My little 06' xA is getting old and showing some signs of corrosion and rust on various parts. Would replacing the stock exhaust with a new stock exhaust add back some power?

I am the original owner and have always maintained and treated the car well. Also have added kn intake, 421 Weapon R Header, lighter pulley, and some more things here and there.

I feel like the car doesn't have to go it used to have.

 

i replaced the whole system from the down pipe and back spent a total of $2K for all that and they installed it...

 

2k???? It's like 10-16 bolts and 400$ in parts. Ouch

 

not for OEM parts it was 1500 for the mid pipe with the cat, i supplied my own O2 sensors, and around 300 for the OEM muffler

 

still seems way overpriced.

as for adding power that seems to have diminished...i would just start with the basic "tune up" options...clean your maf sensor and replace/clean air filter, new spark plugs and maybe some fuel system cleaner...and motor oil/filter and transmission/filter. i kinda slacked on the maintenance on my car for a bit and did all those. it wasnt really faster, but definitely had a smoother feel to it after.
