Has anyone installed their headers themselves? My '90 TA GTA still has the original exhaust manifold on it and am plannin on putti headers on it this week. They're shorty headers if it makes any difference for the answer. Thanks

uhhh, yes, lots and lots and lots and lots and lots and well you get the picture. Do a search. What exactly did you want to know?

i installed them in my garage with some friends, plenty of people have even installed by themselves.

i thought 1 day, more like 3 with the catback and cats already off

sorry bout the confusion. I was kinda wandering about andy trouble I might encounter while taking off the maifold or puttin on the headers.

Might wanna take some liquid wrench or similar penetrant and soak the bolts for a while to lessen the chance of one breaking. Also, watch out for the fan switch. I broke mine when I was removing the heat shielding. Other than that, it's a straight forward removal/install.

make sure the headers you bought will work with your factory Y pipe or you will have to buy an aftermarket one to match them .....found out the hard way on my 84 with the headers we bought had to have a different Y pipe than the factory one

Pretty much all headers will require a different Y pipe. This is actually a good thing though, as you do not want to reuse the factory crap!

well my car already has a full flowmaster enhaust which was installed before i bought the car. this should work shouldn't it?

THEGENERAL

that is true the factory stuff is just too restrictive usually anyhow....lol.....

i remember when i ordered my headers at the time i asked if it would bolt up to the factory Y pipe and the guy said sure will with out a problem well to my surprise when i bolted them up it was way off..LOL

25THRSS

It should bolt up fine

90tagta

k thanks

90tagta,

I have the same car as you. Do you still have dual cats? Which headers did you buy? And please let us know how it turns out.

I'm trying to decide on a complete system from headers to tailpipe, but I'm having a hard time deciding if I should keep the dual cats (more $ but looks stock and pass emissions easier) or go for a single 3" all the way back, probably hooker 2055's for headers.
