I am going with a 3 in turbo back no cats. I want to get a cobb stage two. Do i have to wait on the exhaust. I guess what i am saying, is it ok to put on the tbe with out the reflash. any adverse effects. I think it will be a month or two before i can get the reflash. any info would help! thanks

 

You can put on the exhaust before the reflash, no problem. You won't be running optimum, but it runs ok.



:banana:

 

If you put the exhaust on before the reflash, you'll notice a nice improvement. Then when you get the reflash, you will be in heaven.
