I just want to know if a mid muffler does anything? besides making your exhaust louder right? and I just want to know if its possible to tune the TL?

 

It will only make your car louder. No significant MPG/HP.

I think there's an AEM product to tune our car, but it isn't really necessary if you aren't heavily modded (Forced Induction).

 

only need 2 tune for turbos and superchargers

 

you're not gonna notice any gains from just a midmuffler delete. you'll just notice that it drones around 2-3k rpms. yes its possible to tune the tl but why would you if you're stock? =/

 

suggestion on what straight pipes to use?

 

^the muffler shop will do that for you.

ask them to cut out the midmuffler and replace with a straight pipe.

 

go to Muffler shop pay 20-50 and they take care of it all.. tell them which one to remove and drive away after its done

 

acuradriver925, go there, do it, come back and enjoy it. it doesnt matter what pipe they use, they know how to do their job.

 

does it sound better in your opinions with or without the resonator? or no difference?

 

If there was no difference there would be no reason to do it. Its minimal but it is there.

 

I think I'm going to straight pipe it soon, because I just took my resonator out and it sounds like a whole new car.

 

the drone when straight piping is unbelievable. your passengers will hate you and you will get sick of it eventually.

i was straight piped for 6 months and then i grew up. i miss the noise sometimes but i know if i go back, ill just end up hating it again.

 

 

i took out the mid muffler and resonator and after i was done the check engine light came on and wont go off even if i reset the fuse... Whats goin on?!

 

theres no reason for your check engine to come on

get the code read with a scanner and then post it.

 

WErd, go to an auto store and get the code read for free, unless you're in cali

 

Does autozone do that?

 

that's a auto store isn't it and your not in cali right?

 

Yeahh im in ny.... I just never knew they did that my bad. Thanks for your help!

 

My guess is who ever did it let the exhaust fall either damaging the rear O2 sensor wiring or unplugging it.

 

ok so i went to autozone and the code was P0141 which is the O2 sensor.... is that something i can fix myself by getting under the car and plugging it back in or do i need professional help? Thanks again for all your help you guys are the best!

 

fsttyms1 called it

 

it would be easier to go back to the shop that did the modification and get it on their lift. make them do it.

 

But its simple right? Like any mechanic should be able to do it? Cause the muffler shop i went to takes forever to do anything....

 

well assuming that it was just a sensor knocked loose, then yeah it should be a simple fix. but we dont know if they broke something.

 

Replacing the O2 sensor should be on them. It's not difficult at all.

 

Ok yeah... And thanks again guys for all your help!!
