I admit I jumped with my response about getting rid of it just cause I was fired up about that stripped precat & a few other things. I am going to drill and tap that precat before I do any install of the exhaust. Bear with me for some video's as I work nights and weekends, have school and play a few sports during the week so I don't have a ton of time.

Yes they do offer a resonated version, however there is no option at checkout for it, I spoke to Mike directly and requested one be put on. It is an 18" so I don't think I'll have any noticible drone judging by what you non res guys say about it. Hopefully next week maybe monday I can get it installed and get some clips up.

 

I totally agree with you. I have said I was prepared that I would be too loud for what I'm looking for. The only way to know is to try it out and that's what I'm doing, as is everyone else. I explained in my last post my frustrations were from other things, not this exhaust's sound. But if it doesn't suit me then so be it, I'll move on to something else that's all, no big deal.

 

The Excelerate ones stick out a bit more. I didn't like it at first, but now I do. I don't think the look of round tips in a square cutout is that bad.

 

Its just that our cut outs are square, plus I have the RJ bumper so mine is even more of a pronounced square.

I agree, its not terrible but the ATLP tips are cleaner loooking.

 

Screw cleaner, I cant stop staring at them every time I walk up my car, so damn sexy

 

RV6 J-Pipe/Resonated test pipe combo, ATLP BASE and modified stock intake.

 

Looks good to me but, I can hear a certain individual now:

"Did you dyno before", or, "You need at least 12 consecutive pulls to really get a #", or, "That dyno typically adds 47 hp".

Hope my 5AT is close to that number with pre-cats, pulley, thermal spacers and about 100 lbs weight reduction.

 

100 lbs arent going to do anything for your dyno run


About the drone, as this thing breaks in, even the purr is reduced. I kinda forget about it until I get on the throttle.

 

Yeah, I was speaking more of dragstrip about the weight loss.

The break in is no joke. Sound has settled a bit and the engine has really come alive recently. Logged about 300 miles so far.

 

I'll see how mine will respond with a brand new aem v2.

 

agree 100%

 

You'll hear the V2 over ATLP at WOT.

 

How did you modify your stock intake? Do you plan on getting a cold air intake?

 

ONLY if I find a good deal. I'll find the thread and PM you.

 

dude, I floored it from about 20 yesterday and the girl spun so fast and growled so loud that I put a 2nd hand on the wheel to comfort myself.

I'm getting the backfire pop during wide open 1 --> 2 shifts!

 

Take it easy on her Ned haha. We don't want anything happen to you.

 

the pop will subside after break-in

PM'd you

 

I kinda knew it was something like that setup. It works the same way so i can see why you don't rush to get an intake. Makes it easier to clean the filter. Do you plan to s/c you ride? Can't imagine how it would sound with the ATLP exhaust.

 

we'll see in a year or so. I'm not doing anything until we have a tuning option.

 

Raj the actual ct mufflers and tips are rsonated as well, that is why it purs. I had a stock res and 2 aero's on my greddy and it still droned like a mother. Its the design of the muffler and I dont believe resonator will make a difference. You should have puicked up jnc's ct or just get some nice tips and your good.

 

You're right, that's why I think a mid muffler will. This is why I think Comptech added it. Also, I have the Stage 3 hack exhaust on my car right now, and once I removed the midmuffler and threw in the dynomax resonator, I have drone in my cabin too, not horrible drone, but nonetheless its there..so I'm convinced that the midmuffler is there to bring that down.

 

Sooo, climbed under the car to remove the heat shields above the rear muffler packs and anything else that felt loose. Heat shields came off and I decided to check all the bolts on the new setup, too.

La-da-di...what the? Shit!!! The y-pipe and long pipe connection had a visible gap in it. Closer inspection shows one bolt very loose and the other hanging in there but with no nut anymore. Well, that's not good.

Quick run to Pep Boys for washers, lock washers and a couple nuts. Don't know about you guys but this section of the Base didn't have washers and lock washers provided like the muffler pack sections. They did have washer-type nuts but I air ratcheted these plus a strong pull and they didn't hold. Also used loc-tite this time, which I should have done initially. I also started her up and checked all the flanges for air leaks.

