ooo..looks nice. So it selling @ 109 per muffler? Personally i prefer a muffler with an oval body and an extended tip, but hey this looks good too.
thanks bro, the main reason i got it is because it comes with a silencer. Im also going to take out all of the resonators so when the silencer is out it will be loud as hell. when my dad comes home, i just pop the silencer back on and he will never know i took out the resonators:p

hmm.. how does it look with R1 Twin Mini Universal Muffler on each side? :D
:barf:

anyways, has anyone just replaced the mufflers? does replacing them really make a difference in sound:dunno: i know many people have axle back and cat back exhaust but what about those of you with just aftermarket mufflers:dunno:

my apexi dunks are really quiet. the mufflers were just put in the place of the stock ones. so i retain the stock piping. there's a low low rumble at idle but really imperceptible...at wide open throttle i believe the cold air intake is actually louder but then again i've never been outside of my car at WOT. I certainly believe that replacing the piping and removing the resonators will make the exhaust much louder.

hey BaddazTL, do u want your TL to sound loud or just loud enough to have people notice. cause a couple people i know have other exhaust on there tl and they say that their CAI is louder than there exhaust when they floor it. But is pretty quiet when drive regularly.:bigok:

I want it to be LOUD! I already removed my airbox resonator and put a hi-flo filter in so that increased sound slightly. I think when I take the mufflers to the shop to install them, I'm going to tell them to take out the resonators also.

jimster716: Do I have to replace all the piping? or can they just take out the resonators for increased sound?

does anyone have any idea on how much it will be to install my mufflers and remove the resonators:dunno:

for increased sound you can take out just the resonators and have the muffler shop just put a replacement sleeve.

If i was also looking for performance I honestly would have probably done a 2.5" pipe with 2.5" muffler inlets...but thats another matter altogether.

to remove the resonators and install the mufflers shouldn't cost more than $150 and that would be kind of high. But more importantly go to a shop that gives a rat's ass how the mufflers line up and make sure they test the correct look before they start welding everywhere. My guy put up both the mufflers on stands to align and check before he did any cutting and welding.

thanks for the advice :thumbsup: wow $150 seems kinda high, i was expecting like $70-$100. so if i tell the muffler guy i want the tips flush with the rear could he do it? how big is the outlet (where he welds the muffler on) on the stock mufflers?

The tips being flush is dependent upon how the guy installs it and the length of your muffler. The problem is that one side of the car the piping curves right where the stock muffler can is. As long as you have room to move then he should be able to put it wherever. Since the new mufflers are probably not going to be the same length nor the same height, he may have to be a little creative. The stock piping is about 2.25".

By the way, if the muffler guy has to use any of his own bent piping, tell him to use 2.5" piping...since it's most likely crush bent instead of mandrel bent, you want to use a larger diameter pipe to approximate the inner open diameter of the stock piping.

does adding just a muffler add any HP? or is just for show?
I think you have to look at it in reverse. The stock mufflers exist solely to suppress sound. The stock mufflers use chambers that rely on deflection to create noise canceling frequencies. An unwanted side effect is that some power is lost in this process of sound reduction. The TL also relies on b-pipe resonators to cancel out sound. It all has to do with chambers of air pressure to create noise canceling frequencies by deflection.

The advantage of many aftermarket performance mufflers is that they suppress sound strictly by absorption instead of power robbing deflection. Hence, the term straight-through design. You'll see in the performance muffler that there is a perforated tube that extends from one end of the muffler to the other. The performance muffler has sound absorbing material outside of the perforated tube within the muffler canister, usually fiberglass or steel wool mesh. The idea is to minimize backpressure and maximize performance efficiency.

This is a cutaway of the HKS Drager exhaust.


Now how well a performance aftermarket muffler works on a TL is circumspect because of the b-pipe resonators and, i believe, a relatively small piping diameter that the car comes with. In other words, if you want measurable power gains, I would go with a complete cat-back exhaust.

And who makes this for our cars? :dunno:
Greddy and A'PEXi offer complete cat-back systems for the 98 accord v6 which will fit the TL with minor hanger adjustment. Or another route would be to go with 80mm (2.5") inlet performance mufflers and have a muffler shop do complete cat-back pipe.:)

can i do a cat back with my comptech exhaust? Say have a shop do it? :dunno:
Sure you can...although really all you would have to have done is the removal of the resonators along the b-pipe.

Those b-pipe resonators exist solely for one reason...power robbing sound suppression...this is common for luxury cars whose ultimate goal is to create a silent passenger cabin.

One thing i need to add is that the "freer" your exhaust the greater the loss in torque is apparent especially in the midrange. There is an old adage that says that a little backpressure is good for torque which i believe was the concept of the Super Trapp mufflers that use attachable disks to adjust how much backpressure there is. Some exhaust manufacturers dispute this with dynos showing increases in both hp and torque with larger diameter piping and free-flow mufflers. I don't have the technical engineering knowledge to debate this nor do i have an in-garage dyno to test this. :D
