That whole exhaust note through the speakers thing is annoying as hell i'm so happy I didn't get the premium system.

You answered it, I don't have the GM performance exhaust so it doesn't apply to me.
Thanks for your concern.

I leave mine switched off, I never really noticed a difference.

I'm curious, how did you turn yours off? I didn't see it in the menu system unless it's part of the "auto-volume" but I thought that was similar to "speed compensation" feature you see in other cars.

I disagree with some of the others as well. I've upgraded the exhaust on 4-cylinders in the past and they've sound fine. I typically prefer Magnaflows/Borla (same design, but Magnaflow is cheaper) over Flowmaster as the Magnaflows have a deeper, mellow sound over Flowmaster's more treble, raspy sound. To each their own.

My car is leased and an auto so I'm not sure if I'm going to mess with the exhaust. I like to hear turbo spool over the exhaust, but that's just me

Thanks but not seeing AXLE back!

Sorry, if this a dumb question.

Will installing a catback system cause Check Engine Light ?

I received my S-type axle back system today and will be installing during the weekend. Giving a second thought if I can order a y pipe and make mine a full catback system.

Also, I was browsing the mid Y pipe in Phastek performance site. It says that pipe is only for racing cars and not for street or highway driving.

This is the one. Am I looking at the right one ?

My car is a 988 miles now and this will be a great 1000 mile mod :-)

A cat back or axle back typically shouldn't cause a Check Engine light. However, double check your stock exhaust, because I think there is an additional resonator in the stock exhaust that is eliminated with the linked Borla product you've listed. The whole 'not for street use' is just an ass covering measure for them so they don't get fined by the EPA. If you live in a state with an annual inspection or emission inspection, you might want to double check that the exhaust won't cause you to fail a visual inspection. I like the 3" section of the exhaust, but don't like that it necks down to 2.25". Full 3" would be much more advantageous.

Most of those emission laws don't pertain to the resonators but the need for a muffler of some type on the exhaust system. No catback or axle-back should ever throw a CEL unless it's installed incorrectly.

Shameless non-self promotion but I would also suggest calling a few muffler shops in the area. Buying an axleback system is pointless in my opinion. Near as I can tell you're going to need to cut and clamp to get the stock muffler off anyways. So there's zero benefit to buying a system when a shop can cut off your stock muffler, slap on some aftermarket mufflers, *weld* your pipes, and align your tips to your liking. You're also supporting a local business and keeping money in the local economy.

Alright, I'll get off my Austinite soapbox now
