Aftermarket exhaust for the CX-5?

[CX-SV]

Hey CX-SV, do you recall the forum member who was testing the CS exhaust sold it in the classifieds?

It didn't pass the wife-test for him, which spoke volumes to me. That said, I still want to hear an audio clip or see a video with the CS exhaust on.

Yes, I do remember that. I also assume that was a pre-production prototype.

Is it my imagination or did Corksport update the product details since last time I looked at it and now have performance gains quoted?

Maybe somehow I previously missed (or dismissed) the "+7hp" they are claiming?

doesn't address the cx5 still, unless they see the demand on it.

i just want those tips...i don't need the power or sound...

Anybody got the Corksport exhaust on yet?

yeah i do, posting a thread about it right now

i am wondering about that +7 hp gain posted on the cs exhaust. I asked them to present a dyno sheet, but none exists for viewing at this time. I'm curious if that hp gain is throughout the power band, and what about the torque????

Most aftermarket equipment manufacturers and tuners will quote peak horsepower increases, wherever they may occur. Without seeing a dyno sheet it's impossible to tell how it affects the power delivery. However, being a catback its design goal is probably more focused on sounds rather than performance.

http://autostyle-usa.com/?pkey=item_info&i_code=EXE42421340001& This is nice, the onyl problem is that the shipping is a couple hundred $.. I like that exhaust, but you also have to buy that metal plate to replace the oem one, its about 2k for the set and then like 500-1000$ shipping :/

That's ridiculous!

Why would anyone spend hard earned money to reduce performance and increase noise?

I don't care what the manufacturer claims, its unlikely that a new exhaust will show any real gains in power over the stock spec. That's because Mazda already took into account the driveability of the vehicle and fine tuned it. Any hp increases will come at the cost of usable power through the rpm range.

You will be lucky if you can get any where more than 3hp from just the catback...

Never said anyhting about HP increase, or noise because I didn't find (nor was I looking for) that sort of data. And frankly, you don't know what that effect that exhaust has on performance, or noise, unless you've seen a data sheet, tested it yourself, seen a video etc.There is not much really special about the CX-5 exhaust once you get to the flange splitting the single pipe into two. It's pretty generic.

That's ridiculous! Also people spend their hard earned money as they wish. I wanted a GT instead of a sport for example and I paid more for it.

Actually, I was simply asking a question. Specifically, why would anyone want to spend $2500-$3000 (your numbers) to replace a perfectly good new exhaust with one that makes more noise (I don't need a data sheet know it does) and probably doesn't add any meaningful performance. Admittedly, my comment about less performance is an educated guess, not fact. And, yes, aftermarket exhaust manufacturers will often publish before and after dyno charts purporting to show significant performance gains. And these charts are notorious for being inaccurate (especially true for more modern cars that tend to be more optimized to begin with).

Of course, I agree, people are free to spend their money as they wish.

There just isn't a lot of room left for extra power simply by bolting a different exhaust pipe. I don't need to test it to know that.

Why not take it to a local shop to make a custom one?
I had a custom DP done for my RX7 and it cost me $120 bucks when I had it done vs $300 or so for a name brand.

 

[SayNoToPistons]

Most shops are questionable with their stain tubing material, muffler build, and welds. CorkSport is renown for their quality and being that they mass produce said products, the price would most likely be lower than an equivalent quality custom product... Unless you have decent tig welding skills and have access to mandrel pipe benders, etc.

Agreed. And I'll bet that increase is very high in the RPM band, likely even robbing low end torque.
I would bet gains are negligible until 4500 RPM or so, with a small linear curve revving past 4500.
