Looking for suggestions on an exhaust to run on on my 2012 Chevy Cruze LS
Right now I’m running a 3inch catback exhuast with double back exits View attachment 300387

Do you have a turbo on that engine? A 3" exhaust is HUGE for a naturally aspirated 1.8L.

No turbo . What I’m running is a 3 inch pipe from the second cat back to where the rear wheels are . And a 2.5 inch pipe over the frame and out the back on both sides . I didn’t get a check engine or any loss of back force . & it sounds pretty darn good . I’m just looking to see if anybody is running any actual exhausts that sound gnarly lol

Gotcha. That makes sense as to why you didn't loose any torque you had. I actually have a Magnaflow Cat-back Exhaust that sounded good before I did all the engine modifications.

I'll PM you pictures if you'd like. It's just a single exhaust.

Yea I’d definitely be interested in seeing that, I also have a throttle controller , hit me up on Instagram @ohiomoddedcars

I don't do social media. I'll send you a message on the forum though.

Okay that’s fine too

back pressure, probably what my 1.8l is lacking... I have an exhaust leak after the second cat. makes the idle a little rough.

I don’t think I lost any back pressure, if anything I gained some

The stock exhaust is 2.25". If you go any bigger than that you back pressure decreases. Loosing some back pressure is ok, but if you loose too much you'll loose the scavenging effect on a naturally aspirated engine.
