You can - not to say you can't. But I've never used this brand before so I don't know how it affects performance. It looks like a Jasma brand extractor.
Compare that Jasma with this :

This is the Powerzone one. The way the collectors merge is different. Powerzone is a more reputable brand but if you got budget have a look at Supercircuit exhausts as well. They can do the whole exhaust. There's a few brands out there - you need to get opinions from people who have used them.
My old car had the whole exhaust done by Everco way before they were expensive. I had the front to back done for 1300 back then (close to 20 years ago).
