Hi I know there is a 100 threads about downpipe size but just want to get some personal advice.
The engine is standard apart from veccy C pipe with K&N, egr blocked and a Chris Tullett manifold.
I haven't drilled out the pre cat and want to get a sports cat so thought it would be easier to buy a new downpipe done already.
I have seen this dbilas downipe http://www.dbilas-shop.com/Products...lytic-converter-Opel-Astra-G-Z22SE::7319.html
The downpipe is 2.5" do you think it will be to big for a standard car even with 2" cat back? and what is the quality of dbilas like.
Any advice would be appreciated cheers
