KOspeed looks good, I'm interested in that too. Price is pretty nice with all that it comes with.

On my Ultra rev exhaust, after 6000 miles sound hasn't changed still looks new. Now the bad, one hanger snapped off on the muffler. No biggie but had to remove muffler to re weld. Also installed AP mid pipe, sounds great, loud but controllable with the throttle and no or little drone at cruise.

Glad to hear good things about the AP midpipe. Everyone tells me it has a rasp. I just ordered mine... What do you think?

I have Toyosport catback, RB dual res. midpipe and ebay headers and it sounds GREAT!

After hearing other mid pipes, it sounds horrible. I have the AP mid pipe, both on a stock exhaust and my HKS high power. It wasn't as noticeable with the stock exhaust but now anytime I put some heavy throttle at about 3.5k rpms, and up, the rasp comes out real bad. Under light throttle though I never hear it. You get what you pay for, but for the money it is the cheapest and gives the most HP out of any mod.

When I had the stock muffler on when repairing the ultra rev I had the ap rasp (very noticeable ) , from 4000 to 5000 rpm. With the ultra rev no rasp or barely noticeable. Also with the ap pipe no codes set after 800 miles.

Ok, that sounds fantastic to me, you may have just sold me on it.

My Ultra rev crapped out, after 6500 miles a hanger for a muffler gave out and ripped about a 6" section out of the muffler. Repaired once but gave out again. It appeared that it was originally welded to the thin skin of the case instead of the stronger edge like the other side. Something to watch for.
Purchased a Turboxs system and couldn't be happier (Very well made and sounds awesome.).

Just wanted to give a update, I purchased a ebay exhaust around 200 bucks with burnt tips. Sounds awesome direct fit pretty much I think it melted some of the plastic trim area.
