I just got done installing a mopar BOV on my SRT-4(what a pain in the ***!) and there are 3 circular holes used to vent the air into the atmosphere.. i was wondering if there are any inserts i could buy for those holes to make the BOV sound different

 

I dont think so i checked ebay and there was none usually if it exists it will be on there

 

ive never head of any.

 

I *think* that PTPerformance has a way of modifying the Mopar Blue plate. I may be something that doesn't blow off as easily. you could check their website if you wanted to be sure, though.
