no, that y pipe bottlenecks down to almost an inch. the only thing any piece of your stock exhaust system is good for is restricting horsepower like the plague.
it's gonna cost ya, but save up for a set of 2055's, and a 3" catback of your choice. you'll add at least 40HP and be set for more modifications down the road. I skimped out on exhaust, and i had to go back and change everything. its not worth it. flowtech hedders should be banned from the us.
I understand if you're on a budget, I am too. but wait a month or two and get the 2055s. trust me.

I agree with all that is posted above. You do not want Blowtech headers. Everything about them screams frustration. They leak, they have a horrible y-pipe design, and they perform like poo. You will be much happier with SLP's, Mac's or Hooker 2055's. You get what you pay for with headers. IMHO, if you want to buy new headers and have less than $400 it is better to stick with the stock manifolds.

The stock Y pipe is a big horsepower robber. Need to get a good aftermarket one.
