Not happy with exhaust sound
 

orla

Yeah you basically did the UPS truck exhaust mod to your Z lol. Sorry.

The good news is that since you're already thinking about it, might as well do long tubes. That will IMPROVE the sound quality substantially. And you'll pick up power too. (and more power if you tune the car)

Not sure why the front cat delete is even an option. Because if you're doing that you might as well do long tubes.

My car just with the borla xpipe in track mode sounds incredible. That's how it was supposed to sound from factory. I would do long tubes but i'm waiting for the C8 so i can upgrade anyway.

Held hostage by the worry of losing warranty you likely will never use when the big 3 (intake ,2300, headers. really propel the car doubling the fun.

Your first mistake.

Video?

Long tubes plus Corsa equals super sound!

Yea going to have to ditch the cat deletes. Longtubes will make it sound amazing.

If you're considering dropping $4K on a catback for pure sound. You shouldn't have much concern over warranties. You could buy a new built shortblock for that. :lol:

This is the first thread that I have read bad things about the norcal cat deletes, am I missing something? I was planning on doing the cat deletes with borla x pipe now I am second guessing.

Its

Yeah don't.

If you can't do long tubes, leave it alone.

Or to the very least, install that borla. It will actually sound like it has long tubes (seriously).

The xpipe really opened the sound of these cars. You think it sounds good stock, wait until you put the xpipe. Same good sound, just louder and more "raw".

Don't do the front cat delete unless you're doing long tubes. Let this thread be a lesson to all thinking about it.

The problem is matching an inferior product to the Borla.

Better go back to stock if your so worried about the warranty which the cat delete will kill if the dealer sees it! Cat removal on headers amounts to a couple hp!

Any chance you could post a video? The only video I have ever seen was the video from the manufacturer.

Maybe I'll just start with the xpipe and go from there. I want my car loud, but I don't want it to sound like crap. Maybe a borla catback with borla x pipe will sound better than the borla xpipe/cat delete.

You don't need the borla catback, the factory NPP exhaust is AMAZING for what it is.

Trust me all you need is the xpipe. I wish i was local to you so i can show you. It's really all you need.

Loud when you want it (in track) and still dead silent when you need it (stealth).

I'll start with just the x pipe, I appreciate the feedback. I really want my car to be obnoxiously loud, that's why I feel the x pipe wont be enough. But ill start with that and see how it sounds :cheers:

Why? Do you enjoy pizzing people off? I got past that when I was in my early 20's. How old are you?
A high noise level won't make people think you go fast, anymore. Some of the loudest bikes are Harleys, and some of the loudest cars running around on the street are stock economy Hondas with fart cans. Neither is fast.
