i found a pair of black flowtech headers on ebay for my 83 cutlass supreme. are thay good headers or cheap junk?

 

My opinion is they're junk. The ultra cheap price pretty much tells you what their quality is like.

 

I have never used them myself but I have heard others complain of them not sealing at the head. I have also heard numerous people say that they are not parallel at the collector.

 

I had a set that i never used, but i heard a lot of people saying that they didn't seal at the head well, plus they hang fairly low. I sold them and bought stainless ones from Smitty. I haven't installed them yet, but the quality looks top notch.

 

That's what's on my car. You will be pleased.

 

ok. thats what i figured. what about headmen headers. thay are suposed to be a good brand.

 

To be honest your best bet for a budget header is Hooker.

 

Look at the Hedman Elite headers. Thicker tubes, 3/8" flanges and ceramic coated. I like my Sanderson shorties but they require custom down pipes. My Flowtech A body headers needed double gaskets to seal and the ceramic peeled and rust pitted pretty quick.

 

x2. To be honest I did a quick review of these headers when I installed them on my 66 and the fitment was descent very few bangs and they did not leak. I gave them a descent review. Now after a few hundred miles and retorqing the collector bolts several times they def have a flange leak (gaskets also changed). To me it was these or kooks which I beleive are now up to 1000. Personally I would not use these again, learn from my mistakes.

 

I ran a set of the Flowtechs for a while on my 87 with a SB. No sealing issues but still cheaply made. They ended up at the scrapyard after trying to give them away.

 

hay MXman112, you wouldnt happen to have another set of headers for a olds 307/350 youd give away would you?

 

i have a brand new set of flowtech ceramics for my 71 that are going to be installed in about a week. I'll let you know how that works out. Also getting the rest of the exhaust done as well. The flanges on these do look pretty thin. For 300 bucks I hope I dont have any sealing issues. Eventually I'll upgrade to higher quality later on..

 

Now more left laying around. Loaded up a truckload of stuff and off the the scrapyard it went. Had 2 1/2 inch exhaust, mufflers and tailpipes that went in the pile as well. Only thing that I was able to sell/give away was the x pipe.

 

i think im gonna get some headmen headers and do a x flow exhaust with eather flowmasters or round turbo pipes. then turn them out infront of the back tires with some nice 2 1/4 chrome tips. im gonna make my 307 sing.
