I want to do something with my exhaust. Maybe stick with the stock back pipe and get a high flow muffler, just not a loud one. I don't want to spend too much like in the $100-$200 range and I don't really care what brand it is as long as it does the job. Any sugestions? ------------------ 95 Civic Ex Coupe auto H-Stock

DynoMax, RaceMagnum. Best bang for the buck, Unmatched in flow, straight through design, and not to loud! Dave

Can exhuast mods change the class you are in?? I heard you just had to be under like 95 db or something. Cause I've got headers, no cats, a 3.5 inch catback, sprint car muffler.... ------------------ [b] Quik's Silver [/b] 1998 Camaro Z28 1LE A4 [url="http://http:www.geocities.com/crazyquik/LightningQuik.html"]I Lost 246 lbs On This Plan!!![/URL]

The only exhaust mod you are allowed to make is an cat back system. Meaning you can chage any part of the exhaust after the Catalytic Converter to the tip. Headers Move you to Street prepared class or street Touring ------------------ KillBugsFast GS - '00 Type R

As Stageone said, you can changea anything after the cat. From section 3.5 P57. Adequate mufflers are required. Now for the fun part. What's adequate? According to 3.5, any car that's deemed to loud, by the Event Chairman, has an inadequate muffler. We've had cars run with no mufflers and sound fine. We've also lost a site due to excessive noise. If your running in an industrial park or an airfield, wide open may not be a problem. Just be aware of the site location and how difficult it is to get sites if someone give you some grief for how loud you are.

Hmm, well if I get addicted to autocrossing (which everyone tells me I will) I might have to put the stock manifolds and Y pipe back on. Man, thats really gonna hurt my ETs too at the strip, and it wont be as fun on the street either Ah, the challanges of trying to have a car that will do everything.

Just put the cat back in when you solo and run in ST.

[QUOTE]Originally posted by Offside: [b] No need for that. Just put the cat back in when you solo and run in ST.[/b] I'll still have headers, and isn't there a 3.1 liter limit in ST? My 5.7 liters with headers would be in SP wouldn't it? That is a good idea though, just cut my off road Y pipe, and flange the ends where I did and put the cats back in, keep the sections I cut out and make them into test pipes with flanges to put back in when I'm drag racing, or daily driving or whatever. Also, on the topic about getting a muffler, you could make one. Just get some metal screen or mesh, maybe a 2 ft long strip at the most (a Civic with the cat on shouldn't be too loud) and roll the mesh, then insert it into the exhaust pipe. Some of the old SoCal hot rods had "straight pipes" under the doors with mesh in them to knock the edge off the sound. Or, you could get a cutout if you just want this for track use. Oh wait, I know people that use them on the street
