Sweet, thx for the replies. I went ahead with the installation, i helped my mechanic install them and it took us 5 hours since our shop is not exactly designed for exhaust work. We had to do it on the floor and "pain in the ass" is an understatement. The car sounds amazing now and seems that it got louder and better the day after. Here is a video of it, right after the installation.


Stupid me, i forgot to mention that the car is a 2005 Mustang GT with JLT CIA, under drive pullies and 93 octane Dyno tuned. How necessary is to tune it right now? Its gonna cost me and additional $200

I noticed a big difference in the sound so far. performance wise, hard to tell but not fair to say yet before tuning it. Lets just say, people stop their conversations and turn their heads to look at the car when i am driving by. I am Loving it so far, and so glad i went ahead with it :)

You should get your tune adjusted for the cat delete.

Sounds nice. Are you running stock mufflers?

no sir. I have flowmasters. It was the first thing i have ever done to the car, a week after i got it. They basically just cut the stock mufflers and welded the flow masters 40s series on there, nth fancy but was cheap way to get outta the stock sound.

The video sadly doesn't do the car justice, bad camera.

I will get that tune as soon as possible, can't wait to run it. I do 13.2 @ 107 in the quarter, you think its possible to break into the 12.9 with that upgrade?

Sounds good man!

Thank you, will post a better video with an HD camera after the tune :)

Now THAT'S how a Mustang should sound! Nicely done! You should definitely have the tune adjusted to make the most of the headers and cat delete.

Thank you, iam loving it. tune will be done next week, my engine light just came on and my mechanic said it was because of the cat delete, so gotta do it ASAP.

Here is a better video of it, closer to the real deal :P
