My confusing decision on cat-back exhausts

Alright there's just only one question I need somebody to answer before I go comparing and picking out my Catback Exhaust. Generally theres always the arguement about which ones sounds better and which ones look better. But, what I wanna know is that which exhausts are the ones that perform the best. Lets not think about sounds or prices. lie for example many people say the N1's are the ones that has the maximum flow for a pretty much stock lude. Brands like indivia, apexi, skunk 2, obx, and megan racing all currently have their line of N1 style exhaust. Then theres the quite ones like the greddy sp2, apexi ws2, tanabe ultra medallion. Is one or the other going to feel different in terms of power? Alright lets just leave it plain and simple, I'm looking for an exhaust that has maximum gains(no restrictiveness) for my stock lude. Any I should stay away from? I'm not really that type of person who would spend 500+ for an exhaust just for the sound, I want to see gains also. Hope you guys know what I mean.

Re: My confusing decision on cat-back exhausts

to be honest if you go with a high quality name apexi, greddy, skunk2, tanabe etc than an exhaust is an exhaust. you just need to find what fits your liking. ie: sound, size of can comin out the rear. i def would say no matter what you go with you should stay 2.5"+ throughout.

do you plan on header, collector mod, hi flow cat? do you already have an intake?

stay away from ebay brands and obx. not sure who else.

good luck and keep us posted.

Re: My confusing decision on cat-back exhausts

You sure you want a cat-back when a custom setup can be had significantly cheaper with the same benefits??? (I got a ceramic header... not ebay... and high flow cat with my setup and still spent less than a catless aftermarket setup). I can't really help if you are set on a cat-back setup, but if you consider custom I have some experience.

Re: My confusing decision on cat-back exhausts

The best exhaust setup for any H22 is a full 3" header back exhaust. There are numerous posts with dyno sheets proving that even a 3" crush bent exhaust will outperform just about anything else out there for the H22.

Personally I'm going with a 2 1/2" custom setup with a Ecut and just use that, however I'd like to do a full 3" setup with a few vibrant resonators and a vibrant muffler.

Nah definitely not OBX, but my ongoing debate has been going between one of my favorites Greddy Evo2 and also the super lightweight Buddy Club Pro-Spec. This video is what made me decide on the Buddy Club pro spec. (this one is stock with just an intake)



I have an AEM v2 already, and yes I had been planning on doing a 2.5 inch collector mod on a mega racing header, and getting my 2.5 inch high flow cat (I believe its magnaflow) from my local muffler shop that will help me install these parts.

yeah I understand, and its addicting to hear catbacks on youtube and wanting to have your car sound that way lol. But really its just that like I stated before in your other post that I don't have any local tuners like blueridge, and that does mandrel bent 2.5'' piping. I talked to my local muffler shop today, and they told me they can't get me the header, but they can get me a high flow cat and full piping with a muffler. He doesn't do mandrel bent, and says that that only comes from factory brands (greddy, apexi). Oh and also It won't help if I wouldnt know how it sounds until I install it, and how do I know I'll make gains? As you see I'm really unexperienced with this stuff so thats why I just went with a branded catback.

Re: My confusing decision on cat-back exhausts

The Greddy Evo2 is an amazing exhaust - I like it and it's deep toned as well

Re: My confusing decision on cat-back exhausts

Theoretically, the straight through design of N1, Evo2, etc. is the least restrictive. In the end though, the gains seen by one of those over a twin loop like WS2 or Ex*Mag are minimal, and you're better off getting the sound you want for the money you're spending if noise is a factor to you.

Re: My confusing decision on cat-back exhausts

Damn, you are taking this seriously.. Buddyclub (that would seem unique)... best of luck with the decision. How's the price compare to the Evo? I would go with the cheaper, haha, but I'm cheap, built my entire 2.5" exhaust, including hp racing ceramic header (Magnaflow Cat/Res, Nopi N1 style muffler) for under $500 (good websites and the hookup at my shop)...

... but custom is always going to be cheaper, that's why I have it, haha.

I like the buddyclub for the "super light weight" thing... how much lighter than the Evo?

Re: My confusing decision on cat-back exhausts

^LOL yeah I know I will take this seriously. Well see how you like spendin 500+ working minimum wage then youll see what I mean lol. Anyways, I have been looking for that answer all night yesterday, and seeing if it really is that lighter and is it really worth it. Personally I like it because of the sound but I just don't like the canister because its not polished. ( I know it sound stupid, but that'll make a difference on how my ass will look like forever)

So that makes evo2 some points further. But then again, everyone and their mom has the evo 2, its so damn common, but I guess its for a reason.

Re: My confusing decision on cat-back exhausts

Yeah, my nopi n1 style looks a little like that with a blue tip. It makes a nice deep sound for a 4 banger... not as different from the old h23 flowmaster 40 setup as I thought it would be.




sorry to anyone with a ****ty connection.

Re: My confusing decision on cat-back exhausts

hold on...... you can see a couple other charts on my members ride page... the torque through the powerband is the biggest advantage for daily driving, but the HP gain was nice too. Keep in mind, the exhaust was already on the car when they ran the p13 on the dyno....

Re: My confusing decision on cat-back exhausts

yeah alright I've seen those graphs already lol. How much gain do you think I'll have from my stock exhaust to a complete exhaust setup & tuned? Will I be around the 180's with a p28 or does it depend on my motor? I need to know how much I'll be looking at when I get this full header back exhaust done, so ZI know there wasn't any mistakes. Sorry bout all the questions.

Re: My confusing decision on cat-back exhausts

sorry,
I think it would be well into the 180s. Would you have a lightweight flywheel? that can add a little up top (I don't have one, might be the reason I made great torque, but was a little subdued up top). Every tuned h22a I have seen on the dyno (in person or from a reputable video) has made at least as much as mine. A h22a del sol put down almost 192, and a h22 civic put down a little over 185, but I made more torque than it. Point being, you can gain significant power (close or more than 10 peak hp, and 10lb-ft torque through the powerband depending on the setup... I think the open exhaust is crucial to get these gains...). The thing I noticed right away was the smoothness of the power. The p13 just felt rough comparatively... it was too lean on the low end, and too rich up top... It almost felt as if it wanted to hesitate in the 3k range from time to time, but the engine is in great shape, now it pulls from 1500 rpms and though I can't say it is fast in that range, the power is super smooth all the way to the top, which is higher and hits harder for longer...

I have seen stock h22s making way worse power than my p13... 140 was about the worst, but he had problems.. 160s are not uncommon I don't think... but with a proper tune and a few parts 180s should still be attainable... the h22a civic driven by my mechanic went from about 150 on some fake chip to the above stated 185ish, and recently for some reason his car dynoed a touch over 200... maybe he forgot to mention some upgrade...

Re: My confusing decision on cat-back exhausts

Yeah man as of right now I've ordered an Exedy Stage 1 with a fidanza 8lb flywheel. But that'll come later, since I'll have to save up for the more or less$500 job it'll be. But for now I'll try to order a p28 ecu on top of my evo2 and megan header w/2.5 inch collector. Which brings me to this question. Did you do a 2.5 inch collector on your header? Many say that headers that have those 2 inch collectors are basically stock replacement and VERY minimal gains. Anyway, I'll hope to be in the 180's or more. Have you ran your car in the track after the tune?

Re: My confusing decision on cat-back exhausts

I have not been to the track. My header is indeed basically a stock replacement but is ceramic... I think the collector mod is a great idea, and it would help gain some power, esp up top I would like to do it at some point. I wish I could have just gotten a Jasma header...
