i didnt see any links on here for exhaust,? but any way, i bought this honda book on how to modify all honda acura motors, and i came acroos the exhaust section in there and was reading about how to gain the most power out of a header and exhaust system, they said to get the most power you would use a cat back system they have the lowest back pressure, but if you really want the most power you would want to do a custom straight pipe system, but they dont reccomend this because its loud and you have emmisions, well i live in alabama, where we dont have emmisions so i ordered me a header and im doing a straight pipe system, no cat, no muffler. so what im try'n to get at is, do any of you reading this own a 5th gen lude or have friends that do that have straight pipe? if so how dose it sound? im just try'n to get an idea before next week when i put it on, i will repost on here when its done just to let you guys and girls.... know what its like.
I wouldn't sacrifice so much comfort for such little performance

However if you just have bolt ons then I personally wouldnt do it becuase 1 its loud as hell, and 2 you wont be making a whole lot of power from just bolt ons and straight pipe.
Its up to you tho its loud as hell and ull smell your exhaust fumes haha
If you want to get an idea of how loud it will be - unbolt the axle-back portion of your stock exhaust. Then drive around with it like that (missing the rear muffler). Then imagine your exhaust being even MORE obnoxious than that because of no resonator . . . I guarantee you'll change you mind about running straight pipe.
Straight pipe is fine . . . as long as you never drive past a cop. or listen to music. or drive past houses. or ever want to talk to anyone in your car again.

yeah i seriously suggest u just get a catback, and mayB a str8 pipe for the cat if it really is important 4 u to have a totally free flowing exhaust....but yeah, i dont know y u would want to do that unless ur running some sort of forced induction. The power gains r pretty small. There was a post up like last year, about how unresponsive the h22 is to mods--as compared to Honda's more superior engine, the K series, which gets atleast twice the gains with a bolt on exhuast than a h22.
one thing u COULD do, if u so badly think this str8 pipe idea of urs would b a great idea, is strip ur interior, and line the entire interior with fat mat, and double layer the floor. This will keep the sound out of the cabin. But yeah, just as Daemione stated, lots of unnecessary attention.
You should really read osme good exhaust articles. You do to some extent need back pressure, why do you think race engines have headers or exhaust at all. Basically the backpressure done right creates a zipper effect to help exhaust gases become expelled more quicly than the piston and valve ports can do on their own.
I also say it is going to sound like bad. I have driven around with just the cat...and then with 3" from the cat dumped at the rear axle. Needless to say, I drove around like that for about 2 weeks...and then I ordered my Skunk2 catback. I don't have any dyno numbers, but the open felt like it pulled harder up top, but it was really sluggish on the low-mid end of the rpm's. The Skunk2 fixed the low-mid, and I do feel I lost a little on the top. Personally. Hondas' need a resonator and a good muffler to sound right on the street.

You don't need ANY backpressure in an exhaust. The effect you're talking about is scavenging, and it has nothing to do with backpressure. It's more of a vacuum than backpressure!

oh, whoops. Shows how much I know lol. I was just trying to say exhausts are a good thing.

I agree with everything you said escept the part about needing a resonator. Although I wouldn't recommend anyone else doing it, I just have a high flow cat to a magnaflow muffler with 2.25" piping and it sounds pretty awesome if you ask me.
'Is that a dump truck??...Oh wait its that Prelude'
Its going to be so loud. If you can bend it yourself Id say go ahead and do it all. Just something to do, but I wouldnt keep it on for more then like 2 days.

unrated 98 - i drove with an open header for about a weekend before i could get it welded together...loud as hell and i would not suggest it. low end power is shot...not there.
btw - where do you go to school? I went to Oak Mountain and now am at UA
You don't need to ditch a muffler for the thing to perform. Also keep in mind you're talking about only a few HP difference from sounding good to sounding like ass. No cat no resonator no muffler = deaf. You would probably get a ticket for excessive noise, even in Alabama.
I don't remember the guy's screen name but a local guy here put an S2k muffler on his Prelude and really likes it. It's only 2" in but performs decent and doesn't sound too bad or loud.

so i ordered me a header and im doing a straight pipe system, no cat, no muffler. so what im try'n to get at is, do any of you reading this own a 5th gen lude or have friends that do that have straight pipe? if so how dose it sound? im just try'n to get an idea before next week when i put it on, i will repost on here when its done just to let you guys and girls.... know what its like.
MOO!
