I am building a L67 to put in my 88 Formula right now, and on a budget so I figure my best bet is some SSAC headers for $225 shipped since with a new flex joint, clamps, and lots of RTV these seam to get great reviews in the Grand Prix community. Now I was wondering if anybody has used these headers in ther 3800SC Fiero? I am sure they will have to be modified to fit especially if I want to keep my trunk... Any dot have some pictures or anything I may find useful? Thanks for any input!

You mean these headers?



Note that I cut the crossover pipe in three pieces and moved the joint for the front bank back further to gain clearance to throw out bearing release lever. If you are running an automatic you wouldn't need to do that but the crossover did not fit at all the way it was shipped and you probably want a bellows in there anyways. Mine came out really well in the end.

Also notice that I cut the bellows off the outlet as well. It hangs down below the cradle otherwise.

I was not able to avoid cutting the trunk but I figured that if I was going to go through the effort of headers that I wasn't going to sacrifice downstream in the exhaust system. I kind of doubt that even with removing the bellows there would be clearance to the trunk.

On a budget? just use the stock manifolds. Just as good, no trunk cut either.

I am going with XP cam and E85 with supporting mods, so I really do think headers are a good idea.

Jefrysuko, thanks a ton for that picture. Is there anyway that you could post a picture of what amount of cutting you did to your trunk, Thanks.

I cut out the entire lower section which gave me enough room for the V8 F-Body Magnaflow (3" in and dual 2.5" out) muffler and keep it up high enough that it couldn't be seen from the rear of the car. I don't have it in the car right now so I can't really take a picture of how it all fits.

Almost correct. The rear 3800 manifold is non-restrictive and flows well but the front cast iron exhaust manifold is restrictive, The system can be upgraded with a ZZ Performance Powerlog manifold for $159.00 and that producs a very good flowing 3800 exhaust ystem. . There is good info on this on the ZZ Performance website.

Take a look at the rear manifold cross section cut and ther write-up.

I already have ordered headers, 225 shipped. I am a sheetmetal worker by trade, so modifying things of this nature are not an issue. I just like to have a decent heads up of what I need to do, so that I have less figuring out later on lol
