loud exhaust
 

Hi all

I just fitted a 3inch Cat-back Stainless/Steel exhaust, looks mint but it's too loud and drony. on the freeway i can't stand the sound of it. should i get a high flow cat or a full exhaust from the turbo back( so it would'nt be to loud)

I'm new to this so thanks for any info

High flow cat or a full exhaust would make it even noiser wouldn't it?

Apparently X-Force headers keeps the boxer rumble down a little bit? The cheaper alternate is ear plugs :D

Is it a canon muffler or oval muffler?? makes a difference. I've got a full turbo back stainless system from RMS with an oval muffler and the sound is spot on - not too loud, no droning and a great deep boxer rumble.

i had a hks hi power turbo back exhaust fitted with no cat.. then fit in a high flow cat a few months after that, and i found out that the cat doesn't make any difference in the noise level.

Muffler tip diameter also makes a pretty significant difference to exhaust note. A 4" muffler tip is considerably louder and "dronier" than a 3" tip for instance. Having more resonators (hotdogs) will also reduce drone.

Alternatively just have a straight through straight pipe so that the noise just drowns out any drone :)

yeah agree with scoobysix.... i fitted a resonated 3 inch tip after having a 6 inch dump on my first wrx and passed the pits...that was the only change to get my yellow off

get a bigger subwoofer !

also might want to get it checked out at an exhaust shop, as the exhaust might be touching the body of the car, whcih will also cause it to get droney

WRXWGN hey
did u buy brads old car? or u a new dude

carls

i believe this is the purchaser of the aforementioned persons vehicle

2.5' muffler should eliminates the drones without sacrificing ponies

What ya been smokin black my03? Everyone knows that 3 inch is optimum for a wrx.... if the wagon has any mods at all then 2.5 wont be enough at the very top of the rev range.

Also in quite a few muffler tests a bit of 4 inch or larger pipe often works well at cutting noise in addition to the existing mufflers etc. Thats how they passed this falcon on autospeed...tried several diff exahust combos before inserting some 4 inch bit of pipe

i think he means the muffler tip

Stace had a muffler tip smaller than 3" and it was stifling his power output. I think a minimum 3" exhaust diameter at any part of the exhaust is important.

If you had a split muffler with two 2.5 inch tips then yes, it would reduce sound wihthout sacrificing power assuming that it was well made where it splits up.

Just fit a resonated 3 inch tip and a long hot dog muffler somewhere else in addition to the other muffler. My car is quiet as when idling with the 2 mufflers and reso tip i have.

Thanks all,

im going to get a resonators or hotdog fitted to reduce drone. Muffler has a 4" tip (i think)

no i didnt buy brads old car im a new dude

oh then welcome :headbang:
