Has anybody tried the stainless speed master headers on their JK? I have already had to replace the left manifold due to cracking, and I've recently replaced all 4 O2 sensors, and now, a few months later, I'm getting the p0420, p0430 codes. I have 118,000 miles on mine ('09 JK), and decided to go ahead and put new cats on since I plan on keeping this vehicle forever.

I was thinking of trying these headers with the hopes of not having to deal with the cracked manifolds anymore.

Any thoughts on these headers?

 

I've had nothing but bad luck with headers so I'd stick to manifolds. There's a company on eBay that has a 10yr warranty on their manifolds. I'll be buying when they're back in stock.

 

What type of problems did you have? I thought quite a few guys were running headers on their JK's and I'm not aware of any problems.

 

Bolts coming loose and melting plug wires. It was a constant fight to keep the bolts tight.

 

Just pulled the headers off of mine today and went back to oem style manifolds.
Same issue, melting everything under the hood, even wrapped them.

 

I've had RIPP long tube headers for 3 yrs with no issue

 

I think I got their last set, lol.

 

Yeah, had the flowtech shorty's from summt.
