Fit: 5/5
Power: 4/5 (noticeable power increase from stock)

Spec-D N1 Catback (Ebay 2.5" exhaust)

Fit: 4/5 Great, needs slight adjustments, some questionable bends.
Power: 3/5 Blame the D17, not the pipes...
Loudness: 4/5 Very loud until I installed an SRI

Very good system for the price.
Pros:
-Nice fit, tip diameter compliments the 04-05 exhaust bumper cutout.
-Polished Stainless is shiny!
-Deep, grumbly, throaty sound! Not ricey!
-Lightweight.
Cons:
-Droning sound going uphill. But disappeared with an intake upgrade!
-Low grade steel, will rust faster.
-Low hanging mid-pipe section, bad news for suspension drops.

Overall, I'm pleased, and at $115, not a deal-breaker at all! Budget exhaust with a bang! Just keep it well oiled up if you encounter road salts in the winter season.

Previous exhaust was a 2.5" custome exhaust from catback with a 1 chamber flo-pro v-force muffler with a 4" stainless double wall tip, it was too loud and after 4000 rpms and sounded wayyy ricey
New exhaust.........
didnt want to spend over 100 at my exhaust shop to put a flowmaster 40 on the car... so i got on EBAY lol
i ordered a 3" catback of all things.... needless to say bolted up perfect, sounds amazing, and quite deep, btw if you are wondering, No loss of power and for only $99.95 with free shipping, seems like a good deal to me, whether the stainless sucks or not
4.5/5 on sound, (would be 5 but its a 4 banger) love it though

noob style question. does anyone know what size of exhaust flange a guy should buy for a megan race header, currently bolts on to my stock exhaust. but i'm building a custom-ish exhaust and need to peice together the right parts, maybe i'll look at the megan site and see what it tells me. b-b-b-bbeats.

lucky for you mine is sitting in my room. 2" collector on the header. mine is for a d16/15

pwnsauce

just got mine on. agree with all ratings^ and second the 8th gen si statement. sounds nearly identical to my buddys 2010 si stock exhaust. might be a bit louder cuz i have headers too but heres a sound clip. not as loud as it seems in the video, and doesnt make the raspy noise while driving. also running no cat for now.

UPDATE!!!
So this might take a bit to explain... but now I have a FULL ebay stainless exhaust lol, sad part is CEL due to o2 sensor but oh well...
stainless 4-1 header, stainless catless downpipe (small resonator where cat would be) and a 3" catback with resonator and canister muffler/tip. Honestly...... it sounds amazing car is magnificently loud, and with the 3" pipe its growly, not raspy and farty.
Now on to the hard to exlain part... My bud owns a welding shop where which is a plasma cutter, so I had him make me 4 of the exact same 2 bolt 3" flanges. I had my Canister muffler cut off and had a flange welded to the original axleback piping and another welding to the canister, then I had another flange welding to a 80 degree angled 3" pipe with a stainless double wall 4" tip which pretty much makes my car fully straight piped aside from the small resonator in the downpipe and the resonator in the catback (compared to a gsxr1000 without a muffler) that one is for MESSING WITH PEOPLE/MAKING THEM MAD ONLY.. sounds horrible lol. And the 4th flange was welded to a bullet muffler and I had a 3.5" stainless tip put on it. Here are some pics of the car with each 3 diff pieces on it. SORRY I have no videos :'(

That is clearly the canister muffler that came with the catback

That is a view of the 3" catback pipe.

That is the bullet muffler with the 3.5" tip ( all it is is an oval muffler with a diamond shaped piece of metal on the inside that the exhaust goes around)

And thats the "loud-pipe" as its called where im from, I live in hicktown lol, so atleast 85% of the vehicles around here have an exhaust system on it, I just like being different and stupid, but the bullet and the canister sound amazing to me.

HKS Hi-Power Exhaust Axel Back

Fit: 5
Power: 2
Loudness: 3

I think it sounds great and has a cool sideways lean. Clears rear Progress with plenty of room to spare. No highway drone!

SixtyAte

I jut saw a Speed Daddy exhaust o Ebay and was wondering if anyone has seen or used them? Real cheap so I'm concerned it will be garbage. It is for a 2001 ex

DeeOhEm303

I rate my exhaust a 10!

I installed a Magna flow Single Cat back exhaust system on my 04 Civic Ex and its awesome.
Nice HP gains
Smooth Deep Growl - Amazing Far from "Ricey"
Looks great!

Expensive but you get what u pay for! Satisfied..

Mugen Twinloop axleback with 2.25in mandrel aluminized piping.
Fit: 5. Mugen portion fit perfect, hangars were already welded in place. Had the other piping welded up nice and snug against the body.
Power: 2
Loudness: 2.5. Smooth, deep sound. Louder than stock, but no drone on the freeway. Pretty much perfect in my opinion.

I just installed the cat back 2.25" system from DNA motoring. It has a rolled 4" tip which I really like. The issue I encountered was the noise level, the droning drove me crazy! I had to go back to my mechanic and had him install the stock resonator and pipe. Now it has a nice rich deep sound which is not too loud or ricey and no droning. Also, it was all stainless steel but I wanted to be different so I spray painted it with 2,000 degree special matte black. I used two different primers, first an adhesive promoter (clear) and then a 2000 degree primer (grey). These products are for automotive use, not for grills and stuff.

Could you get a sound clip of your system? I've been thinking about getting the DNA system but I cant find an exhaust clip anywhere.

SammySC

Ok I will try to get a good recording. I tried with my iPhone and it really didn't sound accurate at all. Let me see how I can record with something else and I will upload.

Spec D Tuning $110 special catback exhaust- 2.5 inch piping, 4 inch tip, standard steel.

Fitment- 3.5. It doesn't fit as well as the stock one. I had to bend the heatshield under the car slightly to keep it from rattling, and the pipe hangs down a little. Really quite good for the price.
Power- Honestly not really sure, the car is an LX that I put a VTEC engine in, so the stock exhaust was too small for the engine. But when I installed the new exhaust, the power difference was amazing. The engine literally felt like it gained an extra 2 cylinders! The difference would not be nearly as big if it had an EX exhaust to begin with though, so for me it was 5, but I'll say 3 if you had the proper exhaust to begin with.
Sound- Too loud! It's too loud and it drones badly even at a steady speed. The dam thing never shuts up. It's slightly quieter than no exhaust at all though, so 4.

3" pipe out the hood!

Not finished yet but going to make my own teardrop pipe and outer ring to cover my botched hood cuts...

Let's just say i can't run this in the subdivision anymore to acquire tune data...

Thinking of a spec d exhaust or the megan drift spec. Which one is better?

GolNat

iTrader: (7)

Neither. HKS

Do you live in an area with road salt? The megan would probably hold up better over time.

Jvrubio14

no sir I live in California where theres no snow or any need for road salt. I just want a new exhaust something not ricey even tho it's a civic.
