this weekend i had my downpipe and test pipe put on and afterwards i had what i thought was a exhaust leak. whenever i would rev you could hear a whisp of air flowing somewheres but after spraying all of the gaskets i found no bubbles showing exhaust leaks.
only place i couldnt check was where the 02 housing meets the downpipe but standing over the engine and reving you cant hear it so i doubt its there.

my question is: does the downpipe make the turbo more audible when spooling, even at idle and under 3k rpm?

 

im pretty sure it does, idk about it big wistle but it has to, atleast id think so cause its alot more flow

 

i understand the more flow and what not but realy i dont feel like it would make it more louder, just better response and that kind of stuff.
any better ways to check for a exhaust leak other than the bubble trick

 

get under you car, and stuff like that, and you should here a little wistle or some kind of air blowing noise if there was. i parents 3500 dodge had a exhaust leak and it wistled loud enough to hear around the block, lol.

 

lol sounds like my gf's durango
i think ill just stack it up as turbo noise and when i get tuned all ask my tuner if thats normal. hell he should have heard every noise under the sun

 

gwet a dump its sweet

 

yeah he should if hes a tuner, lol. after i get my full exhaust, catback, HFC, downpipe and maybe 02 housing, im gonna prolly have a shop do it and tune it at the same time. it might cost alot but atleast when somthing sounds wrong i can take it back to them
