I've decided my next mod will be long tubes and o/r x with a dyno tune. I'm between stainless works and kooks right now. Which would you choose and why? Also, what are people's experiences with other brand long tubes on these cars?
Why not American racing?

I'm running Stainless Works 1 7/8's w/ catless XP. Here is a before and after dyno graph. No retune.

So you don't have a tune for the long tubes? I'm curious how much more power it would pick up with a new tune. I can't tell from the graph but what were the before and after numbers? How was the install?
Tuner said there wasn't a need to retune for the longtubes.
First run was before the LT install in green and it put down 394/386 (88.35 F, 29.30 in-Hg, 59% Humidity, STD: 1.06).
The two other runs were after the LT install and had basically the same results. It put down 424/404 (76.62 F, 29.22 in-Hg, 46% Humidity, STD: 1.04)
I had Woodbine Motorsports in MD do the install.
I have bassani long tubes, o/r x-pipe, and cat back. I really liked the way the videos sounded online. Also i have a friend who has a 04 Mach 1 with a full bassani set up and loved the way his car sounded. Got it installed last week. I really love it. Its whisper quiet at idle, but it really screams once you put your foot on the pedal. Paid like 860 for the long tubes and 910 for the the cat back.

This is only correct if your a/f ratio is still safe througout all kinds of driving. I'm gonna bet this $5 I have in my wallet on that it isn't. You are betting your $5k+ motor on it still being ok.
Who is your tuner? That doesn't sound right to me. I plan to get a dyno tune after I install them to get the most out of my car. Those are good numbers. I'm hoping for 430-440.
