Green9kAERO I Prefer MikeD's Method, because it usually works out nicely. You buy Mandrel Bends, Muffler, Pipe, and a Mig Welder..... After the Exhaust is done you get a free welder out of the deal

mike d i would assume a full exhaust comes with atleast one 02 bung,, if not im sure every person who ever purchased on would complain very quickly..

snowsaab Just realized this is the 9-5 section (im smart). Oh well, it still works haha.

Your rear O2 could be turned off via T7 Suite...but I'm not sure how the T7 works with the two cats.
Yeah i was talking about the o2 stuff with Logan, it sounds like everything will work out ok.
We all know how clean i keep my cars, being this is going on a vert ill want to keep as much salt off the car, especially the top, as i can, so rusting SHOULDNT be an issue....right away. Oh and im going catless, and doing the 2 muffler set-up. I figure without the cat, would probably be too annoying with the 1 muffler system.

i work under the logic of get the single muffler, and add one in if its to loud!

as far as quality is concerned,, ive always DIYed the downpipe, then seen a custom exhaust shop for the rest.
if i was truly worried about quality, i would coat the system with some cheap high temp (typically gas grill) spray paint, it seams to add 2-4 years of life to the system..
T7 programming wont be an issue.

Im probably going to give it a coat of high-temp paint for good measure.

Although, one question i do have, the JT system does NOT come with the o2 bungs does it? Id have to create my own?

Cark The Christmas season seems to be going well for me, lots of overtime and a bonus on the way. I think I'm going to treat myself to a GS Downpipe and finally get the car retuned. If I could get just the JT DP I probably would, but I have no interest in the entire JT exhaust system. Aside from it being a tad on the pricey side, I've heard nothing but great things about the GS pipe. I'm really looking forward to it.

snowsaab glad i found this thread as ive been thinking about a full JT exhaust.

midwest peeps chime in....will i be alright putting this on a DD that i keep pretty clean during the winter?

being in WI i technically dont need a cat...BUT....will i need it for my o2 sensors? (i have a 01 vert SE)

My exhaust after 100,000K miles and 7 winters in NH rotted from the outside in due to water, salt and that lovely crap that exists on roads in NH.

High temp paint, if done correctly will keep an exhaust from rotting on the outside. Then you will have to worry about rot coming from the inside out.

Aerolike9 i got mine installed and its rubbing on a bolt under the car...

There's 1-3 week ship time from Sweden... so now I'm playing the waiting game. The car's inspection runs out the end of this month so I am probably stuck taking my Camry to the next NESA meeting since I doubt I'll have the exhaust on the car+inspected/registered by the 4th.

1-3 weeks, my ass
Did you get yours installed, yet?

I put pictures/video of mine up.

Aerolike9 did you buy your JT with the Cat or the one with out the cat on GS ?

I've never seen my exhausts rot from the inside out... my mufflers are always shiny on the inside after the shells have rusted out externally.

Chris, let me know how it works out? I'm buying mine next month, I just don't want to get a CEL once I put it on no matter what I did on my 9000 I got a check engine light
