I was looking through the options GM has for performance parts and the cat back upgrade they sell looks pretty nice but it is priced at about $1000, has anyone tried the oem performance parts and if so what are your thoughts on them? thanks in advance.

I just built my own. The OEM exhaust is non restrictive so any exhaust upgrades are for looks and sound

well i live in a state without emissions testing so whats your idea on removing the cat and reducing restrictions that way. i am going for sound a bit tbh because i do want the turbo a little louder.

I live in MN, no emissions testing here either. Exhaust doesn’t really increase turbo sound, that’s mostly intake. The OEM cats are high flow I believe to increase fuel economy, so you won’t really gain outflow by deleting. But experimenting with it to find a sound you like is always good. I love the way mine sounds, it growls, and turns a lot of heads

Catless downpipe to downstream OEM cat, OEM resonator, that goes into a glass pack, then splits into a dual exhaust exit, whipped it up myself.

I grabbed the GM Performance Exhaust and GM Performance Brakes from the dealer..

The exhaust has a good medium growl and the Performance brakes were completely worth it..

The brakes are super smooth and powerful

I was looking at the breaks too, are they more pistons than stock calipers or just stronger? i know the rotors are better, been really wanting drilled and/or slotted rotors

Man, super jealous on both items! The brake setup looks very nice indeed.

And scrubby there is power to be had w an aftermarket exhaust. Mandrel bends and a better flowing muffler do make a difference even if it is small.

They are vented and slotted. They are also larger than the stock rotors and prevent almost 100 percent of any slight vibration...

I was told by a buddy who has a 650 horsepower bonneville to avoid cross drilled rotors as they need to be hot before they get very grabby and they tend to be in the brittle side

Duralife rotors have great ratings and reviews across the board. I'm no expert but so far these GM performance brakes are worth every penny.

I'm interested in learning more about the brakes. Can't seem to find any Cruze Performance Parts online at GM Performance Parts.

Anyone have a link ?

That's good advice from your friend. Generally speaking drilling or slotting your rotors does more harm than good. It tends to be an aesthetic thing more than anything else due to the tuner market.

Look at a race car. They tend to be solid discs with vents on the edge for the most amount of surface area contact possible. Plus you avoid things like warping, cracking, scratches, etc.

That said this GM kit looks nice because the slots are minor and if it's larger disc and better calipers that's going to offset any damage you could possibly do in a daily driver compact car.
