Been trying to figure out what setup to do on my 08 TL-S for a while now. Have heard quite a few nasty sounding setups that have a lot of rasp. But I believe I found what I want that sounds amazing. I just want to verify what I need the exhaust shop to do. I provided a generic picture of a stock TL-S exhaust.



So they need to remove the resonator and add the Dynomax as shown in place. Then Cut that big fat "mid muffler" And just add a 2.5'' straight pipe correct?

thanks guys!

Yes, it's also known as stage 3 mod. If I were you, I would start with stage 1 first which is deleting the mid muffler with straight pipe, then if you want it more louder, do stage 2 (mid muffler delete, replace stock resonator with magnaflow resonator) or stage 3 (mid muffler delete, replace stock resonator with dynomax resonator).

^Sounds amazing

Learn something new everyday, thanks!
Never knew it was called the "Stage 3 mod" That is silly. I am not going to spend more money going in increments. Going to do it once and be done. If I don't like it I will replace it with the magnaflow. But based on the videos I have seen like the one above I am sure I will love it. A bit of drone on the highway is fine with me.

Kevin17112

I think that's with rear mufflers deleted as well. Sounds a bit too loud IMO, but if you like it, go for it.

4drturbo

I need to learn how to read. Yeah I see its "rear delete"

Here we go


So I have to decide if I want to the exhaust shop to delete the rear mufflers or just leave them stock.

Kevin17112

You can tell them to just remove the mid muffler, you can also show them when they jack up your car just to be clear.

I did this whole "stage" mod to my TL-S, I went straight to stage 3 with same res a few months ago and I regret nothing lol. I didn't delete the rear mufflers though like that video. Now I don't hear my car drive by me very often, but its pretty quiet at cruising speeds in the cabin. Even highway cruising at 80 I don't notice drone, but I have my radio turned up moderately loud most of the time. I say go for it when you step on it, it definitely opens up and gives you a nice tone. Also, I would keep the rear mufflers on, let the res break in for a couple weeks and if it's still too quiet for you, straight piping those could be an easy thing to fix in the future.

Only thing I would be a little worried about is if you start deleting cats and changing jpipe, things like that and you might introduce rasp from what I've read

I do have a video of WOT driving by shot on my iPhone if you're interested or want more sound clips lol but my friend didn't quite time the drive by perfectly with the shifts

4drturbo

Thanks for the offer of the videos. Sounds like it will sound good. Yeah I don't plan on doing a jpipe or deleting the cats. I don't want my car to sound like crap to free up a couple horsepower on a 3600lb luxury car. I will just have them do what I originally stated in post number 1. Will get a before and after video.

thanks guys!

Took it to this awesome muffler shop about 30 minutes away. Got quoted @ $60. He asked why not just straight pipe the resonator instead of adding the Dynomax. Good question. Anyone do that? I assume it would be louder but would that add rasp and sound like ass?

Kevin17112

Not that I know of, I'm curious to find out what it sounds like, I'm guessing pretty loud.

I believe it would add rasp/drone to the exhaust. Stay with the resonator.

I uploaded this video just for the purpose of this thread so ignore the unedited bs at the beginning and end. This is my 06MT tl with stage 3 exhaust mod. Not the best quality but you may get the idea. It is barely noticeable at 75 on the highway. Still drive it whenever need be on long trips. I personally really enjoy it and it never gets annoying at all in the car on normal commute.
Feel free to ask any questions. I'm not going to respond with "use the search feature."

Rasp. Sounds pretty awful at part throttle between 3000-4000 especially.

That's what I did after the J-pipe (already deleted the mid-muffler). Shop suggested just removing it and replacing it with a straight pipe. I was back within a week having them add a Dynomax resonator. Completely eliminated the rasp. Car has a throaty idle, sounds good when you get on it, can't even hear the engine from inside my car at freeway speeds.

Ignore the overactive traction control at the start, forgot to turn it off.

4drturbo

^You did the "S3 mod" after the Jpipe? Well that makes sense. I am sure the free flowing Jpipe will add a ton of rasp with a straight pipe right after it.

But yeah I am sticking to my plan and having the dynomax installed.

MyGuti

total newb with this stuff, but I am also contemplating the stage 3 mod for my base TL.
Where can we purchase the dynomax resonator? What is resonator's model number ?

Thanks

Kevin17112

Dynomax 24215

I bought mine from amazon for like 40 bucks or something.

Here is a video as promised. Please note it was VERY windy out. Wind drains out the noise a bit when picking up audio on my phone. Plus it was filmed about 20 feet away


Car sounds stock cruising around. No drone, no noise really. But give it a bit of throttle and its a louder then stock in a good way. But nothing crazy. I honestly thought it would be louder based on the comments in here. This is the perfect mod for me because it is not loud but it does add a bit of exhaust noise at wide open throttle and little bit of rumble at idle. Next step would be to delete the rear mufflers. But the exhaust guy said it will be pricey to do that due to needing to add a Y pipe to each side and leveling the exhaust tips and all.

Greg is a wizard @ Rose's Muffler. Knocked it out in about 20 minutes.

Sounds good. Deleting rears will sound pretty loud and ricey IMO and you will lose some low end torque due to no back pressure.

treal512

Sounds good indeed

I wish I had gone with the 12" res, but the 18" is nice too.

4drturbo

I take it it is even more quiet with the 18''? I went with the 12'' due to YouTube videos haha. My setup is quiet. Sounds great, no rasp or anything crazy. Just an aggressive tone over stock.

treal512

I haven't heard a comparison between the two, but I am assuming it's a little quieter than yours due to the longer resonator chamber.

Either way I love it. I think the people I drive by like it too. Thinking about a CAI now to get more throttle feedback for better shifting (6MT).

MyGuti

I picked up my resonator and will be getting the stage 3 done in the next few days! Cannot wait

Kevin17112

A CAI will definitely make it sound throaty, I have Injen CAI on mine and it sounds great. Power wise, it does pull a little harder but then again some people won't notice the little gain it makes.

MyGuti

I thought I was going to wait before adding this to my newly acquired 6mt type s. But every time I hear the base start up, I want the same sound for my 6mt lol.
Just wanted to confirm that this will fit 6mt type-s models as well, Im pretty sure the mufflers are the same?

Steven Kenzou

Why do people recommend the stage 1 it really doesn't make a difference deleting the mid muffler. Stage 3 sounds aggressive and loud but it really isn't until you get up to around 4k and even then it's pretty quiet.

MyGuti

comes down to what you consider "loud"
On my base, the difference is at 2.5 to 3k rpm, and its enough for me to hear it in the cabin (without music).
I am yet to hear it as a bystander, but it is enough for me.

Now with my 6mt, I will be able to hear it much more and its a manual and I dictate when to shift...

Scottwax

It's cheap and it's just a first step. Some do the delete and resonator swap at the same time.

And keeping the car quiet inside (especially at freeway speeds) is a must. Ended up changing the muffler on my G35s exhaust because of the drone at 2500 rpm.

kygenbagels

Do you remember what part number that dynomax resonator is? I know that sometimes in the stage 3 mods, people use 3 different types of dynomax resonators.

twokexlv6coupe

Please excuse my ignorance, but why is the difference between Stage 2 and 3 simply a different brand of resonators? Is it a matter of baffled vs straight-thru? Seems like a very mundane detail to jump from stage 2 to 3.

In the STi world for reference, Stage 2 would be a turbo-back exhaust (any manufacturer), and Stage 3 is a turbo-back plus headers and up-pipe (again any brand) for instance
