Can you speak to under-hood temps?

The price on these seem decent comparted to buying some other shorties & sending them out to be coated.

Definitely cooler. The ceramic coating helps keep heat inside the header. Some headers also have ceramic coating on the inside and those work best for heat retention but are also the most expensive.

To my knowledge the ceramic coating on headers is for heat control.

I'm pretty sure the only difference between the two ceramic coatings is the look, so if you want shiny parts on your engine, get the polished one.

Curious to see what they email you back though.

Same.

We don't have CARB or CAFE or whatever in NH, but we do have an annual Safety & Emissions inspection. If I had the $$$ I'd get LTs with cats. because I care a little bit about the environment. But those are like $2500+ after you get them coated, because road-salt. That's a lot for this guy.

Same, I like the sound of a catted exhaust personally, and the high flow cats are so much smaller, easier to package.

Good to know, I don't like shiny parts though lol, but I like best bang for the buck performance...tough decision

EDIT: their website says out of stock temporarily, but summit racing says they have nine sets, and listed 50 bucks cheaper than BBK

EDIT:EDIT: the summit pro account knocks another 40 bucks off!

$508

haha nice.

I feel the upside of cats is the lack of smell. I got so sick of smelling like exhaust fumes walking into restaurants, I put the stock ones back on my motorcycle lol

have kinda left them on everything since, as long as I can get them to flow decent, I'm OK losing 4hp haha

Peep my build thread for lots of roller pics!

Sooooooo, I bought a PPV ...

RC, great looking PPV. I’ve spent the past few days enjoying this thread with your continued mods. I too have the silver PPV, ‘14 year model. I’m working through some aesthetic issues in the interior and exterior as well as establishing a maintenance baseline. I like the plentiful...
