If they scraped the project, it's prob because they were obnoxiously priced. $2,250 for an exhaust system that's going on a Lexus? Really? Not knocking the quality or class of Lexus, but one could get a descent exhaust system for a Ferrari at that price. Guys, take your car to a reputable custom exhaust shop (not meineke) and have them swap out your stock mufflers with Magnaflow's, because that's what ISS used. I'll post some pics and a sound clip when I get mine done.

NO DRONING! Sweet sounding system! I can feel the difference, much more responsive.

GSGUAM, can you please post a decent sound clip video?

And as for everyone saying its expensive, its hard to say unless you look at the qualify of the welds and hear the sound.

I plan on buying it out after the 3yrs, so why not? It's bolt on, and I can throw it on my garage lift and swap it out.

What kind of muffler was used. Did you get the exhaust system for $1550 as initially priced or the higher price of over 2K?

Raising this thread back from the dead! Those who bought the iss forged exhaust, how is it now that its broken now in? Is it worth the $2200 they are asking for?

Sounds a little too steep for 5 WHp gain.