OK, forget everything I've said about 'low RPM tinny sound and rattles'. Low RPM does resonate through cabin a bit, but there is zero rattle and it's a nice continuous growl now. Cruise RPM's are quieter, I guess like it should be. Not sure if engine responds better yet - raining bad for the test drive.

Did everybody else get only 4 sets of washers/lock washers? If your shit is buzzing and vibing bad at low RPM's, get under there and check all the flanges. Oh, those heat shields were the source of my rattling and can be taking off without removing mufflers.

 

Noob here

How do I get a hold of this great exhaust ??
Do I have to do any modification or just straight up plug in and play ??

 

www.heeltoeauto.com that is marcus's site and he is selling ATLP products. Oh, if you are in Canada i think it's 664 racing, www.664racing.com IIRC. Check on www.AcuraTLparts.com to confirm.

I don't know how much of a surplus there is but I bet it's only 2-3 if that many. No modifications needed. this is a plug and play made for our base tl's.

 

I didn't get any washers, just 6 nuts & 6 bolts. Hmm, I guess I'll have to go get some then.

 

damn, I still have a metal vibration under hard throttle in the low rpm range. Very hard to produce in Park/Neutral, which is making trouble shooting difficult. Definitely sounds like it's coming from the rear of the car but I know that this can be misleading from inside the cabin. Already aced the rear muffler heat shields, which definitely had the potential to rattle. There's one shield left recessed in a well about mid vehicle but it seemed very stable when I tapped around it.

Anybody successfully locate and isolate an exhaust rattle under the car? I'm starting to wonder if it's in the tips/muffler packs.

 

^^ I dont have a rattle :-/ But as you mentioned earlier I didnt get any washers either, may have to jack the car up today to make sure everything is still tight.

 

I may have reused the washer sets from the stockers. Can't remember. They all have washer/lock washer combos now and are holding well. I just fear my pre-cats or j-pipe is loose.

 

Located my rattle for all those that don't care. It's coming from the muffler's themselves. Not sure if it's in the can or where the dual outlets hit the tip. It's on both cans at around 2500 rpm with heavy to WOT. Currently talking to Mike about a solution.

Also, looks like Aero Exhaust is going out of business. Been trying to locate the AR 25 resonator all morning and most places are out of stock. Nothing in the Black Market, either. Might have found one in stock.

What are other decent resonators?

 

^^ I'd suggest getting a mid muffler if anything, sort of like the one that comptech uses.

 

Yes get the mid muffler, the resonated ones don't seem to improve much on any front from what most people post on here.

 

Is the Comptech mid muff straight through or is it chambered? Also it looks short maybe a 10"? I don't see anything wrong with using a 14" though. Did a little searching on jegs and there are a few that I think would fit. Magnaflow ultra flow, Hooker Aero chambered to name a few. I dont' think the chambered would kill much HP but would maybe boost TQ a little.

 

anybody got more pics of the base exhaust installed??

 

How does this sound for a stock TL without any type of air intake ??

 

Amazing.

 

those pipes are nice, and wont rust i like it.

 

sounds like excessive rasp, which ratlless. I had it with my greddy, got used tto it eventually.

 

*UPDATE*

installed Aero AR25 resonator. No mo' rattle. Toned down the note just a tad. I love it now. p.s. mine rattled because of pre-cat deletes, j-pipe and test pipe.

oh, I think Aero is going out of business. so, if you want this resonator better get on the hunt.

 

Does anybody in Charlotte, NC have one installed yet?? Would love to hear in person, really on the ropes about this.

 

Really if you are on the fence about this exhaust, you should go for it. I ordered mine, worried about it being to loud. But really, the tone is very nice and the drone isnt bad for me at all (i do have dynamat in my trunk and back seat though). I don't have a j-pipe or anything else either, so I think that helps keep the exhaust toned down as well. Overall, the gains are very noticeable and I have gotten a ton of complements
