Only being able to talk from the SLP'*, the install was a dream. Easier than stock manifolds IMO.
The trick, get a lift or jack the car up nice and high. Unbolt the crossover, hop under the car with a long extension (close to 3 foot) and a ball pivot deep 6 point 13mm socket. With a helper up top to guide the socket to some of the tougher to see bolts, you'll have the rear manifold off in 10 minutes.
The SLP'* rubbed on a nub in a heatshield on the firewall. Upon inspection at Intense (thakns again Tim
)...there'* NOTHING behind that nub, quick adjustment and the nub was no longer an issue. Nub~~>
PDad mentions you'd want to take the movement out of the motor if possible. The 2000'* have a ton more movement than the 92-99'*. Although I chose to solve the trans mount clearance issue and remove the movement at the same time. I have about 3/4"-1" clearnance to the headers.
I don't have pics of the DP area (all part of the rear header on SLP), but it looks about 1,000 times better than Mikes pics. Whether the PS lines are different or something..They slid riight up and in w/o a squeak on the back of the motor.
Literally, the only issue was the front trans mount.
