I have completed what is the alternative to the $1400 Evolve downpipe for the 2G XC70. Made in-house at my facility with O2 extension it performs great and sounds wonderful. Turbo spool up is instant the way it should be. With the stock cat-back intact no addtional abnoxious exhaust noise is present. Sounds like stock just with amplified turbo spool-up sound. Once it's back on the hoist I'll snap a picture.

 

Yea a downpipe doesnt really change the sound unless you get rid of the hideus cat and get a high flow muffler.

 

Cat is gone.

 

High flow muffler?

My car has 3" dp and midpipe to 2 1/2 inch with 1 high flow muffler and its def. very throaty sounding.Lota ppl tell me it sounds like a turbo SUPRA.lol

 

Just downpipe. Stock resonator/cat-back.

 

Thats why.The stock muffler is such a horsepower killer.
