Im talking about gettin it installed and evertthing 98 1.8t A4

 

mine was 800

 

I got lucky and im getting mine for 350(used) and im going to put it on myself

 

the cheapest way to go would be to buy a magnaflow cannister and wave piping bent from cat-back....it should be around 150$ (+/-) and then bending and install should be around 200...all together you can have a pretty sweet system for about 300-350....gl!

I'd go 2.5" from cat to contanister....

 

If you already have a system that you bought like borla or milltek, it shouldnt cost more than $100 to install. All they do is remove your old exhaust by cutting and droping the hangers, then bolting up the new. Might be a little welding and supplies involved, but $100 would be fair for a typical install.

 

piping for me should be 100-150 and muffler, i got a cheap ebay muffler for time being and will move to a magnaflow soon, along with hfc and downpipe

 

My custom setup, including 2 new cat converters (+ install) was $700

 

500-800 for quality exhaust systems that sound good

 

I paid $915 /w installation for my Milltek Exhaust without Downpipe.

 

yea bro it depends on what you want, catback, full exhaust, or custom
i have a test pipe 3 inch and 2.5 inch downpipe and 2.5 inch pipe all the way to the magnaflow muffler the whole setup cost me around 670 dollars with installing the downpipe and testpipe my self.
