My Frankenstein Exhaust Creation

After installing Richie's j-pipe and test pipe with my stock exhaust, I just wasn't happy with how quiet the exhaust was still. I decided to start looking for an alternative to the usual bolt on cat back options since A) They're expensive and B) I usually like to try something different and unique.

Stock Exhaust before Frankenstein Exhaust



A few weeks ago I picked up some Acura CL Type-S mufflers off of the Classifieds, so the original plan was to I have a muffler shop cut the stock mufflers off, replace with the CL-S muffs and maybe delete the stock resonator or have them custom bend up some tubing for me to the CL-S mufflers, which could get expensive so it was the 2nd option if the 1st option wasn't to my liking. As luck would have it I came across an ad on Craigslist for a modded 05 Accord 6spd looking to swap a custom exhaust for a stock exhaust for free. The mid-pipe section is 2.5", no resonator, and goes down to 2.25" at the y-split to the canister mufflers. I'm pretty sure they're just some of those huge grapefruit shooter crappy eBay mufflers. And let me tell you, with the j-pipe and test pipe on it's freaking LOUD!!! I listened to it on his AV6mt before agreeing to the swap and honestly it sounded pretty good, wasn't too loud and had a decent tone to it, but on mine with Richie's stuff it's really obnoxious and drones like mad. I've been driving like an old man shifting at 1.5k RPM because I'm pretty embarassed to drive around with it on, but I really only got it for the piping anyway so it'll be changing soon. I'm planning on spraying the piping with some hi-temp silver or flat black to cover up the surface rust on the welds and just to make it purrdy. Here the monstrosity:





And today hopefully I'll find a shop to put these on:



I think once the CL-S mufflers are on it'll quiet the exhaust down to the level I'm looking for but still be a much better flowing system than stock while maintaining a relatively stock look with the OEM CL-S mufflers. If it's still too loud after the CL-S muffs I might have to go back and have a resonator installed in the mid-pipe section. So what do you guys think? Think it'll sound good? I really want my car to sound like a G35! <-- Kidding. I hope it works out and I can shoot a picture and video of the exhaust with in the next few days. I just figured I'd share my creation with you guys. Wish me luck!

Right now im running two Civic Si mufflers, pretty interesting setup, just need to get a glasspack to remove some of the rasp that it sometimes has.

The piping was free since it was an even swap for my stock exhaust, so it was mainly a cost saving thing. I know the canister mufflers suck, like I said, I didn't care about them since I had the CL-S mufflers.

Nice, you're looking to do the same thing. I thought you have a 6th gen, no? I know there's a few 6th gens with them but I haven't seen any 7th gens yet.

Well, I just went to the local Midas and had them do it. Let me tell you they sound fantastic! I went without a resonator. They had to hack off the piping from the y-split since they didn't line up with the CL-S piping but what ever, it works. The only issue I have is they aren't exactly centered in my exhaust cut outs. I'm going to have to figure out a way to fix that myself because it didn't seem like they could get it lined up perfect and I'm anal about that kind of thing. I think maybe once I get it off I can mess with the hangers and get them a little more centered.

first off, those mufflers need to go PRONTO! lol . other than that, for being custom piping with crush bends, it doesnt look half bad from behind. trust me, ive seen some really unsightly custom work done from the Y to the mufflers. just clean them up, lightly sand them and paint them with some really high temp ceramic paint, in the color of your choice.

dont even bother messing with the hangers, cause that wont work. looks like they welded them in cockeyed. have them weld some new hangers on the cl-s muffs (unless their oem hangers will fit the 7th gen, which i doubt) then, istall them, making sure their even on both sides and centered in the cutouts. then, they can adjust what ever needs to be done, before welding them in.

oh, and you might as well install a small resonator too. the cl-s mufflers will quiet your tone down a bit, but it will still have that "ring a ding ding" raspy sound you here on alot of civics.

Yeah I was thinking the same thing Sean. Mike with the 3.2CLS that Siggy got his flywheel from said he has straight piping on his CLS mufflers with headers and it sounds sort of liek a stock NSX, not sure if thats a good thing though

Ha ha, too late guys, you must have missed me saying I already had the CL-S mufflers installed this afternoon. I just haven't snapped a picture of them yet. Those canisters were pretty off too though.

The CL-S mufflers had the hangers in the same location, I just think that the muffler itself is either slightly longer or wider than the AV6 muffs, so when I asked him to center them more he said something about not having enough room. The looked more centered when the car was on the lift vs. when it was on the ground. I'll shoot a picture when I'm out of work. I'm totally happy with the sound without a resonator though. Sounds very clean, not raspy at all, and it's just slightly audible in the cabin, not even 1/10th of what those canisters were, no drone at all. I'll try to get a video clip of the sound, too.

Okay, got some video clips. I know the second one is dark so you can't see the set up but it's dark when I get home from the gym. I want to get the piping painted first and try to straighten out the muffs before I show it off too much anyway. Hopefully I'll have that done by this weekend. Let me know what you guys think about the sound. I'm just curious what you guys think but honestly I freaking love it and feel like I have a totally new car. I had my radio off the whole way from the gym. It sounds muscular but it's not loud at all and like I said no drone in the cabin and just enough volume to really appreciate it. It's exactly to the tee what I was hoping for and wouldn't change a thing about the tone/volume of it. And no I don't think it makes it sound just like a G35... it sounds much much better! And don't make fun of my plate I'm sensitive.

Thanks! Honestly I was a little skeptical myself. I thought I'd definitely have to go back for a resonator later on but I think that would quiet it down too much. I guess having had a CL-S before this I knew how good the mufflers could sound.

Oh I definitely will snap some pictures soon. I think anyone who didn't know what the stock exhaust looks like might just think it was stock. Of course it'll look even more at home once I get them centered.

Yeah, stock precats. Of course video clips can only replicate sound so well. It sounds great in person but of course we all have different tastes.

Alright, took some shots this morning before heading into work.


The drivers side is nearly centered but still a little off. The passengers side is quite a bit off center.

Do you feel any gain with your exhaust ?? I very like the sound. Do you think with TL-s muffler it can have this kind of sound too?

^ I definitely felt a very nice gain as soon as I put the larger piping on and the CL-S mufflers didn't seem to effect the gain too much, only made things much quieter and better sounding. I'm not sure which year TL-S mufflers you're asking about. The 2nd Gen TL-S mufflers I'm pretty sure are the same exact internal design as the CL-S mufflers, the only difference being the tips. The TL-S tips are round verses the oval tips on the CL-S. I'm sure the 3rd Gen TL-S mufflers are a completely different design though so I have no idea how they'd sound.

That sounds great!

As far as the gains, did you notice any loss in low end with the bigger piping? And how were the gains up top?

I went over my buddies place last night and had him rev it for me while I was standing outside the car and it sounded like music to my ears. Couldn't be happier with the sound. I figured I'd shoot a video of it this morning on my way to work. It's just a clip of taking off gradually giving it more throttle from a start, taking off from a distance coming toward the camera and then just a slow cruise by the camera to a stop.

Thanks a lot. No, I didn't get a chance to paint it yet. I think I might stop by the muffler shop that put them on tonight on the way home and see if they can straighten the passenger side muffler out. If they can it would be better before painting the piping anyway just in case they have to re-weld it in place. I have Friday off from work so I'll be painting it then. I'm definitely going do to flat black instead of silver though for the stealth look.
