Rangers,
I’m considering keeping my original exhaust on my 89 2.9L including the cat. Any thoughts on how to go to a 2-1/4 or 2-1/2” exhaust pipe and muffler after the cat and the effects?
I have a 58 mm throttle body from a 86 to put on to replace the original 54 mm and I’m going to modify the air box to get more air to a K&N filter. I want to make sure the increased exhaust has a more efficient way to get out to increase performance and not backfire.
It’s my plan to adjust the exhaust first since the throttle body is just a four bolt process and cutting the air box is just a couple of hours.
While you are at it, any thoughts on upgrading the rubber pipe between the air box and the throttle body would also be appreciated.
