Loud! exhaust NEED SILENCE!

isaac_in_tx · 02-08-2009, 10:46 PM

well i just recently installed an obx421 header on my focus, and a flowmaster muffler, and its reallllly loud, i need to quiet it down alot, im running on stock piping, but tomorrow im going to get that upgraded to 2-1/4 to see if that helps any, and also get a resonator on it, ive read that maybe a cherrybomb glasspack can help quiet it down some, is that true, anyone have any ideas?

mlbbaseball · 02-08-2009, 10:48 PM

u basically need a resonator or 2, and you will be fine.

isaac_in_tx · 02-08-2009, 10:50 PM

how big of a resonator should i get? any recommended brands?

***norcalfocus01*** · 02-08-2009, 10:50 PM

yeah the glasspack/resinator will help. i had a straight pipe for a few weeks then had the glasspack put in and its now perfect.

***Mr.Bergner*** · 02-08-2009, 10:54 PM

mlbbaseball and norcalfocus01 are right.

Here's the one I got:

And here's the list of all of them. You can get the mid-pipe with a resonator, cat or straight pipe. Complete with a flange to the flex:

I got this off of Trubendz.com

I got one with the 14" Magnaflow in preparation for a header. After it warms up (6 miles) it gets real quite. Yet it sounds killer at about 3k RPM or 50mph hitting the highway.

Hope that's what you're looking for.

my car sounds like a freakin honda , its real bad, im gonna go to the muffler shop tomorrow and see whats up, i dont have to worry so much about the price cus the owner hooks me up.

illinipo · 02-08-2009, 11:26 PM

a high flow cat will cure the honda syndrome.

racerfan120 · 02-09-2009, 12:24 AM

^^ Really? I have read a high flow cat really does nothing? That would be awesome if it did, ha

illinipo · 02-09-2009, 12:25 AM

HUGE difference. Ask user mattellermets.

and if you get a good core it doesnt rob but maybe 1-2whp.

racerfan120 · 02-09-2009, 12:38 AM

Good as in magnaflow?

illinipo · 02-09-2009, 12:41 AM

im pretty sure the magnaflow "high flow" are ceramic core. if thats the case then no.

I would go for a metal matrix core, those give the best flow.

something like this (Thunderbolt is the brand RT uses for their cores)

How much differnce will the Magnaflow resonator make over an MBRP resonator?

On my SVT I have an ORP with the MBRP and it is pretty loud.
