I‘m looking for an exhaust system for my 2005 Audi a4 b7 2.0 non-turbo. there are so many different systems to fit all the type of engines, but just not for the non turbo. Is this because the other systems still fit or because its a rarer model than others. maybe there just isnt a exhaust out there for it? Just a little confused. any help is greatly appreciated. thanks in advance
Usually Audi performance parts manufacturers do not produce exhaust products for non-turbo models because of a few reasons. One, most Audi non-turbo engines are not very tunable, meaning they do not upgrade easily. Secondly, the performance gains on non-turbo vs turbo models (as far as exhaust goes) is alot different. HP/torque gains in non-turbo models tend to be alot less significant than turbo models, pretty much making any products that the manufacturers would sell for non-turbos a waste of costs to produce. That is not to say that there are no companies that make an exhaust system for your model, but alot of the times they release these systems after a couple of years (at least that is what I have noticed) So to sum your question up.it is hard to find non-turbo performance parts (mainly exhaust) because there is a smaller demand for these parts, the performance gains are minimal next to turbo models, and they are a little harder to tune
