Geneva, you have the Joe Z now and just purchased the Borla? I would really like to hear what you think about the differences. I love the Joe Z but it would be good for others to hear

I'm referring to the tips coming out of the mufflers, not the oval ones mounted on the rear garnish.Both Borla systems utilize the stock F tips. I'm confused by your statement by your above statement concerning the tips

I do not have the JoeZ but had a chance to do a ride along and hear first hand from outside drive-by to interior at various speeds. Spoke with Chris at Borla and he convinced me the axle back should be what I'm looking for. Ordered from Speedfreaks and expected ship date is 5/18. Will keep everyone updated with progress and results.

What arguments did Chris use to persuade you to go with the axle back system? It has always been my belief that a V type engine should be equipped with a well designed dual exhaust with an H or an X pipe. It is my opinion that this is critical on a V8, V10 or a V12. I don't understand why Lexus designed their "semi-dual" two into one into two exhaust system. The axle back maintains this configuration, but frees up some of the back pressure with lower restriction mufflers and a better flowing rear Y.

Guys,
I installed the Borla Cat-back exhaust system plus x-pipe today, the offroad version. I was thinking at first, oh damn what did i do and thought it would be rediculously loud but no.......and DAAYYYYUUUMMMM does it sounds good. Pretty sure that Borla installed my own personal cheerleaders in the pipes. It sounds deep and throaty. I stuck my car on the dyno before stock today and it produce 344rwhp and 318 torque, after it produced 354rwhp and 326 on torque, it was a hot day down here though and not much airflow. I forgot the printouts for the dyno but will pick them up early on in the week when i go back to get the k&n system installed.

finally an independent dyno on the borla off-road system. doesn't compare in gains to the joe-z system tho as the borla system added about 10hp compared to 22hp on the joe-z. maybe if the conditions were better, you would have seen better than the 10hp gains....
i'd be really curious to see what the k&n does. you should do a pre and post install dyno on the k&n also

I would really like to see the results Mateo. Thanks for posting up that you installed it and had it dyno'd and I'm glad to hear you like it. Interesting you only got 10hp off the system, what were/are they claiming out of curiosity? Weather could have played a small role in the gains

Were these SAE corrected results!? I can't believe it only gave you 10hp considering it's almost identical to the PTS JoeZ series. 2.5" tubing, x pipe, high flow mufflers etc. Something doesn't sound right. Also not sure how many runs you did on the dyno buy typically the 3rd and 4th consecutive run will yield the highest numbers. So if you took your highest baseline and compared to only your first run with the new exhaust I could then see where you only showed a 10hp gain. Hell my first run on the dyno with the new exhaust showed only 3hp gain, but by the 3rd and 4th runs I was at the 20 hp gained mark.
well i will run the dyno again after i install the k&n since we already know what it runs after the Borla it won't be hard to figure out. I am not sure however what Borla was claiming. I was showing a very low air-fuel ratio, anyone else had problems with this? Not usre on the numbers exactly, will get them when i go back Monday.
Funny that you say that because i actually pulled 10hp the first time, the second was less. Like i said, it was very hot and humid today here in south
florida and they had fans blowing from the front but not enough to do anything, not sure if this could have made a difference.
i was saying run the dyno before and after the k&n install just because your numbers with the borla seem a little bit low... if you compare to those numbers, it might inflate the true gains with the k&n. would be nice to get a new "base" before the install.
True, will do.

Everyone recommends getting the Joe-Z exhaust because majority are saying that it makes the car sound like a real muscle car v-8. BTW what do you mean ricer sound?
