'88GT V5 2.8L - 40k miles, being revived after many years stored in the sun
The car is running fine now, but it lacks power. A less restrictive exhaust including an improved muffler might do the job. Does anyone have an old set of headers or a well-ported original manifold lying around? Condition is unimportant, but price is (as usual) critical.
Its very easy to port your own exhaust manifolds with a dremel and hogging bits. I did the trunk side one in a good afternoon. The front side i had a mechanic take off for me, i bored it out, and he installed it back on. Get new gaskets though.
I just removed a stock set off of a 2.8 88 GT motor. Has a crack at welded joint (normal) can be fixed. Otherwise in great shape. Email me if interested. I can send pics. we4buick1547@yahoo.com
