When the new turbo setup is done I'll be running around 3" piping likely with a high flow cat and a 3" Magnaflow with an electric cutout for the racing stuff.

Depending on how it sounds with all of the new stuff I may change some stuff around. If the changes make it louder at my regular cruising RPM I'll probably go to a different muffler setup and just rely on the cutout for going all out.

BTW...i know i need to finish exhaust and get a high-flow cat...just too lazy i guess, lol. but hey - its on my list!!

Im running an ebay muffler, 2.5" Intake 3.5" Tip.

Also had custom 2.5" piping and de-cat pipe installed.

Car growls like crazy, it sounds like a WRX with an aftermarket exhaust.

installed some pacesetter header, but they sucked beyond belief.

Looking to get a y-pipe, who makes a good one for a third gen?!

Car sounds great though, i love its sound.

A magnaflow muffler w/ custom catback is a whole lot cheaper than the SP2(at least from back in the day when I did the exhaust. I dont know how much it runs for now.
I currently have a 5x8 oval body Magnaflow street series muffler (89.00 on ebay*new*), two resonators(35.00 ebay*new*) and 2.25 tubing straight to the test pipe (150.00).

I just mimicked the SP2's design, thats why I have two resonators, which are located on the straight tubing before it reaches the muffler.

My exhaust set-up:
Aside from what I mentioned above,
Custom enterprise test pipe
OBX headers

4.08 VLSD, NICO 8-way ECU, full exhaust with custom headers,
Tokico Blues with Eibach springs, Stillen FSTB, 20mm RSB, 255 rear rubber.

I _had_ a WarpSpeed y-pipe, but it was removed due to banging. Crappy design and horrible customer service. Not recommended. For the rest, I have a factory cat and muffler, but a WarpSpeed B-pipe with resonator. So far, the B-pipe has been fine except for the installation when it was determined to be 6" to short for the maxima and had to be extended. Again, shoddy work on their part.

Actually frequent removal probably helps the damned things from getting rusted on.

(and $500 for o2 sensors? wtf? genuine Nissan replacements are $90-125, labor is about 5 minutes' worth...)

If my car is automatic and I don't plan on racing it, is it even worth adding a cat-back to it? I know the Y-pipe is supposed to give you the best bang for its buck as far as HP gains, which is why I purchased it, but I'm only looking for an increase in HP for personal satisfaction while doing my daily driving.

Also, does anyone know how long the battery must remain disconnected in order for the ECU to be reset/reprogrammed? OR is there a faster way to accomplish this?

All the parts work as a system. You'll see 10-12whp and 10-12/wtq with a y-pipe alone, but adding a highflow cat and an exhaust probably won't do much more PEAK hp/tq... you might see 15-20whp and 15-20wtq total. However, the gain at each point on the RPM curve hopefully will be higher than with just the biggest power adder (the y-pipe) installed.

So if you've already got a y-pipe installed, the high-flow cat doesn't really add any power to an NA car, the catback is probably only a few whp/wtq more...

I've now read some posts about it needing an "adaptive learning" period of time. Therefore, does my ECU even need to be reset?

Thanks for all your insight!

I did. The best price I could get was thru Gary.

I have been working 75+ hours a week. I simply do not have time or energy for that.
