Muffler- I suggest only muffler/ axle back and not a full cat back system because Mugen (THE Honda perf authority) has found on several models that including a new B-pipe provides little or no improvements over the stock B pipe. Of course, this doesn’t stop just about every manufacturer of full exhaust systems from including the B pipe and passing on the accompanying expense.

After reading this I got a $150 Dynomax dual stainless tip axle back (quiet) and an $75 OEM replacement B-pipe (midpipe) for my '91 Si. It had NO exhaust when I got it, just a short section of rotted pipe bolted to the cat. The rest had evidently fallen off long ago. After I installed the above mentioned parts it seemed to me that low-end torque picked up with no loss of top end. You don't need a bigger B-pipe unless your engine is heavily modified (mine is stock) or you going forced induction. The stock muffler is the big power robber.

The thing that I don't understand is how those stupid fart cannons can be so loud. When my car had NO exhaust it still wasn't really that loud. How do you get away with calling something a "muffler" when it acutally AMPLIFYS noise. :wtf:
