whats the best test pipe for the buck? whhich is the best website?

 

i like eurocode http://www.ecodetuning.com/shop/cart...tail&p=671

 

yea i looked at that and it was only like 145...but next question is what size pipe..am runnning a stock turbo but in three months i get the k-04 upgrade from Awe-tuning so i was thinking 3" but is that a bit to big?

 

it will be fine IMO i ran one with a k03 and I had a 2.5' exhaust

 

so 3" to big

 

thanks

 

2.5' or 3' will probably be just right, if your going with the agressive k04 files 3' might be nessicary but 2.5 would be just fine either way

 

thanks...and do you know if it is smog legal to have the cat relocated under the car because i want to make it so i can unbolt it so i can replace that section with stirght pipe?

 

ahh nice new sig badluck... so are you gonna get an old a4 and make it a project or what?

 

As long as your 02 readings are normal and there is no CEL you should be fine. Shouldnt be TOO hard to relocate with a couple flanges welded into the exhaust after the downpipe and some wire splicing.. Might be time consuming but probably not hard. I dont see why it would be illegal to relocate as long as its doing its job.
