Headers to 2.5" Ramhorns - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Someday I'll need 'em for my 'vette. At $29 each, I placed my order. What a deal if they acutally fulfill it.

smbrouss70 · 03-06-2009, 10:34 AM

FYI, JC Whitney said the same shipment date for me, but after I ordered, it told me that they were no longer available. I called and spoke to someone about it and they told me that it looked like they were not able to get them anymore. So I shopped around and found them on Amazon for $51/ea. Also JC Whitney only listed the 674503 which is the right side which I "believe" is the one with the heat tube in it. Amazon has both so I ordered a set of the 674504's.

I ordered the ....03s. I thought it was the right side that didn't have the tubes

WHICH ONES

smbrouss70 · 03-06-2009, 10:51 AM

According to a post by PICKMUP when he was selling the kits, the RH side does have the tubes. I'm no expert, just going off of what I've read. One thing is for sure, one of the 2 of us will have tubes.

I will PM PICKMUP and ask. Maybe one of us can change our order depending on the answer.

Only leak I have is at the collector, but need to get some good gaskets before I complain too much. No problems a the heads though.

LT1 had excellent plug wire boot shields, can be had for like 6 bucks a piece or something like that.

Texanidiot25, those were the parts I found at Speedway, also. They are some good looking ramshorns, but pricey. Is that what you are running?

Fun in Dirt said he ordered some in the $60 each range, and I couldn't find them.

Just regular cheap-o headers, when I bought my truck it was already set up for headers. (Had no motor/trans)

fun in dirt · 03-08-2009, 11:23 AM

When I went back there & did a search "exhaust manifold" for them this morning I could not find them either; only the same ones Texanidiot25 referenced.
But they already sent me a shipped confirmation Friday. The ones I ordered from Speedway were part #9300327-R (still not clear on whether I should have ordered lefts instead). I punched that # in & they still show them http://www.speedwaymotors.com/2-1and...olds,9133.html
My total shipped & all was $140.25!

Post up, when you get your order in

70rs/ss · 03-09-2009, 05:27 PM

I placed an order through JC Whitney, they let it go through, I'll see if I get them?? I would've thought I would have been rejected at the online order phase if they were out of stock?? I'll see, if not then i haul the part number to the local parts place and see if they'll "price match" the online JC Whitney price??

If they let mine go through, my wife may be pissed at me. I'll have 2 sets being delivered.

fun in dirt · 03-10-2009, 12:05 PM

My set came in from Speedway yesterday. And now I know that it's not the right side that you need to order, get the lefts. But oh well, they look good & it won't be too bad taking the heat risers out... I hope!
Maybe I'll work on getting the brackets & casting marks ground off this weekend. We have some ceramic coating stuff left in the shop from another project, so I'll probably coat them with that.

Thanks, 2 left sides it is!

Obviously you are going to have to show us some pics once you get them coated.

smbrouss70 · 03-12-2009, 08:53 PM

Mine came in yesterday! Dorman 674504 is what you want, if you don't want the heat tubes.

This needs to be brought back to the top again for everyone.

The manifolds from Speedway Motors are the Dorman manifolds, just so everyone knows.

Looks like they are 60 bucks ea. in my new speedway catalog. Thanks for bringing an ol' post BTTT '49gmc

TonyJohnson · 05-28-2010, 09:24 AM

Currently I have stock ram horns with custom 2 1/4" to magnaflows and then dumping behind the rear wheels. I picked up a set of the Dorman 204s, ground them down and they're ready to go on, but I need to mate them to my 2 1/4.

Speedway recommends using header collectors for mounting the exhaust to these. Anyone here use them? Any other ideas? I thought about just using some stiff wire and making a template for 2 1/2" head pipes and then using a slip fitting on the other end to clamp over the 2 1/4... What did you guys do? Would I lose much staying with the 2 1/4 after the magnaflows?

**LostMy65** · 12-03-2010, 11:44 PM

My 65 that I'm still looking for had classic corvette 2.5 RamHorns.

AlaskaMatt · 12-04-2010, 05:10 AM

Bookmark.

Funny I was reading this same thread a week or two ago after searching for header options. Good info here.

**LostMy65** · 01-28-2011, 11:25 PM

So is everyone happy with the Dorman's?

Are you getting the DOR-674-504 or DOR-674-503?

These are the 2-1/2" correct.
