Haven't seen a group buy in quite some time. Thanks for putting this together!

 

Hmm, very tempting...

 

Hmm, if several people sign up then I will.

 

How about just taking the lead!

 

Gaaahhhh...I just bought this a few months ago! Either way, it's a great exhaust system for the money. You won't be disappointed.

 

It is easily doable... The toughest part is probably getting the hangers out the spacer, but PB blaster will help with that. All you need is a jack and 4 car stands, float the car, and unbolt everything and then put the new exhaust on... DONE!

 

Okay, well as of right now, I am in for just the exhaust. Not the CAI.

Btw, the group buy is primarily for the exhaust... The CAI is an addition.

Do we know what the thickness of the Stainless Steel is? Also, after doing some thinking (lv. 99 in metallurgy)... why is SS304 used and not SS309... aren't OEM mufflers made from SS309?

 

If by chance the factory exhaust is stainless steel its usually made of SS409. We use SS304 as it is a better grade of steel than SS409, but SS409 does tend to expand and contract more easily with heat than SS304. So really, either is a fine choice for an exhaust; SS304 is a little more expensive to manufacture since it takes longer to tarnish. We've never heard of anyone using SS309 for exhausts.

This site states 309 is best used for exhausts

But when comparing 309 vs 304 you won't find much of a difference as far as car exhausts are concerned.

Add me to the list, muffler only.

Perhaps you meant "exhaust only"? You have been added. Thanks.

Sound clip if anybody is interested of the intake and exhaust that I recorded...

:thumbsup:

I'd figured I'll add myself and see what it sounds like when I'm at the dragon. Then I'll go from there.

 

Adding you now! Exhaust only right? Thanks.

 

Is this kit cool for California (CARB certified and all...)?

 

It is not CARB certified in California... Sorry.

 

Wish I waited a few more days... I ordered both a few days prior to this post... Exhaust is amazing, I got the SRI on last night its amazing will be finishing the CAI this weekend. For this price I wouldn't have thought twice well worth it.

 

Thanks! Glad to see you are enjoying it. :thumbsup:

 

This exhaust system isn't a perfect fit for the 13+ CRZs. How many would need to be in on the group buy to get a minor adjustment for a perfect fit on the 13+?

 

We would need (10) 2013's and a car to redo the exhaust on. It would most likely be a 3-4 month process.

 

The fitment on the 2013's isn't horrible. Yeah my diffuser melted a little...and I mean a little bit. You can't see it unless you crawl under the car to look. For all it's worth, you could probably bend the hangers a tad to angle it down.

Also...A good majority of people I know with different cars, bought "higher end exhaust" and they have melting also. It is just something that comes along with modding cars. The car wasn't designed to have a larger exhaust tip. It was designed to fit around the stock tip.

 

I'm not to worried about it since I have a good friend of the family that can help me modify the tip so it won't melt.

 

We are stuck at 4... anyone else?

 

Ttt!

 

This exhaust sounds pretty mean. Meatguy has it and pulled up next to me at a restaurant and people were asking him if it was K-Swapped.

 

:thumbsup:

 

Would the exhaust fit on the Aem midpipe? As far as i know, no other exhaust would bolt onto aem midpipe, maybe this one?

 

Do you have a picture of the AEM midpipe you are referencing? Thanks.

 

I don't think it would, BLF exhaust has its own style, so swapping exhaust parts won't work.

 

If it was really something you wanted, you could always cut off the flange and weld on a different one

 

Heard this in person on meatguy's crz. I have a cvt too, i want this now!! On my list of things to buy next summer Already spent enough on the crz this year.

 

:thumbup:

Looks good!

In the cabin is not bad at all. The deepest tone you will hear is between 2500rpm-3000 (possibly upper 3100). You can carry on a normal speaking conversation between you and a passenger.

That's exactly how we designed it, quiet when you need it to be (you can still take Grandma out to dinner ), and nice and loud when you ROMP on it!!

 

Just for reference...this is what it looks like with a JDP diffuser. You can see much more of it vs stock diffuser. I personally like that it it sticks out more now.

 

<Thread derail> Any melting issues with aftermarket diffusers? I took a heatgun to the underside of my stock diffuser and bent some of the material away from my BLF tip so it wouldn't become a gooey mess later. As much as I want to get one, I'd hate to screw up an aftermarket diffuser trying to prevent the same issue.

I do like the sound of the exhaust. Forgot to ride with someone that had it installed to see how the cabin tone was, but judging from the outside it should be good.

Its definitely louder and deeper than stock, but its not too bad. I like engine sounds so it doesn't really bother me. There is a certain frequency (for me it's around 3-4k RPM) that seems to cause a lot more resonance in the cabin, so it "feels" louder if that makes sense. And now that Art mentioned it, I would have to agree that the BLF does try to mimic a K-series sound.
