Just get rid of the EGR valve and tubing as well as the AIR tubing. That'll clean up the engine bay as much as washing. There's a vacuum port mounted on the left rear of the intake that you'll need to cap off, as well as putting a freeze plug in the EGR hole, but that's about it. Doing so will also facilitate spraying and wiping.

Hey guys going from my high flow catted y pipe to the catless y pipe and no EGR on the headers, I notice a lot of droning and inner vibrations in the car now whilst on D and at idle, while in motion or on any other shift at idle the droning and vibrations go away, is this normal? I have poly motor and trans mounts. I figure it's just cause there's more power going through the pipe? Just making sure

My experience the Speed Engineering stuff is pretty good overall for the cost. Y pipe may be pretty fussy to get fitted. My local performance shop hates Speed Engineering in general due to the random fit issues that occur.FWIW - I've had exhaust holes fixed before by asking the shop to weld a washer into the hole. If the hole isn't too big that can work as a band aid for a while. Probably will depend on how rusted out the metal is if that can be done.
Saved me having to buy a new exhaust for the wife's old Grand Am a time or two

I wouldn't have been able to patch the hole because the pipes were badly rusted, photos are above^, nevertheless I decided to go new pipes anyway for the case of when I resell
it all worked out, and these are ss 304 so i should be good from now on
