Would you be Interested in a Down-pipe for 09+ TSX?

A company that would like to remain anonymous at this time thats on this site would like to see how much interest there would be for a down pipe from the manifold to exhaust (essentially hi-flow cats/cat deletes). Weapon- R makes one at this time for the R18 on non-SI civics. It yielded 8hp. Please Please Please answer the poll while also starting a discussion. The company will be watching the thread. This company is very respected for making exhaust components for other Acuras. I can't answer any questions on price etc as he doesn't even know that himself how much it would be.

Here is a pic of the R18 Down-pipe. Will be similar on K24



Take care Des,

i am a car noob, exactly what does this do to yield extra performance gains? is it compatible with a cold air intake? what are the downsides?

also, price will definitely be a big factor for many i am sure!

although you cannot comment on the price of this exact piece, could you give us info on how much it costs for comparable vehicles such as a civic or an accord so that we can get a ballpark figure?

You know, looking at the entire exhaust system, I pondered the idea of moving the cat where an exhaust manifold would normally exist to somewhere farther down the exhaust system. Say where the resonator in the exhaust system existed. Just thinking out loud.

I also wondered if we could move to a head that would accept a normal exhaust manifold and see if we could see any gains from that (more money involved and start to become smog illegal).

I'm interested overall, but I'm also looking at a bigger picture. I wonder what setup RTR is running.

I honestly don't think the market is large enough. Aftermarket support for the CU2 TSX is already very slim as it is...there has hardly been a demand for a new intake let alone entire manifolds/ECU's/test pipes. There is no demand whatsoever for a test pipe or entire exhaust, let alone a down pipe. Whichever company you're referring to anonymously in the OP would probably lose money on this.

The only other car that the K24Z3 is found in is the 08 Accord...and I'm going to assume that the market is even more slim there. Unless this company could apply it to other models, I don't really see a use.

I was pleasantly surprised to see how large the accord community is and the aftermarket support it has. Especially the aftermarket suspension availability. I don't know enough about either chassis to know if the same down-pipe would fit, though.

I think support for the CU2 is slim right now since it's such a "new" car, its really a "If you build it, they will come" thing IMO

Again the initial post states the R18 gained 8hp. Id Expect 5-10hp at least on K24. The Megan pipe is 150.00 msrp.

The market is big at . A company just finished an intake manifold for the K24 they are pushing there. I'm sure they'll be in the forum soon. The k24 sells better than v6 if you forget. I posted this same question there for this company. The K24 could/would def benefit from more low-end. The TSX was 4cyl only almost the 1st 2 yrs. Then you have the Accord LX, LX-P, EX,EX-L sedan's as well as LX-S, EX, & EX-L which can all be had in 4 cylinders. I think even more so the TSX will gain more power than the Accord being that it already makes 11hp/9tq more than its cousin. If you'd like to add to the potential of a cat-back exhaust, vote yes.

I am very interested in this. Been waiting for a while since I don't really want to go custom. I don't necessarily think because the 2G TSX is newer since there is more support for the 4G TL. It's just that there is just less interest.

Looking forward for this to follow through.

yeah, less than 200 sounds more than reasonable.

and as a noob quesiton...i always thought downpipe is for the turbos...what good does it do for our car? is it like the intake, where it free up air flow?

We have a downpipe only because we dont have conventional headers where they go from the exhaust ports of the head down to the bottom of the car.

I would be interested. On my old Civic R18, I had the Megan downpipe. Was nice. Not a crazy difference but good mod overall.

Not really interested. With a stock exhaust and no desire to change it in the future (I can't have a loud daily driver), this would be rather pointless for me.

Downpipe works with stock exhaust. Would add needed torque. Find out info b4 you judge..lolol...

Icrease exhaust flow. The stock pipe off the manifold has all the cats. The down pipe is essentially a hi-flow cats on a larger diameter pipe.

Needed torque? It's his and 99% of other TSX owners DD. It's been popular since 2004 and has only had a torque bump in '09 of, what, 5ft. lbs? There has been a general consensus year after year that the motor is peppy enough for DD duty.

Agree, this car has the perfect amount of power for a daily drive .

Don't try and be an asshole.

Point is, this car is far from fast, and that's not why I bought it. If I wasn't planning to go all out with the entire exhaust system, its pointless for me to get this as well. Even if it were to produce a few extra horses and a minor amount of torque, it's just not something I'm personally interested in doing to this car.

Just because it doesn't appeal to me and my needs, doesn't mean it's worthless to others.

Wait so theres an intake manifold in works too??? I'm interested in both but cost would be the deciding factor of course. I look at modding as a hobby and having something a little bit different as everyone else. Not expecting to have gobbs of power from any bolt on part, if it makes power great if it looses power or remains the same then I won't get it. The main thing for me is the time spent working on the car in the garage and like I said looking/sounding/being unique.

I did start a thread awhile back looking to see if any one has any ties to Skunk2 to see if they were planing on coming out with a cat back for our 2nd gen and got no decent reply from anyone on here or from Skunk2 for that matter. Would that happen to be the company??? Have to ask.

I'm still noob to all this stuff about engine mods but I am always interested in new things and with this, I am definitely in! Except for me, I live in Australia so I might not even be able to get it but nonetheless, I'd like to see how this goes.

This poll is up for 90 days so please keep the discussion going so it with give 2nd gen tsx owners an opportunity to see the thread. If anyone has any question, i have a very mechanical mind and will give you estimate of what should be expected from this piece.

so lets say you have a CAI. Then you are increasing your emissions numbers...and then you add a downpipe on top of that... will that cause you to be well over standards? i am just pulling this out of my ass, someone with real knowledge feel free to step in


Quick Reply: Would you be Interested in a Down-pipe for 09+ TSX?
