So after the meet in Dover I decided I love the look of ISS exhaust. Went to order online and they sent me an email that the exhaust was discontinued. Does anybody know of a exhaust option that changes the tips like ISS does. Or has anyone added tips to a Joe Z exhaust? Or ideas about custom?

 

ISS has two versions. QES and DES. I'm not sure which one is discontinued, or both for that matter. Joe Z/Performance Tube Systems exhaust has been a forum favorite. Many run it alone wihout any headers, and it sounds just right- a deep growl but hardly any drone at idle. Borla still has an exhaust available, although it's not as popular with the cats. A few have customized the stock system. In terms of the exhaust tips, you can do what FIGS engineering did and remove the tips to reveal the exhaust exit. Personally the quad oval tips aid in defining the F, and IMO it looks right with the car. Best of luck!

 

I was gonna go custom before I decided on Joe Z and shop near me was gonna build one using Flowmaster tips which I believe are similar to ISS Forged but I could be mistaken. When I added up the cost of theirs I just decided to go with a used Joe Z that I found on here

 

Thanks for the quick replies. I will spend some time searching today.

 

We don't have any exhaust suppliers for the ISF in the UK. Has anyone exported to the UK?

 

Joe Z should start making his exhaust with tips as an option.

 

Borla's cat-back exhaust does not have cats.(Similar in setup to the JoeZ exhaust.) This is by far the more popular of the Borla exhausts. They do also have an axle back exhaust, although it has been reported to drone fairly bad.

 

I watched the video of the meet and I like the iss des exhaust. Shame they have stopped making it..

 

Does anybody know why they stopped making it? That's the only exhaust currently with aftermarket tips...

 

It's a shame they stopped making it. I know that they had an axle-back in development which also replaced factory tips but a few months ago some of us noticed ISSForged are no longer vendors on here. I think their CL name was Fitment Factory.

 

Someone jump on this quick.

I'm guessing the RMI scoops have been discontinued as well?

 

I emailed the company and they are back to making only about 30 systems a year. However they quoted me a high price. So I guess its back to the drawing board for me.

 

I'm glad I grabbed my ISS forged exhaust before it got discontinued. Best exhaust IMO.

 

Is borla a good choice?

 

yeah^^^ borla and joe z are prob the most common. both make a solid 15-20 wheel hp, borla has a touch less drone and joe Z sounds a little meaner
