hey guys I've been reading the forum for a while now and need some help. I leased my F when i was 16 and couldn't do any performance upgrades..but now I'm buying it out so finally i can do some mods to it to really make it sweet! My question is where do i get in contact with iss performance because its looking like thats the best exhaust for performance gains? Also i bought a K&n intake but apparently it doesn't have any gains so I'm just going to go with the joez intake and drop in filter. id really appreciate the help!

 

I think someone posted a few weeks back that iss stopped making them but if you cough up like 3 grand they will make one for you.

I'd go with the joez exhaust

 

That is the general feeling. I'd advise the same as streetx. An ISS exhaust, whether DES or QES, will be hard to get right now, especially with the IS F not continuing for the next model year. Joe Z yields some HP and doesn't cost nearly as much. If you go to the vendor section on the forums, there might be some selling Meisterschaft and Borla catback systems. Also, PPE developed an exhaust that is available for purchase. You can find that one from FIGS, also a vendor here.

 

ISS exhaust ftw!

 

Joez exhaust is ur best bet and highly recommended

I inquired about it earlier this year but too expansive after conversion and shipping to Canada. He said they make a run of them 30-35 per year so he might have few in stock. I believe quoted me $3000 with shipping for the latest design where u can remove rear mufflers they are on v band clamps. Checked my email $2795 plus shipping they are now in Houston tx



If you proceed ask for free shipping I'm sure they could do that for you he was willing to knock off $200 so prolly shipping price to Canada.

Borla is a better option $1100 shipped you just don't get the shiny tips that iss offers for extra $1900

By all means it's a nice exhaust so if you want to cough up the dough go for it you will be happy with it.
