Exhaust way too loud!!
Asking anyone with experience in the matter how to qiet my exhuast down without going back to stock...
My rx8 was turbo. Too make a long story short my motor blew rebuilt my motor re-installed turbo turbo blew and now is na. I have intake, headers, racepipe, and catback. I kno thats why its so loud (ear piecering drone ftl!!!) but it was ok before i turboed it some years ago but i didnt have headers back then. Seems the headers make it super loud. I have the stock headers and midpipe with the cat coming apart. If i just swap the racepipe for the stock midpipe with gutted cat will that quit it down considerbly? If not i was thinking put the stock header back on and stock midpipe. Will i lose power gutted cat stock midpipe vs. racepipe? I have a agency power exhaust which is one of the louder ones for sure. Any info on the subject is appreciated, thanks.. |
Solution (or at least as close to one as you'll find) = BHR resonator.

A gutted stock cat will be quieter than an un-resonated midpipe. You likely won't have as high of gains as a straight pipe (argued in many other threads) but it will be better than a bad stock cat. If you don't mind spending the money, BHR is the way to go. FWIW, i run a gutted stock cat an HKS hi-power and don't find it too loud or with too much drone. HiFlite heard it on the way to DGRR. |
The agency power pipe has 2 resonators but there tiny so a lil bit quieter with the stock gutted cat likely not enough difference? mabe ill just switch to stock header and leave the racepipe in

what exhaust is it
|
Re anemiya sp? Header and agency power exhaust
|
Fuztupnz thanks for ur input hks is loud like agency power im hoping with the stock gutted cat, catback, and header itll be like just running the racepipe and catback
|
The cat is the big difference maker on our car. It sucks a lot of power and gas milage in my experience but it makes a lot of difference in sound levels.

The stock cat includes not just the cat body, but a resonator which is the key. A non-resonated midpipe will overwhelm even the stock muffler. |
Listen to these guys. (I'd run a straight pipe if I was allowed)
|
Lol i dunno man sounds like one of those old datsun racecars haha i was on the freeway for 40 min at 4k and my ears were ringing after

I bought inserts for in mine since certain towns they like to pull you over. Think they are only a few bucks. Makes one hell of a difference.

installed in your midpipe, it's a start anyway and probably better than a gutted OE cat pipe. Both a high flow cat converter and a resonator would be better though

Bhr pipe is pricy im gonna try my luck with the gutted cat well see tonight...
|
if you already own a racepipe/midpipe just buy the BHR resonator by itself and get it welded in.

here was my solution to my loud exhaust
i had stock cat, hks single exit exhaust and that was too loud. highway cruising i believe i put the stock headunit to low/mid teens to overcome drone. i modified and installed an apexi active tail silencer and i am very happy with it. i now can cruise with the radio set at 6-8. no drone, no drama. i will admit that actual tone quality suffered since the silencer makes it a bit brash in sound.. almost like a less attractive turbo spooling up. |
Here was my cure for a loud exhaust ................ Fit turbo :rock:

hmm, so gutted cat is quieter than AP midpipe? how is the raspiness of a gutted cat compared to an AP midpipe? my apologies for jacking your thread, OP
