Re: Turbo Exhaust choices Mongoose/japspeed/other
Berk on mine, with Berk Decat. It's loud. Much louder than I thought, given the reviews on here. Good noise though.
Drones something awful at an indicated 70mph. Fortunately an indicated 70mph is (according to the GPS) an actual 62.5.. At a GPS-indicated 70 all is actually quite serene!
I had a japspeed on my previous turbo. It had a huge hole in it. THAT was loud. Gorgeous noise. Sounded like a NASCAR.

Now that is loud!
Good thing about the SARD is that there is no drones at any revs, just great for a daily and the highland drive

True. At a speedo 70mph (more related to the rpm though) the Berk does drone. Get it up to 80 and it's very quiet._Al_ wrote:Berk on mine, with Berk Decat. It's loud. Much louder than I thought, given the reviews on here. Good noise though.

I've welded an extra silencer into the mid pipe of my Blitz NUR R, it is a fair bit quieter now and has had little effect on the performance.Lezz wrote:Blitz Nur Spec with the baffle fitted would be my choice for a 'quiet' exhaust on a Turbo - obviously without the baffle they are much more fun & the baffle is easily fitted and removed dependant upon the occasion - win win!!

Re: Turbo Exhaust choices Mongoose/japspeed/other
Holy thread resurrection...
I have a mongoose with no cat on my gen 4 turbo. The drone is awful!
Unless I wait for something decent to come up 2nd hand, I don't see any other option than to get something custom made.
Any advice?
Andy

Re: Turbo Exhaust choices Mongoose/japspeed/other
I know bungs reduce noise but do they reduce drone as well? Andy

Re: Turbo Exhaust choices Mongoose/japspeed/other
Had a Japspeed before I got the turbo conversion done. It was far too loud but after putting bungs in it it was bearable.
Running a berk system now which is pretty much perfect.

Well those are my principles, and if you don't like them... I have others.

Indeed.
Another alternative to the custom route unless a twin exit is a must have.

I should try bungs first to see if they do actually remove the drone.

Re: Turbo Exhaust choices Mongoose/japspeed/other
Paul at TCB managed to get me that HKS exhaust a few months ago - worth a shout if you decide to go for it. Really high quality item and not noisy or droney at all.

Re: Turbo Exhaust choices Mongoose/japspeed/other
Just one caveat. The 409 in the product title refers to the material used in the bulk of the system (except the back box and tail pipe) - https://www.hks-power.co.jp/en/product/ ... index.html
It's nowhere near the quality of SUS304.* My Blitz Nur-Spec R was on T2 when I bought it, so is at least 11½ years old. Only a few tiny specks of surface rust around a couple of the welds.** Still none on the pipework. I also have a HKS Super Drager so can compare the two.
* https://help.summitracing.com/app/answe ... s-steel%3F
** The quality of the welding on the Nur-Spec is streets ahead of other exhausts imo.
