Exhausted Opinions
 

What do you fuckers prefer when it comes to making a cheap exhaust. I'm gonna do a 2.5" all the way back from the downpipe (read: when I get my turbo kit) but what do you guys suggest as far as a muffler goes? Something cheap but doesn't sound like ----. :6


Oh yeah I've been told that turbos cancel out noise... If this is true does that mean the exhaust noise won't sound like a hive of angry metallic bees coming out of my ass anymore?

Turbos do quiet the exhaust. I had a glass pack and thrush muffler on my hatch with a header, and the put the turbo on and it quited down a lot.

turbos help get rid of the raspy sound. i just made a 2.5" exhaust out of an intercooler kit from racing solutions. it is 2.5" from the turbo to the muffler with no cats or resinator. i used a $20 stainless ebay muffler and i think it sounds awesome.

Get a sound clip of that ----...

Re: Exhausted Opinions
 

2.5 straight pipe with a blown rez and a glass back
no rasp, sounds great and is quit till waste gate opens up

Re: Exhausted Opinions
 

Nice ;D

Looks like an exhaust is going to be cheaper than I thought.

Re: Exhausted Opinions
 

3" is way overkill. im not saying there is anything wrong with it, but it is overkill on pretty much anything built on this site

Re: Exhausted Opinions
 

may be true, however, the 2.5" system has a cross sectional area of 3.91761 square inches; a 3" is 7.069 Sq"...80% larger.

while it certain may be more than you need, there's no way it will hurt you, and I'd suspect you'd see better spool/ouput all other things being equal.


but yes, to answer the first question, the turbo acts as a muffler, wire your wastegate open and you'll notice the difference right away. a 2.5" system with a muffler alone will not be loud. Make sure to get a straight-through designed muffler to prevent flow restrictions/loss.

fwiw, my 3" exhaust with a small magnaflow muffler is much quiter than the same engine with a header, 2.25" exhaust with an additional resonator and larger muffler.
