplied by RCR but I had to modify the 2 rear tubes to have sufficient clearance from the rear deck. I have to weld all of the joints together so when I do that I can add the slip joints. My intake has 58mm throttle bodies instead of the 52mm bodies usually mounted to the intake. My engine is built to live at 7,500 so I needed larger TB's to provide air at high RPM's, HP starts dropping off from 625hp @ 7,500 to 575hp @ 8,000 rpm.
You're gonna love the sound of those trumpets when they start to sing about 4500 rpms...intoxicating!
Definitely go slip joints with the potential of that motor. That ECU needs accurate O2 data to run right.
