I recently put a Pedro muffler hack onto my car. the car sounds pretty cool/mean when you are on the gas. When you are WOT it sounds awesome. As I've had it on now for a couple weeks - I've had a chance to listen to it more at various speeds/rpms/etc.
I've noticed that as I roll to a stop, or if I am at very low rpms and am letting the revs drop back down to idle - there is a burble sound or a "hollow" kind of noise it makes. It might be normal, or it could be a characteristic of the "pedro" muffler. Not sure.
I have video of it, but need to convert the format to something i can upload to youtube. my camera records in ,.mov and you can't upload that. if i convert it, i'll put the video up so you can hear it.
do all the aftermarket exhausts do this? or does the pedro make a more raspy or bubly sound under these circumstances, or is it a "pedreo" exhaust thing???
i took the car into a parking structure to listen to it - and it sounds really noticeable when it's echoing in the structure. it's a bubly "hollow" sound and I don't notice anyting like this when I am on the gas. it's not there at idle. it's more associated with coming OFF teh gas, must be when the engine is under vacuum?
my stock exhaust dind't do this - but it may have had characteristics of this, just it was so quiet/muffled you couldn't hear it.
i wondered if the other aftermarket ehxausts do the same thing? or just the pedro mufflers?
crios - does yours do this??
