Uh, drill holes in your muffler? What do you mean louder? Exhaust wise? Remove restriction. The TRD is probably one of the quieter aftermarket exhausts out there. Refer to the exhaustive exhaust pipe thread for more information.

that worked for me. More in cabin noise, but not too much. also more ext. noise when you're higher in the RPMs, but I have the 4-1 so it "kicks in" in the high RPM range. Maybe the 4-2-1 header will have more in the low-mid range, when it works more.

TRD exhaust is really quiet, you should get a new exhaust, an header, and you should be pretty loud

yeah, I can't wait to get my intake and exhaust now.

so heres what ive done ive put in a k and n filter removed t charcoal filter and pulled off the snorkel it deffinatly sounds way better aroudn 4 grand but im worried about water induction now. im in oregon and it rains alot here do i have to worry about water gettin into the box and from there into the engine....also would swiss cheesing the lower box help air flow as well as sound?

I have the MMW 4-2-1 header and it really didn't do anything for sound. niether did my SR injen.

what made the biggest difference for me, was the resonator. I went w/ a full cat-back custom exhaust and originally, I didn't install a resonator. way too ricey - and loud. Then the muffler shop installed an 18" resonator - really a glasspack - and now it's deep and low.

you could do the same in reverse - have a shop play around w/ different size resonators. probably a 12" would be to your liking. or just drop it out all together.

buy a crappy e-bay 25$ muffler, or go to your local auto parts store and buy the crap AEM muffler... your car will sound really ____ty... i mean loud...

i have strup headers, fujita sri, and trd exhaust and its decently loud when i get on the gas.
