hey all just bought an wrx sti uk wanting all your expert opinions on the best exhaust upgrade also what engine oil you all use many thanks matt

 

On the Engine Oil question - please use the search facility .... it will be wise to use what the Handbook says.

 

If you read your handbook it gives you the range of oil you can use. I have 2.5 WRX STi and use Shell Helix 10W40 fully synthetic in mine for top up as this is what my dealer provided for top up with my car and also corresponds with the handbook

Exhausts are down to personal preference and to how much noise you want. The Afterburner is very popular if a bit loud.

 

Re: exhaust, all depends what you want out of it my friend. Do you want subtle noise or abrasively loud?

 

afterburner vortex is the way forward my friend

id recommend.... getting yourself to a meet and blagging rides in other peoples cars. Some sound quiet when your next to them but are loud when on full chat or burbbling at part throttle. Others can be heard miles away but arent loud, some are seriously loud but dont travel very far. Best of luck.
