Good to know. I'm not necessarily looking for power yet, that will come a year or two into my warranty.

CEL is a deal breaker for me. If I can clear it without a tune, that would be nice.

You can get a scan tool to clear the CEL when they reappear if you like.

Is it just one time, or will the CEL appear every day?

you will be amazed when you decide to modify the car what a difference it will make in the fun factor. I lived with my car for 2 years w/o moding and regularly went to our local road course but ive been racing with 850 hp and man its a blast. you wont regret it. good luck

Thanks. I wouldn't mind hitting 600 to the wheels, but thats all the power I'm interested in. My Shelby made 600rwhp and I was happy, but it was 200lbs lighter too. I want to try and shoot for dropping 200lbs. Less weight means more fun at the track for me

I run with a CEL on all the time...... No big deal..... but I do get a CEL check every month by a Auto Parts Store that run free diagnostic CEL check to make sure that my O2 sensors are the only things that show a malfunction....... When I get closer to my warranty to run out then I'll get a tune....

You will lose 40 pounds with a stainless works retro catback and another 30 with stainless works headers and another 10 no cats over factory hope this helps you good luck

80lbs, that sounds like more than I hoped. You're sure about these numbers?

[Mike-ZL1]

Yes I am sure giver take a couple of pounds I weighed parts manifolds factory cats and had to weighted factory exhaust cat back to ship after I sold which is 100 pounds and all the new parts come in boxes that have the weight on them to ship headers were easy to weigh high flow cats also hope this helps good luck

Oh I see, the weight of all the parts is about 80lbs. But when I replace them with lighter aftermarket parts, I will be putting like 50 or 60lbs back on the car. So savings is probably like 20lbs-ish.

Not enough weight savings to be noticed over the HP increases...

[Mike-ZL1]

No the weight savings is what I said around 40 pounds for stainless works cat back and long tubes save around 30 pounds high flow cats around 8 pounds less than factory parts so yes it is worth to money for performance and lighten the car and the 4 inch tips look better out back compared to factory 3 inch so total weight savings is around 80 pounds with full stainless works exhaust got it now good luck

Holy crap. In that case, this is definitely my first mod.

Mind sharing what it cost, parts + install?

Thanks for your help!

You are going to have to get pretty extreme to cut 200 pounds from this car. I have weighed my car probably 6 times as I've gone through different stages of the build. I have a 3" magnaflow cat back exhaust system now and that mod alone saved about 40 pounds over the stock exhaust.

The biggest potential weight savings possible on the car is the front seats. These power heated front seats are around 70 pounds each. You can easily get seats in the 20 pound range if you are looking for big weight savings. The front and rear crash bars can shed a lot of weight but then you mess with survivability. You can lose a lot of weight with rims and tires, brake components....
