im planning on purchasing a 70mm invidia exhaust with dual tips and a 70 mm test pipe. how much does the dual exhaust weigh? what are the power gains? If anyone could give there 2 cents on this combo please help! thanks

 

search invidia

 

Oh man, get ready to hear all about the search button and how it is your friend and then multiple links to treads :S

best of luck,

oh yeah, its loud as shit fyi!

 

it's HEAVY! well compared to a single. I'm making a 70mm headerback after Christmas when I get a chance. no resonator. I have a 63mm headerback w/ no resonator and I don't think it's that loud. Then again "loud" is subjective

 

the dual weighs like 25 lbs, which is less than half the weight of stock.

 

Hey Bro.!
Check in the "Engine and Drivetrain" Section and look for Steve@Evolution. He has cheap prices and he also has dyno plots for the Exhaust and Test Pipe so you can see what they individually gain.
