turbo exhaust annoying- input please!
ok guys i ran an open down pipe for a little bit and it was getting old(sure it was fun a first) the damn thing sounded like a bike at 9k!
anyways i decided to build my own exhaust.. 3.5" so i gathered all the pieces, and this weekend i decided to weld it all up and see how it sounds. its horrible! im not happy at all.
heres what ive got. maybe you guys can point me in the right direction (ive never attempted to make a turbo honda quiet...)
starting up front..
top mount t3 with 3" down pipe with a 3" flex pipe to a 3.5" pipe Vband clamped to "catback"
open tial wastegate(i think this is a issue with being loud)
and from dp back is all straight 3.5"
nice thick piping with all mandrel bends. nice clean welds and all connections.
ending with a 3.5" turndown right before the rear control arm.
in the low rmp the car sounds ok. its quietER than it was but not near what i thought it would be (i know the turbo muffles out alot)
but in vtec the damn think sounds like an all motor car with a buddy club exhaust, its very raspy and sounds just gross. so im needing some input to get this thing quiet. im not to familiar with mufflers on turboed hondas so i was wanting some input on which ones were more quiet or the pros cons of any out there. i know it will help the car being quieter under boost if i tapped the wg dump into the exhaust but under boost im not to worried about it being so loud, i just want the raspy to go away. besides i dont even boost till 5k so its not an issue really. just looking for a cleaner sound! any input would be greatly appreciated guys! i threw up some pics to give you and idea of where im at, at this point... thanks ht.

If your were 3" I know vibrant makes a resonator and turbo muffler. Not sure in 3.5". That would help out alot. Your pretty much just straight piping with nothing to actually help noise. And yes its always gonna be loud with open dumps under full boost. You could recirculate into downpipe but it usually results in less power

I had a exhaust like that on my wife's sohct but it was 3in all the way back. That thing was annoying loud! It was louder than my car 4in uppipe out the hood.. I ended up putting a 3in muffler on it . It sounds way nicer not raspy at all.

Re: turbo exhaust annoying- input please!
thanks guys, yea ive looking for a muffler but everything i keep running into thats 3.5 is like a full on race muffler which im nervous to buy because race mufflers usually dont help with noise much haha... anyone else with 3.5"?
maybe i shouldnt have tried to be different with the 3.5 i keep finding all kinds in 3"

Re: turbo exhaust annoying- input please!
That $25 garbage isn't going to do much... you obviously need to run piping on your wastegate or even recirulate it. When the wastegate opens you are "open header"; think about it. The only way to get rid of rasp is with real mufflers and true resonators. Not "Vibrants" sorry excuse for one...

Re: turbo exhaust annoying- input please!
Assuming you are talking about "Vibrant" - Not at all, I run their muffler and resonator on my Turbo vehicle. They are built exactly like a "glasspack" and not a true resonator.
VS.
...or a different design -

There are two ways you can address this: some people just get a small diameter muffler or resonator for the dump tube, but my preferred way to quiet it down is to reroute the wategate dump into the downpipe. Here's an example: https://honda-tech.com/forums/forced-induction-16/dump-tube-flex-tube-3030176/
For my setup I need to be able to drive down residential streets late at night without pissing people off (DD). So i have a muffler and resonator installed post-turbo.

Re: turbo exhaust annoying- input please!
I installed a recirculated dump and a catalytic converter back onto my teg. It has a 3" thermal R&d exhaust. Sounds excellent now but I am thinking about changing the muffler anyways. The thing is like 14 years old and I know the fiber is probably done.
I cannot stand the buzz and refuse to have it.
