Who makes the LOUDEST exhaust?

[bngl3rt]

Cruising in my car yesterday I realized I could hear all the Beamers, P-cars, F-cars, even motorcycles cruising nearby, but I couldn't actually hear my own car. This obviously won't do.

I am currently on CT headers, stock exhaust, and this is California so I can't really take out the cats and switch to "test pipes" (cough cough)

Just don't use a muffler at all. Come out of the cats and go to tips. It's super lightweight, super loud, and super cheap. :biggrin:

Nice! Is it reversible or would I have to buy a spare stock exhaust to hack up?

my car is pretty loud with ct headers and pride v2... but the lamborghini murcielago's in town still drown me out. it can be louder with testpipes, though. i don't recommend doing what TURBO2GO said because it will sound like crap. of course, that is all subjective and some people do not share in my good taste.

Lambos are allowed to drown me out, but I draw the line at being quieter than a BMW M3.

I get it, Japanese cars are designed to let people who are packed into dense cities get some shut-eye...

Pride V2 and Test pipes will take care of that....super loud.

I have Cantrell Headers, Resonated Test pipes and Ark DTS exhaust and it gets really loud as well.

 

[junior40er]

and I live in cali also thats why I keep my cats to bolt on (15 minute job) on smog days.

So the Pride V2 w/ tp is louder than the GTLW with tp?

 

[bngl3rt]

Let's assume that when I get pulled over for my car being too loud, I don't want to get caught without my cats on...

Just have a muffler shop do the pipes for you. Go into some resonated tips. It's easy to sort of see what it sounds like. Remove the muffler and start the car. With pipes it'll be slightly quieter and more refined. It's not a big investment if you didn't like it, and it will definitely be loud. The cats are essentially your mufflers.

Then you don't want it loud if your worried about being stopped. But you can run HF cats. Give POKNOW a pm. He has a low mile V2 for sale. He's really not wanting to ship but you may convince him. I would check classifieds here for some used HF cats or pm Brian@Prospeed for some. Keeps you more or less legal and still plenty loud enough.

Or buy these.

I had that before I had a muffler shop fab up some test pipes for me, great sound w/ my Comptech. That reminds me I need to sell mine.

Fair enough. Stock exhaust is probably a big part of my problem

 

[TURBO2GO]

I guess you are not looking for a low noise floor? You want a super loud exhaust and you want a DSP in your car to fine tune the acoustics? LOL

I guess it would be easier to tie a synth/sampler to the tach over ODBII and use it as an input to the DSP so I can control the exhaust volume...

Your stock muffler is holding you back ALOT.

The B&B tri-flow muffler has a great tone and is quite loud even with cats. ALso has no drone.

Best muffler imo.

I have a hard time believing a cop is going to get down on his hands and knees to look under your car and search for the cats which he most likely has no idea where they might be. He might send you to a ref but he isnt going to waste his time trying to find the cats on your car.

Meanwhile before you go to inspection you just switch in the cats and oem exhaust.

 

[docjohn]

for loudest honors you will need to delete cats,once you do anything called a "race" exhaust will do,the taitec jgtc is loud,as is kakimoto. I think you will enjoy your decision for about a month:wink:

I agree, stock exhaust on the NSX & M3 is too quiet... definitely not suited to the car's sporting image. Honda and BMW could use a lesson from AMG, their stock exhaust are done pretty well. IMO the V10 M5/M6 should have came stock with Eisenmann exhaust

 

[Honcho]

Kakimoto is the loudest, most ridiculous exhaust I have ever heard. It sounds like a JDM end of the world.
