EU3 D17A2 Exhaust

**SHU-ES1** · 10-09-2009 12:42 PM

Hey all,

I just recently completed my system and put in a 2.25" Mild Steel Catback exhaust with one hot dog resonator (only $110). I like the deep smooth tone of the Magnaflow 14818 Oval Muffler at the lower RPM range, but I want to know how to get rid of the raspy, farty noise that it emits when I get over 3.5k RPM? I use to have a 2" Apexi N1 Cannon which was alot x 10 worse than this, so I changed over to a bigger size piping and muffler but it still hasn't got rid of that noise at the higher RPM. Can anyone suggest anything that I might have to add/remove to get rid of the noise but keep the deep tone, and volume? My setup is X-Force Header with 2.25" outlet, 2.25" SS downpipe with 100cpsi Venom HiFlow Cat, and now a 2.25" Mild Steel Catback system with one HotDog Resonator. Any feedback/comments/tips would be appreciated.

I've just added a few pics, and one video to give you guys an idea!

I think you'll need to add an extra resonator to get rid of it

twinloop muffler, middle offset muffler! or K20 it

add and oval mid muffler

will the offset muffler or oval muffler restrict flow? i'd like to keep it as free flowing as possible. so you don't think another hot dog muffler will do the trick? also, i'd like to keep the volume that its at, it's not too loud on idle on and screams at WOT. so you think i should get an oval muffler? offset/centre or offset/offset?

edit: oop, saw you put middle/offset.

thanks nepolian. that's like a hotdog resonator? is there anywhere i can purchase them here in melbourne? will it make the exhaust quieter with one of those? i don't want to make it so quiet, that it'll be like my stock exhaust system.

This website delivers pretty cheap, just sign up to find out how much! It is chambered so it takes away some of the "bark". The bigger the muffler, the better it works. If you can fit a 6" style centre muffler it'd probably work the best.

Resonators do jack in respects to sound deadening!

oh, i dont really want to make it quieter. i want to get rid of the raspy/farty sound that occurs when im over 3k. will this do the trick?

Sorry dude, cant really have one without the other. But a chambered muffler will lessen the bark (fart) but wont completely get rid of it! Youll probable enjoy the tone more anyway....

Go to your exhaust shop and see what they can fit under there. If its anything like the EP3, youll have heaps of room. Enough to fit a 6" offset straight through muffler. This will give you flow and will give a deeper sound too!

should i get rid of my existing hotdog resonator because its one of those cheap ebay ones, and is only about 6" long and replace it with an oval straight muffler or have both? sorry for being so annoying with the questions.
