Exhaust Sounds too Raspy
 

Hi everyone,

A little bit about my BB rx8,

-AEM CAI with prefilter (for rain purposes)
-Exoticspeed Headers, 3in
-Exoticspeed midpipe, 3in (dual canisters)
-Mazdaspeed exhaust v1, not sure of pipe size

So onto my question/concern, recently i have installed my exoticspeed headers and the midpipe over 2 days. When i tested it out with all the parts listed above, i found that the exhaust sound was more raspy than i would have liked. i am not sure what is causing this and was wondering if anyone had any idea why it is so raspy or how to fix it?

here are two videos i made, sorry if the audio quality isn't good.

try a different midpipe?

Two ways...

Poke a hole in the muffler

Resonator so it is quite.

What is causing it is the fact that it is a rotary. A different mid-pipe and exhaust set-up will change it's tone and amount. BHR's mid-pipe, I am told, eliminates a lot of the rasp, but I have never heard one In person.

A 3in system is going to be a lot harder to tone down than a 21/2 . You really need some decent resonators in the midpipe . The ones you have don't seem to be doing the job.

I understand that it is a rotary and at first i didnt mind the raspiness but now its starting to get annoying cause its a loud raspiness.

could it be my catback exhaust making that raspiness?

try a racing beat or BHR midpipe

where can i get a bhr midpipe?

would people say that the bhr midpipe is better than the racing beat?

i have looked at video footage of both but the conditions were not the same and the audio was not the greatest.

ditch the catback, exoticspeed sounds delicious.

They are different products Souhjah, RB's has 2 resonators to do the job while BHR's only uses one that has no packing inside so it won't wear out.
Both companies make great products, it comes down to a matter of preference.

Bse50 - what do you mean packing? Could you explain?

Google exhaust packing, it explains almost everything!

U have a Single Resonated midpipe forsale if you want it

what is the make?

I had an Performance shop make it for me.. heres the link to it.. I decieded to go a different way on mine..

yeah right now im going to keep the exhaust set up i have now for a bit and see if i get used to it

OK, If something changes, Just keep me in mind. I can do OBO as well

alright well i have an option at the moment, should i get the exoticspeed r1t catback or get a bhr midpipe?

i can get the exoticspeed catback for 500 while trading my stock exhaust

Mid-pipe is the source of your rasp. Headers don't really help.

Exoticspeed makes a fine catback, though.

i have the mazdaspeed one though and can't tell which to get because i havent heard them in person

Souhjah have you been to any local meets? Chances are someone at those meets has one of the exhausts/midpipes your interested in. If your just wanting the rasp gone then go with the BHR midpipe as far as I know its the only one with no packing in the resonators so it should not develop a loud rasp over time like others do.

No i haven't been to the meets i have been busy with school lately and i have no idea when the meets are in Vancouver, British Columbia, Canada

any other ideas?
