ok I'm new to the efi cars and I'm puttin on the o/r h-pipe from the 85.My ques. is do I have to hook up the emissions pipe that runs down to up under the car or can I just get a pipe crimp it up at the top(I already have the stock h-pipe off)

 

Well if you are buying a off road H-pipe they will usually have a small tube built in for your smog tube to connect to.
vvvvvvv






If you are having a H-pipe fabricated by a local exhaust shop then I would just remove your smog pump and all its attachments. I'm assuming you don't not have to pass smog or inspection in your area.

 

well see I already have the o/r h-pipe and it has the pipe built in but it's crimped do I need to take a piece of tubing and crimp it for up under the hood

 

You should have a rubber tube already running from your smog pump to your H-pipe if you have a stock midpipe in there.

 

I'd get a smaller belt and ditch the pump.

I had my trucks exhaust done, and now the air pump just dumps into the atmosphere, and the damn thing humms like a ****, next on my list is a shorter belt so it doesn't operate anymore...

 

take all the emmision stuff off and run a short belt. just be sure to plug the holes in the back of the heads

 

I'll prolly get a short enuf belt that I can take off the a/c too

 

Its not that easy there my friend. If you try that you can't run the tensioner and then you can't get the belt on. That is why you see people with compressors that are unhooked but still in the belt route. Get a a/c delete for like $45 and then have fun .

 

God, I can't wait to make that damn air pump stop, it's ridiculous, once the motor hits the rpm range the exhaust comes in, the noise from the damn pump drones it out. ERGGG

 

is it the p/s pump that you can bypass instead of the a/c
