i have 3" piping that leads to a 4.5" muffler. I still have my cat and resonators. but it is still loud as F*ck. honestly its the loudest car in my school/neighborhood by FAR. basicly its the loudest car ive ever heard. people thing i have no cat. anyways, back to the issue, wat can be a nice quiet tone exhaust when im cruising, but still has that nice sport tone when i gun it? any suggestions?

i was thinking of the itr exhaust, is that any good?

 

rsr exmag

 

ITR is GOOD... but for almost the same price you could get a WS2 or rsr exmag. They're generally regarded as the two quietest exhausts besides OEM

 

A twin-loop is another option.

 

the trick is not to get a "straight through" design muffler. that's what makes them so loud. apexi's world sports 2 is an extremely quiet exhaust.

 

are you running a turbo?

 

The noisy thing bout your exhaust maybe the result of poor air circulation of and its would also depend on the design of muffler on your car and the K & N cold air intake.

 

a 3" exhaust is a little overkill unless you are running a turbo.......but the exhaust suggusted are good...been thinking about doing this myself...right now I have no cat....omni test pipe with oem itr b-pipe to a HKS ....its a little loud but not god awful ricey....

 

I'm assuming you are turbo'd since you have a 3" exhaust. A chambered muffler like the ws2 will be a HUGE bottleneck. There is absolutely no reason to get one. A good middle ground muffler is the Vibrant flat black muffler or ES Oval which utilizes a straight through design but is much quieter than your average N1 muffler.

Now if your stock NA than your exhaust (straight through or chambered) is reduced to a noise maker. If you are going to start doing headwork to your car than you benefit from a straight through design opposed to chambered. If not, stick with a chambered muffler.

 

look into the MagnaFlow 14828 muffler....i'm using it on my new exhaust....its a 3" straight through, but on my buddy's 240, its nice and quiet on 3"
