Assuming a car with intake and headers, is there a significant power difference between only replacing the b-pipe and getting a catback system? Sound concerns are secondary to me, and if the catback doesn't at more than a couple of hp over just the b-pipe it would influence my decision. Thoughts?

 

a catback gets its hp from the bpipe- theres no hp in a muffler

 

Or at least nothing significant in the muffler. Our stock one does a good job. Just get the b-pipe

 

I thought about just getting the B-pipe too. Any of you noticed the crunch before the first bend on the stock b-pipe? My friend pointed that out to me while we were installing the rSb. If it's like that on all 5th gens, then we're being robbed of HP. I'll be really ticked if it's only me.

 

ya there's a crunch there, I saw it when i was putting on my Straight Pipe.

 

Excellent. Save some money that way. If the headers turn out well sounds like headers+b-pipe is the optimal exhaust system for performance at least.
