Do you guys usually change out the studs to new ones? I was looking on here and came across these. Any good? https://honda-tech.com/forums/sale-1...-kits-3342685/

 

Speedfactory has some really nice titanium stud kits. Decently priced too.

 

$204 for some studs? Why would you go that route over 1/4 the priced stainless?

 

Woah.. Then I think they were on sale when I first saw them they were 89 for the set.. Lol! But, titanium, yo!

 

No, I just use the OEM studs for both manifolds. I have switched to Stage8 locking hardware for manifold-to-turbo and turbo-to-downpipe because I always had bolts backing out before I changed over. I personally wouldn't use titanium hardware on the exhaust side. If you're having issues with your exhaust hardware and need to upgrade, inconel is what you need to look for. But stainless steel has always worked for me.

cheap and been working fine for me. ONLY complaint is the nuts are 1/2 as opposed to 12mm or something lol

 

Any opinions on the marketplace ones? I like the allen key insert like ARP

 

Goautoworks! Inconel studs and copper lock nuts, just did this on my car. Pretty affordable too.

 

Those aren't bad either. I used the ARP Exhaust manifold stud kit.
They were fantastic on my JDL Auto Design Exhaust manifold and held without any braces weighing in at over 22lbs. About $100 and from a quality company.

I also went with ARP stainless studs and nuts, Although I purchased them individually instead of a kit. I ended up paying $120 for 19 studs (2" long, 1.75" long), 10 12point nuts and 10 chamfered washers. I'm using copper lock nuts for the exhaust though.

Just did a set of ARP studs while the exhaust was off of my daily, kit 400-8023, about $102. Replaced mainly because the old fasteners were bolts and it seemed like some of the threads in the head were starting to get a little tired. Never mad about spending a little extra for ARP stuff.

 

I use the Dorman 03415B for both the Intake and exhaust manifolds.

Does it back out.....NOPE
Does it cost $100+....NOPE
Do I care if it's titanium material...NOPE

 

I see guys on here using copper nuts on the exhaust. Never really observed this anywhere else. What’s the benefit?

 

From what I remember, it was the nylon locking center was made them unique. I've had them installed on other cars, but I"ve never used them.

 

I use stock studs and nuts, price free. No issues

 

They dont rust and, they STAY TIGHT.
