just was wondering for the new future there is only one muffler shop in town(minute muffler and brake) They carry all of the 2005 ractive muffler lineup and dynomax series mufflers. So a few questions

1.)how restrective is the stock muffler on the turbo's???
2.)Which muffler out of the 2005 ractive lineup would be the best?? does it have to be a 3 inch muffler??? does ractive even have a 3inch muffler???
3.) I may later be upgrading to a full 3 inch system so i would like to transfer this muffler to it, so what are my best choices???
4.)Would changing the muffler casuses and hp gains, extra boost, gas mileage etc.(basiclly the advantages of a changing the mufffler)

1. pretty restrictive
2. dont know. never heard of this company but as long as its 3' in 3' out and is straight through i dont see an issue minus noise
3. cooleeze makes a DIY exhaust 3' pipes iirc that you can do and transfer your 3' muffler over
4. yes to all. ease of flow out will help things alot. quicker spool and less work for the motor helps also. my bro gets only like 22 mpg on the highway with his stock exhaust and i can get 26ish with my full 3in.

That's not all that conclusive, I get better than 26mpg with my Supra and I still have the stock catback. (HKS downpipe and no cat, but still stock catback).

I do agree with you though. :)
