Installed resonated Magnaflow resonated tips today.
I was getting tired of scraping the ground with my exhaust tips on my Borla exhaust (Borla 11729) and decided to take advantage of the sale Amazon was having on Magnaflow products. I picked up 2 oval resonated tips model 35174 and put them in place of the carbon fiber tips on the rear. While the car was in the air, I had him replace the small muffler after the cats and y with a straight pipe. The shop only charged me $70 for everything and did an awesome job. I couldn't be happier with sound! I'll try to post a sound clip after work. Here are the pictures...
Before
Cut off the small muffler
Straight pipe installed
Old tips removed
After
Over 200000 miles and still modding!
Bonus pictures of a cool boss 302 the shop was in working on

The Borla exhaust I have was essentially a muffler delete. Borla just used stainless steel piping and a 4" resonated tip. They stopped making this system some time ago. It's pretty aggressive and weighs a lot less than the stock mufflers.

It's really not that bad as long as you leave the other resonators installed. Here is my old video right after I installed the borla. Everything else on the exhaust is stock. Please disregard the background music. Don't know what I was thinking!

Maintain PM'd me the following questions and I felt others may want to know as well so I hope he will not mind my answering here:
"I remember reading one of your exhaust post about x-pipes where you stated that the stock system functions as one big x-pipe and is very well engineered. With that statement, I concluded that it would be unnecessary for me to remove most of the stock exhaust just to put in a smaller x-pipe and run all new pipe to the back and lose low end power. Removing that small resonator made more sense to me since it seems most people (including me) do exhaust mods to gain more sound seeing that power gains are negligible. Just wanted to hear your input on my thought process for this exhaust mod. "
It looks like the shop replaced your center resonator with a 2.5" pipe. The stock resonator = a perforated 2.36" pipe so the 2.5" is a good choice for an upgrade. Not sure about the transition back to the second Y pipe leading to the rear duals and the performance may not be noticeable... may just be louder and possibly create droning. What do YOU think of your change? Power? Sound? Droning?
I do recommend keeping the stock front Y pipe which you did. Removing the resonator and mufflers will obviously make the car louder and I wonder about your driving impressions? Louder usually makes a car "feel" faster but is yours any faster? Removing also reduces weight which improves power to weight ratio as long as power does not drop.
Weight is one of many good reasons to keep pipe size as small as possible as larger pipe size weighs more.

I don't mind one bit. Maybe someone can benefit from this information. As far as performance gains are concerned, it feels no faster than before but it doesn't feel like it has lost any power. My goal was a throatier sound which I feel I've accomplished. The resonator that was removed made the exhaust have a more subdued tone. Now it has some bark throughout the entire RPM range. It is a touch louder but it seems to be getting a little more mellow as I break it in. I love the way it sounds and have no regrets.
