Lightest Cat back exhaust

Planning on getting a cat back exhaust (need to keep my warranty for now) and since the car is set for road course use/autox, Id like any feedback on which cat-back exhaust system is the lightest.

I understand I prolly will not gain much if any HP/TQ but obv. the most gain will be a nice treat as well.

Please let me know any experience you may have. I look to have something ordered early next week.

The only one I know is Borla-ATAK cat back which claims to be 43lbs lighter than stock.

FYI- only a cat back exhaust, no headers or high flow cats unfortunately


Bassani?
ARH?
KOOKS?
Flowmaster?

Thanks!

Loudmouth = muffler delete = best gain and lightest weight. Also is loud as hell

Yep, what Chase posted. The lightest you are going to get is just straight pipe. No cats, no mufflers, no resonators, Just pipe.

The best part is that is sounds sick.

And here it is with headers.

If you buy just the cat back it will bolt up to your factory mid-pipe/cats.

If you buy the headers you'll have the option to buy an off-road (no cats) or a set of HF cats and you'll dump the factory cats. The cat-back would then bolt up to either the off-road pipe of HF cats that you buy.


Also, just as a side note.....have you ever felt the air compressor that's in the trunk. The one that goes where a spare tire would be? When I felt that (knowing I would probably never use it) I pulled it out of the trunk immediately. Just saying....if you're trying to loose some weight.

yeah man, Its out! 5.2 lbs lost along with the child restraint 4.6 and then I have 15.2lbs so far lost in the front. Not much yet and its all I can do for now before the event this Sat.

I need to research stainless works and see what people think... The price is spot on considering I have been looking at Zoomers and Borla for around 1500... Im not sure how the quality compares though and I know Borla claims a 43lb weight reduction.

The system in the video includes high flow cats. It is legal.

Stainless Works quality is second to none. Their systems are constructed using 300 series stainless just like Borla. You will be hard pressed to find anything other than rave reviews. Feel free to shoot me a PM if you have questions or would like a price.

I can't wait for mine! Chase won't steer you wrong! And stainless works staff is top notch too. Had the opportunity to meet and talk with Anthony, super cool and very informative

Yep, I'll be buying this Chambered Exhaust from Chase as soon as I can sell off enough other stuff to be able to afford it. And then someday (after the warranty has expired), hopefully I can get some SW headers to go with it, maybe even the stepped headers if I have enough money to spare!!!

You ever held one of those stainless works bullets? Lmao.
I'd wager a bet that they're easily as heavy as my magnaflow cans. I used them on my old car (and loved them). Going to put some on this car with turn-downs at the axle, but they're certainly not light. It's a 3.5" stainless tube with another full-size 3" stainless tube inside it with stainless packing material. Heavy duty stuff
