It depends, what are you changing? What year is your car?
This is a discussion on Exhaust FAQ within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; I'd be more worried about the health of the motor. It depends, what are you changing? What year is your ...
I'm changing the stock exhaust to the SRS Type-RE. It's a 2003.
Yes it's just the catback exhaust system
You don't have to do anything for just a catback. Potential power gains are negligible, no change in mpg, nothing.
Install and enjoy the sound.
I have a stock 2011 STI sedan and am looking at the invidia q300 catback. Can I safely run the exhaust without reprogramming (w/ an accessport) the car as long as it's the only mod? I plan on doing more and know that I will need to get a V3 in the future; I was just wondering for the time being if it was fine.

Whats the opinions on full custom turbo back compared to a kit from say Cobb or Tanabe?
Interesting observation on my car. Put a nameless catback on and ever since then the 2015's fuel economy calculator has shown lower fuel economy. Not by a ton, but has made it more accurate in a sense. (as in, before if I averaged a true 26mpg, the computer would say 29. Now if I average 25mpg, the computer may say 26).
Anyone else noticed this?
I am completely new to owning a Subaru; I ordered my 2015 WRX in September and should be taking delivery in mid-December. These are my questions:
1. Is a catback exhaust much more of a power improvement/sound difference than an axleback?
2. If so, then is the catback really worth the extra money over a catback?
3. Which catbacks, and which axlebacks would you guys reccomend?
I've listened to countless stuff on YouTube, but hearing it in person seems to be different. I'm looking for mid loudness, with a nice low, powerful rumble.
Thanks for reading, and any input!
