For those who wants to compare:
I will send sound clip when this coming weekend. However, listening to the clip of the Magna Flow, sound just like my TRD Cat-Back on my 05 V6. It is a lot louder then the Borla.
For those who wants to compare:
It the Borla kit the fits directly into place where stock exhaust located. It is the same clearance as the stock exhaust. For me, did not want the roar of the Magna Flow as this T4R is mostly a road cruiser with only about 20% running on trails. From my experience, the Magna Flow is as loud as the TRD Cat muffler with 18" canister. At this point, I am experiencing better throttle response, less downshifting from OD and running at 1MPG gain over stock system. Noise increase remains minimal. This were my goals for installing the Borla. Will send a video this weekend.

For those who wants to compare:
Do you have any data? Documentation, response times of before and after or dyno runs? 5% efficiency gains overall is a huge number.
So 1Engineer, data is solid after 600 miles, realizing 1MPG increase on road. This in in varied weather up here, some mornings in lower teens to upper 50's. As a rule, I drive my vehicles and don't beat on them, but will tell you the throttle is more responsive and it pulls hills better at +65MPH with less downshifting from OD. As for cost return, didn't really worry on cost as intrinsic value is working on my car and satisfaction from the work.


Here is the old one out.
This right here was the longest part. Spot welded on the nut and we didn't have a legit lift, just a jack so we didn't have enough room to work the whole length of piping out. Hence hack sawing it and turning it into a few pieces like the first picture.
photo bucket is being dumb and not uploading video. i'll try later.
Excluding time spent sawing, I would say pullling the old one out and putting the new one in maybe an hour, hour and half tops.
wow the old one put up a fight :driving:
It was a giant pain in the ass. There was no good angle to cut it from and then the first blade went dull
Did you use a Sawzall? The carbide blades will make fast work of it.hwell:
I know this is after the fact but, most auto stores rent this out for free:

It's an exhaust pipe cutter, basically a long chain of cutting wheels, much easier than a hacksaw since it's a whole bunch of wheels cutting around the entire circumference at the same time
Though it if that much of a pain to remove myself, I'd probably just drive to the local muffler shop and give em 5 bucks to chop it off for me, lol. That's insane that they would weld the nuts on from the factory, geez!
