Hey guys, few questions came to my mind this morning. First I read a lot of good thread about how e-manage is the way to go for boosted car, my car is not boosted yet, but I have all the regular bolt-on, Y-Pipe, intake and cat-back. I will soon switch from the Y-Pipe to Cattman headers, and hopefully get boost whenever I'll have the cash,( S/C or Turbo ) but meanwhile would I get any benefit in getting the e-manage now with the headers, I know I will need it when come the time to boost but what about slapping in without boost. I was wondering if the difference between the Y-Pipe and Headers make a huge difference.

Thanks for any usefull infos.

Cheers

AA
