I installed a GReddy SP catback exhaust on my car w/ random technology high flow cat, and a place racing cold air intake, how come i hear no sound out of the exhaust?

 

Try starting the engine......... j/k

Intake sound overpowering the exhaust?

 

any catback exhaust is relatively quiet as long as its not a round ricey muffler. get a y-pipe and you'll be pleased. my greddy is plenty loud... maybe its just cuz people have different preferences

 

yea the intake is loud, but i still get nothing out of the exhaust, i will be getting headers and a ypipe soon hopefully so that might free up the air flow

 

that will definitely be LOUD if you get a y-pipe and headers

 

this is interesting...i like the way mine sounds right now but i was considering getting greddy.... follow up after you get headers....interested in the sound of headers/greddy

 

When I put my SP2 on it was quiet I only heard it under like 2500 RPM's after that it was all my engine and I didn't have an intake at the time. Now with the intake, Y-Pipe, and SP2 it is loud but deep. I like it most of the time.

 

get a y pipe..

 

im soon to get an unresonated b-pipe with a hollowed out custom muffler... i like it loud

--but yea, a y pipe will solve your problem

 

That way up in CT I'll hear you too.

 

Trust me, you should be happy you don't get too much sound out of it. If you go with Y-pipe it will be louder. However, PLEASE DON'T get rid of the resonator. My car is witout resonator 2.5" Piping and Y with a magnaflow exhaust. I'm going to install a resonator when the weather clears up a bit.......

 

Yeah I agree get a Y pipe.

 

dude jooo need to turn up your volume so u can hear the damn exhaust better


on a serious note. when exactly dont u hear a sound? high rpm's? idle? start up? we need more info

 

y-pipe is your friend! I couldn't hear my OBX cat-back until the y-pipe went on.

 

seriously? so by saying you cant hear it, you mean the very quiet like stock until you rev above a certain rpm then you hear it more, or you still have a stock sound till that Y gets on?

 

i dont hear anything from the exhaust starting from the turning of the key to driving at highway speeds, but im thinking its because i need to finish up the upper half of system and get a y-pipe and headers

 

never knew the Y-Pipe had such a large affect of the exhaust sound. Intersting. . .

 

seriously...all my friends used to laugh at me because my car was so quiet. Once I put the y-pipe on, they were all like "finally, you got an exhaust!".

 

Friend has a Maxima as well and all he has for exhaust are Y-Pipe and B-Pipe with some kinda aftermarket muffler, that shlts loud at 4k+ rpms
I'd rather have no noise and performance than loud freakin noise and performance.
This is the reason why I might just keep stock muffler with Y/B-Pipes.

 

Actually after doing a couple weeks' work of research I found out the stock exhaust manifold is good enough for performance.

 

I'm the opposite I'm tired of the loud noise coming out of the y-pipe, I have the stillen y-pipe. I'm going back to stock or get another type of y-pipe. Trust me you want a quiet exhaust. It gets very annoying after a while.

 

not only that Broward county police are ******, when they hear a loud muffler they'll ride that person's *** just to scare the drivers.

 

I have cattman headers, Greddy SP2, and and Magnaflow MS cat. I was worried it would be to loud with what i have read, but accually it is still quiet. You can hear the exhaust but it is never loud. I am the type of person who does not want to draw a lot of attension to their car and my setup does not. I have recieved nothing but compliments. I compaired my car side by side with a 350z about 2 months after installing the exhaust setup. I would say the Z was just a bit quieter, but not much, also you could hear a very small bit of difference in tone, the Z was a little deeper sounding. In my experience my setup is much quieter than a civic with mugan headers, Random cat and Greddy Evo, quieter than a stock 3000GT, and quieter than any car with a cheap autozone muffler.
