i have a cattman catback and it makes a ticking sound...when driving/parked after driving..pretty much when the car is warm...its a loud tick or clank...sounds like its coming from the resonator..anyone have this problem?...it ticks every 1 or 2 minutes...something like that......Also...when going around a tight turn and hitting the gas..the exhaust makes a wierd grumbling sound..anyone else have this?

 

I have a 2k1 with Cattman Y-Pipe & mid-pipe + powertech muffler, the mid pipe knock on the cross member and the muffler section knock on the top of the rear axel beam, I though of removing it but there must be a reason why it's there... As for the muffler I'm going to buy a Cattman and get rid of the PowerTech. I'm shure Cattman did his homework and hopefully the knocking will stop.

Cheers

could you use some exhaust wrap around the knockin parts?

 

Mine is fine !!!!!

Cattman from end to end. No knocking, no banging and no clanking....

That's not going to solve the issue.

joeyd - Often times when guys install aftermarket exhaust, there tends to be a slight rubbing / vibration against a small cross beam near the cat.

 

my 2001 i30 is completely stock, and it also make a grumbling sound when making tight turns sometimes. this noise only occurs immedietly after i start the car, and only happens during my first tight turn. i have no i dea what it could be

 

YO I HAVE THE EXACT SAME PROBLEM AS YOU! Damn I thought I was the only one too....and i was kinda embarassed to post about this problem becuz it sounds so dumb ...see the thing is....even like 5 minutes after I turn off my car...theres a ticking noise every 10 seconds.....and nobody can say "oh its rubbing/banging against something" becuz the car is turned off and nothing is moving...the ticking noise is loud too btw....I could hear it from like 50ft away if theres no other distractions around me.....oh yeah its coming from the end of the bpipe....nowhere near the resonator.....so what do you think it is? Cattman should step in and answer the questions....

 

lots of cars make that noise after you drive them....even stock. i am not sure what it is, but i doubt its anything to worry about. could just be the exhaust cooling down?

 

I have driven many cars, and none of them make the noise that my cattman c-back is making after turning it off.....From accords to camrys....to TL-S to Maximas....none of them make that ticking noise....or maybe they do but NOWHERE near as loud as my 2k2 maxima with cattman c-back....so I dunno whats up....and i'm pretty darn sure its not the car's fault either......becuz if another member with the exact same catback is experiencing the same noise....then it must be the exhaust....

 

mine does the same thing.
It's nothing, don't worry man.

 

Mjg - are you stock? or do u have the cattman bpipe or muffler?

 

It's the sound of the metal reacting to the change in temperature.

 

Thats what it is, ever since it has gotten cooler down here in Fl ,after start ups duing anytime of day , my exhaust will make a slight rubbing sound for the first 5 minutes, which is basiaclly the warm up time for my engine, after that, its fine.

 

my camry used to make a ticking sound after it was turned off.

 

Yeah, that's probably it, or its just cooling off or something... my stock cat-back used to do that too....

 

Well how loud is that ticking sound of yours? Because NO car i have ever driven made such a loud ticking noise than my 2k2 Max with cattmang exhaust.....Literally you could hear it 100ft away.....thats how loud mine is....my stock Catback didn't make this noise what so ever....what gives?

 

I thought you said 50ft

 

That is what im talking about...even when im driving the car..you could hear it, when the radio is off...my old car used to tick after i shut it off for a while..but this is loud...

 

yeah i did say 50ft too....but now that i think about it....i'm pretty damn sure i can still hear it 100ft away.....yes its that loud.....basically its as loud as someone's brakes being worn out....u guys heard of cars that have squeaky brakes right? well u know that they can be heard from far away too right? same thing with this big TICK every 10 seconds.....yes its that loud..

 

ITS NORMAL !! i had the same thing on my 99 camry, 96 corolla, 94 sentra... havent noticed it on the max yet but i know i soon will. nothing to worry about its normal.

 

A we are talking about our aftermarket cattman exhaust..not our stock exhaust.....B did your cars make a loud clank while driving under normal conditions...i dont think so..and i know it is not normal...it is normal for your exhaust to click after you turn your car off and it is cooling down......im sure its probably happening because of heat but it is not a normal condition...for me and the other guy that is having this problem...what do you think we should do?...where'd you get your exhaust from?

 

we shall see

 

your talking about a ticking...almost like a pinging sound or something right? my sentra used to make it with stock exhaust, my moms impala makes it with stock exhaust, my max made it with stock exhaust and now the cattman does it. you can hear it from under the car after you park it go ping, ping, ping for a while.

atleast i think thats what your talking about

 

Lytheum - Yes its a pinging noise....but let me tell you....its NOWHERE near stock noise.....yes I have heard stock cars that ping from the exhaust after u turn it off....but this is a VERY LOUD ping.....it can be heard from over 100ft away.....its starting to bug becuz today I was sitting there at the drive thru with the car turned off (long drive thru line) and everybody kept starring at my cuz it kept on pinging even with the motor off....sounds pretty stupid but I aint the only one with this problem....

JoeyD - I bought mine from Cattman directly...where did you buy yours? If this problem doesn't go away within a week or so...I'm going to give cattman a call.....

And to the rest of you folks....THIS IS NOT NORMAL!!! trust me on this one you guys....I bet you think the pinging noise is very quiet and minimal....no it's not....its VERY LOUD....way louder than a stock exhaust after you turn it off....and its coming from the BPIPE area....not the muffler.....oh yeah towards the end of the bpipe not the beginning.....like where bpipe "bend" is...

 

Oh yeah forgot to mention....it pings continuously every 10 seconds....until maybe 10 minutes or so.......so it goes PING!!!!!! ten seconds.....PING!!!!!!!!!!!!!......ten seconds......

until 10 minutes later or so......its a very loud ping too....very strange exhaust imo

 

I'll buy your exhaust from you, and you can be rid of that pesky ping... 10 dolla

 

steven88..let me know when you want to call them.

 

I'm going to wait for a week.....just got back from school and I can hear the ticking noise all the way from here.....car is parked inside my garage with my door shut...and me sitting next to my computer 1 room down.....

 

20 dollars

 

i dont have one there garbage

 

what exactly are you talking about icepick?

 

Its the metal cooling down. Maybe its louder than stock only because it is made out of better material than stock. Or maybe because it is larger than stock. I have ypipe and cattman catback and I have heard it before . Try listening for something when you have a v1 screaming in you ear!
I also took that cross section out that causes lot s of vibration from the exhuast sitting on it.

 

so if the noise is because the exhaust is made of a different material than stock, we can assume that there really is not any problem at all?

 

If everyone is hearing the same thing than it sounds like a normal thing to me. I think that would make the most sense, dont you ?

 

If its the metal cooling down....then can you explain to me why I can still hear it with the car turned on? Even after heavy city driving with WOT runs here and there....It still pings

 

just because everyone hears the noise does NOT make it normal.

 

im telling you man there crap
