just having a nose at some sierra rs cosworth exhausts but why are some of them different when coming up to the downpipe?? have a look at these 2 pictures to see, sorry me and my friend are new to the sierra scene! bottom exhaust is our original system
Standard is a 2 pipe system that joins back into one at the downpipe. Some aftermarket ones replicate this idea. others use a 3 inch single pipe system
