    For those with headers do you have the common tick that pushrod motors have at the collector when your headers were added?
    My car ticks now with 3k miles on her and its annoying not sure I can take more of the of the same but louder. I've sat on my headers for about a month as I collect all the parts needed for my build and yes I am going cammed cause its cool!

    I ask the question because I am thinking swaintech white exhaust coating being very thick will dampen the header pipes which may muffle the tick but its a very expensive solution and I need some first hand knowledge before I start assuming and spending money needlessly.

    The vid below (not my car) has the noise in the background which sound like crickets ticking and is cammed as I intend to.

    I don't have headers. Just jba catless mids. After dyno tuning my car has that same sound. A little bit of a lifter tick type noise.

    In every car I have cammed (mostly old school American muscle cars) There has been an increase in valve train noise due to the higher lift/longer duration of the performance cam. Having long tube headers only exacerbated the sounds which were slightly muffled by a freer flowing exhaust. Having the coating put on your headers (which are most likely thinner than the stock manifolds) should help some with that.

    Did whomever owns that car change the valve Springs with the cam swap by chance? I had an old Buick motor that quieted down when I swapped the springs to a more sturdy beehive (spring within a spring) style as well as adjustable pushrod length. I don't know much about the modern cams with their phase limiters and such, but I would check lifter preload and pushrod length with any cam swap. What are the specs on the cam?

    Pretty sure there was a disclaimer saying it wasn't his car.

    Funny, I had my head under my front wheel just an hour ago listening to what is called "header ping". I am running American Racing long tube headers and I did have questions about exhaust leaks after the initial install. The installer did go back in and tighten them up which made things a lot quieter. The tubing used in headers is pretty thin and it will magnify the sound a little bit.
    As far as the video that was posted, that is closer to what mine originally sounded like which I thought was a bit too much and after they re torqued them most but not all of that sound went away.

    How much longer after install did they have to do that? Strange

    I could have been a little bit more detailed. I did the E85 conversion and I kept experiencing my eyes burning, smelling and tasting the E85. At the same time the exhaust tick kept getting louder. The installer kept denying it and claiming that it was normal header ping. I took it somewhere else and I had them do a smoke test on my exhaust system and they determined both headers were leaking. Took it back to the installer they they told me the gaskets were blown out. So basically just tells me that the original mechanic did not torque the bolts properly on the install.
    It is my opinion that be header ping on the white Hellcat posted in this video it's too loud and may have a leak at the heads.

    I'm on the fence with doing long tube headers and cams. What are the pros and cons?Has anyone changed their cams yet?

    Pros:
    Real good for you
    Cons:
    Real bad for Mustangs and Camaros

    Great mods for your car can't go wrong with long tube headers and cams.

    Did you get your cams from HHP? I'm running 2.85 upper pulley with tune stock exhaust will I need to change injectors?Who did the install?Can you send video of the sound of your car?
