I had a RB wrapped header with a bonez free flow cat. Underhood temps were pretty hot, my strut bar and aluminum intake tube were so hot I couldnt touch them. I installed a borla XR-1 muffler in replace of the cat to cut down on the heat and exhaust tone and still underhood temps are just as hot. Sounds greaat though but I would have thought not having a cat would drop temps significantly...

I swear when I had the stock exhaust setup I could run all night and my strut bar and intake tube were only warm to the touch.
Am I TRiPpEn??? Fan still works... replaced the t-stat a few months ago...
Would removing the header wrap help at all??? Thanks!!

 

do you have your heat sheilds in place? its AZ **** gets hot

 

lol, for sure... that's why we only roll when the sun goes down. You know how it is... but yeah, with the exception of the exhuast manifold all the heat shields are in place. I swear temps got a lot hotter when I installed the header though...

 

YOUR TRIPPING HOMMIE! I cant touch my mazda trix bar either, maybe for a half second, but no more than that! Thats with beach temps in the 60-70's.

 

what i could use is a custom made heatshield for the header...

Anyone out there feel like fabing some up, I haven't heard of anyone doing it...

The other alternative would be to have the header ceramic coated, kinda expensive though.
