How much would a gmmg cat-back and slp cai lower mt e.t.

 

I don't know about the gmmg and the slp, but my single outlet Flowmaster and Moroso CAI gave me an average of 0.2 in the 1/4 with no other mods. A good CAI is one of the best 'bang-for-the-buck' mods you can do!

 

CAI and headers provided a 1/2 second improvement in ET and 2 mph, plus better gas mileage by 1 mpg. When I added the cat back the following week there was no gain.

The other key is to have some drag radials so you can actually hook up and not spin the tires.

 

i ran a 14.4 with just a flowmaster, then when I got my CAI i ran a 14.0... And I just ordered my MAC headers today.... 13s here i come hehe

 

I went from running 14.3 @ 99 to running 13.9 @ 102 with a CAI and Borla.

 

I saw a 0.09 second improvement in my times with all the mods in sig. you can see before and after. although track conditions weather, and my slipping clutch played a role in totally messing up my times. I just wanted to after that run.

 

i strongly suggest getting a cut-out, i went from a 14.1 to 13.8 at the track recently.

I will get a cut out as well as a catback the cat back is mainly for sound.

 

With Lingenfelter cai and a cut out i ran 13.3 @ 103mph.

 

those are your only 2 mods??? and ran a 13.3????

 

Yup, believe it or not, those are my mods and my time.

 

That seems almost impossible, what did your car run bone stock?

What gears?

Were you on et streets or what?

I want to run a 13.3! What are your secrets????

 

My car ran 14.09@98.5 stock. So far I've ran a crappy 13.80@102.76. My best trap is 103.7. Thats with only an SLP CAI and Borla along with a 2.16 60'.

 

Generally id say 2-3 tenths...

 

sure you didnt have nitrous on that run.......friend ran a 13.6 with headers, exhaust, cai, and 75 or 100 shot of nitrous.
