Bold statement? yes......but maybe true. also happens to depend on what someone wants in a system. i just want a system that flows enough for my GT2871, sounds good, and doesn't turn my car into a bass tube coming off the freeway at 2800.
I've had 7 exhaust iterations on my TT. the first was my 2.75" neuspeed. perfect sound level, NO boom on decel. car wouldn't boost over 22psi. as soon as we removed the system, 26psi was had........only change being a 3" full system. i then had a Magnaflow system made w/ 3" in/out everywhere. flowed, but too loud. added a small 4" resonator= little quieter but boom on decel. replaced w/ 5" resonator = quieter, MORE boom. drove this until couldn't take it anymore. then tried another 3" system that was quieter still but unfortunately lost 2psi . Car was about 5% quiter but felt like it lost 10% power. laggy, no top end....but smooth.

then came my idea of two parallel exhaust pipes that were 2.25" each. the idea of ridding the car of the 3" diameter might cut down on the boom but being 2 of them equalled an effective 3.33" pipe. Billy Boat Exhaust decided the idea had to be tested. they also made their very cool Y design back section that is perfectly straight thru. in testing the new set up, i left the current BIG resonated 3" front of the exhaust and ONLY replaced the axle back portion with their Y design. It instantly woke the car up, was actually quieter, and gained me 1 psi back. so the next was to pop the new front section of exhaust in. i now gained my 2nd psi and am back to 26 psi. the car spools VERY fast and pulls to 26psi W/O any prob. there is less decel boom......it's not gone.......but definitely better. the new mid pipe is alittle louder overall but the speed at which it spools, holds boost, and lacks boom........is perfect!! here is a summary of my last couple weeks:

3" full system w/ traditional but high flow muffler design = 24 psi and slow

3" front section w/ big resonator on and new Y back section = 25 psi, fast and really quiet.....but w/ boom

2 x 2.25" front section and new Y back section = effortless 26 psi, very fast, crackly decel, pretty quiet, less boom.

Mike and Billy at B&B are awesome!

 

Now how the hell do I post pics on this new format?

 

Click on the icon that looks like this..

Oh and BTW.. YSATI... :-)

 

I don't know where the hell you find that img link. if this works, i had to copy your link and manipulate. if it does not work, i'm even more lost.

 

Don't you see any icons just above the box that you type a message into?

If you don't you'll need to go into your user settings (click on User CP in the main menu). Click on "Edit Options" in the menu on the left. Scroll all the way down to the bottom and change Message Editor Interface to use "Enhanced Interface "Full WYSIWYG Editing". You should see all the options at that point.

 

BTW, nice looking exhaust. Your picture did work.

 

the Y looks exactly like my 3" apr exhaust. Nice

 

wow looks great!

 

so is this now going to be a billy boat exhaust? where can you get the Y section in the rear from?

 

Must have been a lot of money (unless it's growing on a nearby tree).
