Hey guys! Been reading all ya useful info on the site and have become hooked on getting the most out of my 2003 Astra 2.2 SRI. Have done the old air box mod, ordered a Piper Downpipe Cat Assembly and the Ebay bargain powerflow cat back system is polished up and ready to fit. Have also ordered a chris tullett exhaust manifold, unfortunatly this may include a 5 week wait for arrival 🙁 Has anyone had experiences of these manifolds good or bad? Tried regal but no joy and piper have discontinued there manifold due the the problems experienced by customers including some guys on here. Any guidance on getting the most out of my Z22SE short of getting rid of the balance shafts (am to lazy to pull the engine out of the car! :oops: ) will be greatly appreciated!
I Know there are loads of topics on here about tuning (have been taking great interest in reading them!) but just wanted to tell you about my obsession (car) and say HELLO!
