I have driven my fair share of cars and I got to say Lexus has created a hell of a platform. The M3 is a great a car but my next car will be an IS-F. All I'm saying is that I believe in what Lexus has done and want to help expand the ability of this car.

Every time I get in an IS-F I never want to give it back. Can't wait till November!
I agree with you completely. Love every minute of driving this car, Lexus did a remarkable job. You get to see that the more and more you drive the car. When do you think headers can become manufactured? I see your exhaust development went quick...real quick.

The headers are in the beginning process. For now it's to soon to tell. Hopefully it will be quick and easy but we all know it's never like that.

We have been very lucky to meet cool people that are allowing us to develop our product line. We are also very grateful for all the support on this forum. The ISS Edition IS-F is well on it's way. It is going to be a true M3 killer.

Thanks Guys!

coming from most IS-F members THANKS!

So I pull into Wal-Mart the other day and drive past a group of taxi's and they're all standing outside their cabs. I'm in manual and roll past at about 30ish. I park and start to walk in...all 4 of them walk immediate to the back of my car and stand there smiling talking about the exhaust. They didn't even peep at my $6500 wheels!

That's whats current with my exhaust.

I love this thing!

....wheels and tires...well worth it, great wheel manufacturer...3 piece forged...anyways...
they could have been forged diamond wheels and these guys would not have noticed, they were so caught up in the exhaust.

Your sig says your in Aventura? I'll be at the mall on Friday doing some work. PM me and we can hook up.

Those all BLACKED out tails are horrible too, to each his own I guess....makes the car look cheap like those old school GTS headlight and taillight covers!
Not an ISF owner but everyone has an opinion.

Now that I've looked at these pics several times, I'm gonna have to agree with 4play. It doesn't look that great to me. It doesn't look bad but it's not as classy and this is still a Lexus.
It would have been better if the 2 tips were side by side. In this position, a more oval shape would be better, closer to the stock shape. Sitting this way, these big round openings look kinda weird to me.

I still have to see it in person for a final judgement so I may be taking back what I just said.

In the end I am very happy to see the aftermarket responding to this car. As more product is developed, maybe Lexus will get off their butts and produce more vehicles of this type. I'd love to see an ISF coupe (fixed roof) and a GSF.

It'd be real cool if you guys could shoot for a design that enhance/brings on more torque lower in the rpm band and not go for a totally high peak rpm/HP number...gonna be a real tight fit in there.

Someone just needs to make an exhaust tip that is in the same shape as the opening.

For example:

Any issues with heat on the tips yet? it looks like they get _very_ close to the rear bumper itself? Just curious... I'm really liking the exhaust (pictures)

3 weeks of fairly heavy driving and no problems to speak of.

These tips have a heat shield so there should be no problems.
