Heat could be an issue on coated vs non coated. Dont recall anyone that has actually tested the diff. Maybe someone will chime in.

 

I had mine coated and commented on another thread that I thought my engine compartment ran cooler since my fan did not kick on as much as usual. Many thought I was crazy but still feel the same way. Not tested just a personal observation.

 

I put miltek sport on my c4s
Very nice system

 

bump for good service from Darin. I put on a system that's not exactly in line with my use & shocker! it's too loud . So, now I have my OEM cans in the mail & should have them in a few weeks. Should have done this on day 1.

 

I replaced my coils and plugs last week, took the exhaust off....the previous owner (who I don't know, bought it from a dealer) did the mod....and based on the quality of work, I'm going to say that this is Darin's work. Haven't seen it before, but everybody else who posts pictures of a local shop doing it is nothing like this.

I love my Fister!

 

Seems like this may be next on the to do list

 

Update: installed these last night and am really impressed with the sound, not to mention the service & ease of working with Darin. I've spent some time messing around with different mods to breathe some life into the sound and this mod is the single best $ per smile factor I've found.

 

Yes, that certainly is our work. I am glad you are enjoying them!

Very glad to hear you are happy. Thanks again!

 

I'd really like to get a set of these. Has there been any discussion about the change in back pressure impacting engine performance?

 

My intention with the fisters was sound only, but I did see a youtube video this week where a guy tested fisters & the IPD plenum against OEM. He noted 3rwhp improvement with the fisters (unkonwn with IPD due to testing issues) but it was a one-day, side-by-side test. I think a better test would be to let the ECU adapt to the different hardware and test, but I'm not a dynocologist.

 

mine have arrived! can't wait to install them.

 

I just got mine in last week, LOVE THE SOUND

 

 

Great, thanks for the info. I wasn't really concerned with power gain but rather loss in performance by changing back pressure without adjusting anything else like the tune. It sounds like that isn't the case.

 

butt dyno readings are excellent!
