My Dad has A TS50 and I was wondering what free modifacations are available I guess we can cut out the cats first,is there anything else?And what else can be done thats not free?Perhaps some kind of computer flash tuner,air filter any ideas welcome.
There's little if any point in removing cats. It's also illegal. Just get the exhaust done if you want less restriction...and much better noise. Extractors too. These two things are usually the 1st mods done and are well worth it in my opinion.
