exaust

[tomnlindsay]

would putting headers on with high flow cat and bigger pipes with a stock muffler do anything for your cars performance? please bear with me i am very new to the mod world. also trying to DIY.

No, it wouldn't really help. Read this, it will help you understand some things since you are new to modding.

I am not trying to be a dick so don't get me wrong. It's just easier to read it as it will give you a better idea than I could explain.

wow thanks for that info. i was hoping to stay away from the muffler though cause i bought a 94 accord ex with a full exaust and the cops were on me like no other. i just got my lis. back.cause of the exaust was so loud. i miss that car so much!!!! just wish i could duplicate that power minus the exaust being so loud. anyways thanks for the help.

buy an s2k muffler and a resonator. its really quiet and you get your performance gain

[tomnlindsay]

how much would the s2k muffler and res cost and would you clamp them on or weld them? i live in wisconsin (milwaukee) if that matters on price.

[Law Grandeur]

i payed 50 for my s2k muffler. have it welded. that price would depend on the shops in your area.

cool thanks for the info. this site rocks with response time. i tried the honda forum and they sucked compared to this and it is greatly appreciated

there is a certain rsx-type s muffler you can use too. use the search on the site cuz i cant think of which year rsx it was from. i'd show you my in cabin video but all you really hear is the h22 not the exhaust lol. idle was really quiet. the car was quiet enough to not get harrassed by cops all the time. i was followed a few time but they couldnt pull me over. it says honda on it so if they say its aftermarket show them the honda logo on it. if they complain about your pipes say you got them replaced cuz it had a hole in it. it was only loud when i floored it

[tomnlindsay]

would you say it to be about the same price range?

[Law Grandeur]

that i dont know. just look for local peeps who modded their rsx or s2k and have no need for the muffler. i posted a wanted ad up on a local florida car forum and bought one 2 or so days later. actually ended up being a member on here lol

Opening the exhaust up will give a gain in power, but not a huge one. To really make a significant difference with the F22A, you really need to work on the head and replace the cam. The F22A has a LOT of potential (take a look at Bisi Ezerioha's drag Insight making 400hp with a naturally aspirated F22... heavily modified, of course!)

If police attention is an issue, you'll want to stay stock, use a stock higher performance muffler like the S2000 or RSX-S (both have been used with nice results), or get a system like the Apexi World Sport 2, which is very quiet.

A header (you only have one) does very little unless you get a GOOD one. The only really good one for the F22A is from Bisimoto (same guy with the Insight), and costs a pretty penny. WELL worth it if you're truly serious about performance, and cheaper than comparable headers for other motors (Bisi is cool about keeping the scene alive, not milking tuners for every dime they have). Still, it's possible to buy a CB7 for less than the cost of that header! I WILL have one someday...

A "high flow cat" isn't really necessary. Honda cats flow well enough as it is, so there's no real need to go "high flow", or get a hollow test pipe. DO NOT ever hollow out your cat, as it will increase noise and actually reduce performance.
If you want to shell out cash for a high flow cat, get one that actually does something. Go to www.sms-products.com and get one of theirs. They are the makers of the famous SMSP header for the H22, so they know what they're doing. They aren't extremely expensive (prices range from $100 to $300), and you'll get something that actually works.

The stock F22 iron manifold looks like a pretty sorry piece to me. No cross over for cyls 1 & 4. It's a simple 4-1 setup. A header would be 4-2-1.

A hi-flow catalytic converter is simply a regular cat with larger inlet/outlet pipes to match the rest of the modified exhaust system's pipes.

If I were tuning an F22, the exhaust system is where I would start.

thanks for the info guys this site is wonderful. i plan on coming back to this site often. hopefully i can get pics up later (when i get a camera)ps it sucks without one!!!!

The manifolds are different on the various F22A motors. The one you are describing is the F22A1.

4-2-1 is best for low to midrange. Full race headers are actually 4-1 in most cases.
