Just finished fitting my cat back exhaust to my sti blob and am delighted with the results. Was a bit weary at first as hadn't heard of the make b4 (Cobb) but it is stunning. A fantastic fit and sounds perfect. Would recommend to anyone

 

Nice one, whats the tailpipe like? sound nice?

 

2 and half inch tail pipe mate so not massive like some and sounds just right. Lovely burble but not screaming like some saxo vtr lol.
