I'm still new to the whole car modding thing and I don't know a ton yet, but I'm trying lol. I have an 05 TL and my only performance mod so far is a Injen CAI and now I am looking at modding the exhaust. From what I've read I think that I want the ATLP J-Pipe and Race Pipe for now. Later I'm planning to get the ATLP quads and a Type-s back bumper so it'll fit.

I'm close to making a final decision on these, but before I do I need to know if these mods are going to delete any of the cats. If they do, will it make a big enough impact on the emissions so that I fail? I live in Maryland if that helps any.

Thanks I appreciate the help.

 

dont think they make the quads anymore. atlp is a great exaust. i have there full set up

 

is it just the base then and i wont have to get the bumper? but do you have any idea on the cat question?


thanks for the quick response too

 

the race pipe will delete your third cat. But mikes race pipe has bolt holes to mount your heat shield to it. IT is clever in hiding the race pipe. Looks like at cat with the shield around it. that will help you pass the visual inspection It wont make it throw a cel either.

 

possible noob or dumb question but what is a cel? and do you think it will make that big of a difference in the emissions testing? if i remember correctly i think i read somewhere it isnt a big difference. but you definitely suggest getting the race pipe correct?

 

yea get it,you dont need that third cat. CEL is check engine light.
me and other people here had no problems passing emissions.

 

alright thanks man you were a huge help. i think im going to order the j-pipe and race pipe tomorrow or monday. install is easy as well right?


and im assuming the added power is noticeable and makes it a worthy investment ?

 

yep,comes with gaskets as well. you will get alittle bottlenecking until you get the atlp base exaust. remember the j-pipe and race pipe are 2.5 inches. that will go into your stock exaust which is only 2.0 inches. (i think) you wont feel full power gains until u have all the pieces to the puzzle. Be patient grasshopper.

 

gotcha. thanks again for the help and quick responses sensei. hopefully the base will be soon to follow

 

no problem

 

They still make the quads, I just got mine.

 

I thought so but I wasn't sure if I was just making a mistake. I believe I saw them on heeltoe

 

Anyone try the TSUDO catback system? it's more cost friendly and seems pretty damn good but i want to know the gains!

 

the gains from most aftermarket exhaust is almost the same... all of them are 2.5 till the 2.25 y pipe .. the tone is what people are goin for..

 

just installed my ATLP V2 and absolutely love it... it was well worth the LONG wait!

 

why not just purchase the TSUDO and save your money. It has 2.25 piping...y pipe all of that, then add a j pipe and your good!

 

i think the RV6 puts up more gains than anything. its a true dual system which was built to be used with the RV6 j-pipe to produce the greatest gains. the sound comes second in that system i think

 

 

get the atlp,i saw another member selling a quad set up for $1000
if he came down on price it might be worth it

 

im going to be deciding what im getting and when tomorrow night. at this point im definitely leaning towards the ATLP.

 

As soon as you add the exhaust, you'll def. notice a change in the mid-high range. Car should pull really well above 4,500RPM compared to stock.

 

is it a good idea to have the rev limiter removed? not trying to change the subject but the last comment made me wonder. and do you get any rasp rick with the RV6 j-pipe, race pipe and the ATLP exhaust considering they arent the same brand? or does that have nothing to do with it?

 

no reason to mess with that^

 

im just curious

 

I still feel that the TSUDO system is worth it. I am sure the ATLP system and others are great but you paying for the same thing. At the end of the day the systems are just 2.25inch piping and mufflers, what makes it worth $1200?

 

I may have some, but I honestly don't pay attention to it. Love the sound too much.
Why buy TSUDO, when you can get the same thing from a custom shop for $500, or so according to another member.

 

does the j pipe (atlp) actually make the oem exhaust or after market exhaust louder?

does it actually produce more horsepower gains not only dynoed but that you can feel?

 

I am buying the tsudo exhaust I will let you guys know how it is.

 

gives aftermarket exhaust a nicer tone. yes you can feel alittle difference.
wont notice powergain with oem exhaust. bottlenecking will occur and u will lose torque.

 

ordering mine now from heeltoe

 

Exhaust or j-pipe?

 

Both!

 

where can u buy atlp exhaust or j pipe??? new to this site....

 

heeltoeauto.com is where i went to order mine

 

you wont regret it,how come u dont have any pics of your ride?^

 

what about the race pipe? if you can, do it all at once

 

I got the ATLP J-Pipe, Race Pipe and Base Exhaust

 

And my TL is just Basically all stock looking from the outside so I didnt think it was worth uploading pictures like that lol

 

:gheywave:Im so excited!!

 

Good choice. ATLP base & quads are essentially the same at heart, just different tips & I think the quad is just slightly louder at WOT.
