i have the Fabspeed bypass pipes & they sound good but get on my nerves on long drives, i seen these gundo exhaust hack & i think thats what im looking for my only concern is what will be the diffrence between the 1" & 2" cross over pipe? please help Thanks.

 

I see you have seen this thread too:

Anyone else out there know if 1" or 2" has any much of a difference with sound quality?

Will this mod also cause a possible decrease in horsepower since it appears that it can cause turbulence in exhaust flow?

Thanks for all the experts out there...or those that claim to be experts

 

Funny thing though is that Gundo is now running with an OEM PSE. So I guess it's not THAT much of a waste of money.

 

anyone? PSE is the sport exhaust for the 997 right? whats the story with that hows it work? what size is the crossover pipe on the pse?

 

OEM PSE and the hack are nearly identical in sound. 2" is the right size

I went with PSE as I was looking to go as stock as possible and found a huge bargain. That was prior to my AWE Cats and X51 headers :-)

 

Thanks for the input Gundo. Which had a better sound in your opinion, and was there any drone in the "hacked" exhaust?
