American Racing Headers
 
Hi All,
Will these ARH 84134300LSTNC fit my 1991 A4 stock, with no issues?
and will they be compatible with 3'' Borla exhaust system? (or other brand)

Appreciate the feedback.
:cheers:

Anyone?

I can't answer your question, but no one would know better than ARH. I would give them a call directly and talk with them.
When I installed the ARH headers on my 96 I called them with several questions and they tried to help out.

Appreciate the reply, I’m overseas actually but I’ll try and contact them directly. I just wanted to check from a personal experience if anyone installed them. Thanks

I might be wrong, but when I bought my ARH headers for my 84, they had only one fitment for all the years, L98 through LT1. As mentioned, check with ARH.

ZEROVETTE7 02-13-2018 01:00 AM

Contacted ARH and they informed me that their headers (C4-84134300LSTWC) won’t be a direct fit and that it requires some modifications, I requested some more details and waiting for the reply.

If any one can shed some lights on the same that would be helpful as I’m gonna order them for overseas. And returning is not an option if they didn’t fit!
TIA

My headers didn't come with instructions, so they assume you have some Hot Rodding capabilities.
They also lacked in giving me the header bolts, spacers for AC, dipstick. But they gave you decent gaskets to mount to the heads and the fit and finish was very good.
So with that I don't know the difference between bolting the headers on an LT4 vs L98.
My catalytic converters were mounted further back than stock requiring me to make heat shields (ARH said that it doesn't need shielding if you can put a finger between the cat and the floor, I did not agree).
Overall good headers with plenty of clearance but you will have to think out of the box as they are not a direct replacement. I don't think any header manufacturer is a true direct bolt on.
Hope this helps.

thanks appreciate the feedback 👍🏻
Ill do some more research until I hear from them again, and look at other brands if any that might fit the ride.

I bought headman headers. The "fitment issues" required me to almost beat one of the pipes coming of a cyclinder, almost flat.

Checkout my old post on the ARH headers to get an idea of what you might need to do to install the ARH headers, it has some pictures: https://www.corvetteforum.com/forums...6-exhaust.html

The headers bolted to the engine easily and it has no clearance issues (no banging on pipes necessary) other than the cats were too close to the floor.
For difficulty installing them on an LT4 from 1 - 10 (10 being the easiest 1 being the hardest), I give them a 6.

Thanks for the info 👍🏻

I came across Hooker headers also while reading old posts here in CF any feedback on those?

And if I’m thinking of adding some bolts on mods, what size is more suitable for the ride:
1-3/4” X 1-7/8 primaries and 3” Xpipe
or
1-3/4” primaries and 2-1/2” Xpipe

with no cats Borla sys.

TIA

Don't forget, with many headers, you must make a spacer to rebolt some brackets

I went from Hooker Super Competition headers to ARH and my car gained a tenth and a half in the quarter. The stepped 1 3/4 to 1 7/8 worked for me. I have a 406 and shift at 6700 on a strip only car. I would think the 1 3/4 primaries would work in your situation.

ZEROVETTE7,

Did you purchase a set of ARH ??

I purchased a set for my '87 and have two fitment issues.

Michael..
