787B

i am still trying to decide....single or dual.

well those of you with duals show me pics and try and convince me to get duals.

It's simple really. You just have to decide what you want more.

Single
-Can deliver slightly more power
-Looks like your exhaust is broken because the other side of the bumper still has the cutout

Dual.
-Quiter
-Looks complete and keeps the "symetry"....I probably spelled that wrong.

That's easy. TRUE Dual output dual exhaust (STEREO). It flows better than the single exhaust.

I think some of the SCCA outlets sell the dual output exhaust manifold.

you might need dual for your 787B

You can hardly see, but here is the HKS on my TII.

You sound like you don't really want a dual setup, but are trying to talk yourself into it. I personally like the single sided exhaust. It is much easier to take on and off by yourself. I like the idea of not having a split in the piping, just a straight through shot. If a single sided exhaust such as an N1, which I have, looks funny with the little notch on the other side of the rear bumper with nothing to fill it in, just take it to a body shop and get them to fill it in or something. I will never go back to a dual setup, I have previously had the HKS dual exhaust. It was a nice exhaust, but I like the N1 so much more.

unless you have separate dual pipes all the way from headers, dual exhaust won't give you anything that single cant...

and single is...
cheaper
lighter
BETTER!

go single!

Single is also loud as ****. I hate that. Even my FB runs duals back to the rear axle.

Preach on Brother man, preach on.

I am still debating between the two myself...

I'd do with the duals, they look better and work better. Here's what I posted when Rico05 asked the same question:

"If the pipes are the right size, a dual will always outflow a single. I don't know what size those off the shelf systems are, but if you split the 3" into dual 2.5" pipes (with 2.5" mufflers) this will outflow a single 3". Yes, the Y creates some loss, but the dual 2.5" pipes have a total of 40% more cross-sectional area than a 3". Put another way each pipe and muffler only has to pass half the exhaust through a pipe only 30% smaller. The net result is more flow. This is simple engineering, not rocket science. A dual may also weigh (say) 20lb more, but since this is less than 1% of the cars weight, I don't think you're gonna notice. Looks and cost are a strictly personal thing, buy what you think looks best and you can afford. It's your car."

in all seriousness, if you are into looks get a dual catback, if you are in a budget and don't mind the louder sound go single

AcmeSkater

If you don't want that hole on one side w/ a single then take a rotozip and chalk a line on the bumper from the top on one hole to the top of the other and cut a strait line and you have 1 bid hole w/ a 4.5" exhaust tip plus it will lessen drag a little bit(tiny tiny tiny bit). Jut what im going to do, I want the sound (ive heard that a single is deeper than a dual) I want people to know i mean business. But its your car so you decide, just throwing ideas out there.

Racing Beat is great. Here are some before and after pictures when I installed them on my FC.

yo gingenhagen i love the ramps.

I made some ramps that I use for only the front tires but i never thought of making some to drive right up on

I switched from a custom 3'' single setup to the full racingbeat turboback.

It cut the sound down almost to stock(which is one of the primary reasons I got it), and I definatly felt a noticeable power increase. I like the look much better than my old coffee can muffler; but I still miss the throaty growl of the single a little bit. I have people ask me frequently if its the stock exhaust- good if you're building a 'sleeper.'

I recommend dual.

i have dual and i love the way it looks and sounds (unlike civics mine has bass to it) ill try to get a pic of it up i just first have to take one

Kenteth

LOL, you'll have to drop a v8 in it, period. If you don't like the sound, don't drive a rotary.
