Well the GS pipe is stainless steel so you wouldn't have to worry about it rusting out. The JT is aluminized steel which will eventually rust (how soon I don't know). From a JT downpipe that I've seen for a ng900/og9-3 in comparison to Nick's I'd take Nick's any day of the week. It smoother in terms of the flow pattern.

 

As far as longevity is concerned I wouldn't be too worried about the JT. The one on my 9000 is 6 years old. I think you'll also be fine with a catco or something similar (about $40-60 from Summit or Jegs).

 

mike, you only drive your 9000 in the summer with temperatures in the 90's, no rain and relative humidity in the 50's. not a fair comparison.

chris, if you are plan on keeping your 9-5 for 2 or more years.....go the stainless route. initial cost a bit tough to swallow but worth it in the long run. you will be glad you did.

I learned the hard way...twice...but i'm polish and sometimes it takes a bit to sink in.

I have the JT DP in my 2000 have been running it for 4 yrs now its it rusty but the DP burns so hot that it really never get caked or flaky at all, the rest of my 3" exhasut is steel but it looks a little worse and have only been running it for 3 years... but not rusted through.

If you are think cash is an issue now but might not be in 4 or so years than I would say get the JT and if you still have and love the car in 4 year and have more cahs then buy SS.

 

Don't cheap out on the cat! It will be the main bottleneck of your system.

For example, Nick had issues with the Speedparts cats:

http://www.trolltuner.com/archives/2006/02/backpressure_pt.html

A good 3" Magnaflow race cat shouldn't cost too much.

 

I think I've decided on the full JT system.

As beautiful as the SS GS v2 Downpipe is, my exhaust is pretty ratty and I'm on a budget.


So now the question is one muffler or two... hmmmmm.

Anyone have experience with these?

 

I wish I would have waited and gotten the full JT exhaust instead of only the BSR cat-back for over $400...

 

I don't know.... I had the JT on my 9K and it was cool. But now after having the BSR on my 9-5 I think I prefer that. Just enough to know its there and just enough to forget it. As far as quality I consider them equal.

 

i would go for two, you can always cut one out if it isn't loud enough

 

Good call!

I plan on keeping the car for....... as long as possible, another 5-8 years
seems reasonable. Hmmmmmmmmm, something to think about! Was that 2 years of driving the car through the winter though?

wow thats ugly.

stainless does look good too........

$tainless $teel

Hey Dave...I actually put three winters on that exhaust. Two on my old 9000, one on the Aero

you drove the aero in the winter?!?!

i think the world is going to implode.

no way mike drove his newer 9000 in the winter. he is absolutely lying to us. his car looks better now than it did when it was new...if that's possible.

Haha, I don't believe this either!

I went for the JT full 3 inch with two mufflers and like the way it sounds. It is louder but not to the point of being obnoxious. I bought the Catco converter from Summit. I did have an issue with it, it started to rattle internally after about a year. I was able to return it to Summit and they sent me a new one for free. No issues since then. I did have a hose pop off and didn't realize it for a while, not sure if that would have damaged the converter.

My exhaust is now 3 years old and in fine shape, but I only drive the car in the summer.

What hose popped off?

Yeah, I've talked to a few people that have been running JT systems for 5-6+ years and the pipes still look good. I also keep my Aero off the road during the winter, so I'm sure that will help!

I would go for the 3" JT system with one muffler. I like louder exhausts.

Also, you need a 3" high flow cat to run with the 3" JT exhaust, not a factory cat.

I already found a Magnaflow 3" cat (13" total length, 6" width) on ebay for $70 shipped!

As for the rusting issue... A few coats high temp paint???

 

wow thats ugly.

Nope, not a lie. First year I owned it (2005) I drove it that winter.

I was at the pay & spray once a week.

Yeah paint saves things, or at least prolongs the process of rusting.

 

hmmmm....

I may just do that then!

 

Agreed on the paint.

Plus your exhaust system will still weigh less vs. SS.

It's aluminized steel, as in aluminum coating on steel, not straight aluminum. Sorry, no weight savings to be had. You don't want an aluminum exhaust, it has a very real chance of melting.

 

Why not just an Open downpipe it works for mike d... but were in maine and nieghbors actually care about noise here. exaust fines are 137.00 too
JP

 

I wonder how a committee decided on $137.00 instead of $130.

 

Maine is arbitrary like that.

 

i got 2 of them...
one was for inadequite exaust, 137.00
and the other was for excesive noise 137.00
and failure to produce proof of insurance
all in the same ticket.

I think it was just a bad day, my car isnt even loud. tested at 105 decibels at 3800 RPM, the limit is 95 decibels at 3/4 of the RPM where your car makes peak hp.

mine has a low tone so it reads higher with the decibels, if you have a high pitched fart can you can get lower numbers

1. 105 is pretty loud, that's about where hearing protection becomes a really good idea.
2. low sounds travel far. I can hear subaru, V8, and diesel rumbles from the major roads 2-3 miles away when all is quiet in my house.

 

Why can't that JT kit be installed the '04- '05 Aeros?

 

The bumper probably.

 

Spray it with high temp paint. A buddy of mine did it for his S4 and it looks about the same as it did 4years ago. It is his daily driver/racer so.. Oh yeah and he lives on the gulfcoast of florida.

Think this had something to do with it?

 

Usually exhaust dies from the inside out. Most of the time the rot starts at the seams of the muffler, and once you see it, its already 10x worse on the inside. Paint won't do a lot in that situation.

 

+1.....the condensation from the exhaust just sits in there and collects at those seams.

 

i'd really suggest painting it with some POR-20 i did my JT exhaust with it, and the single muffler no cat is pretty loud when WOT comes around, but i like it and the cops dont seem to mind. if you're looking for something to pull into a quiet neighborhood with at night- stick with the 2 mufflers.

and unless you have emissions inspections- leave the meow meow off.
if you need it, I have a stainless 3" magnaflow cat that was on my car for about a year, its yours for 50+shipping

 

usually it doesn't have to "hurt" to damage your hearing.

my dad used to drive a large dump truck at a mine between summers in college. he is now deaf in his left ear from the constant "drown" of the truck.


also, a hammer pounding nails is one of the most damaging sounds for your ears.

 

my hearings prolly screwed anyway, the army took care of that. come to think of it i hear ringing alot? wow maybe i need help
