So on my S70 T5, I've got an EST DP and the IPD cat back stainless steel exhaust. I recently bought a Magnaflow muffler with tip for the car. Here is the problem, the IPD exhaust pipes are still in fantastic shape, but I want to remove the first muffler and just run the muffler at the end of the car. I checked a few shops around where I live, and no one does stainless steel pipe work (WTF).

For everyone else on here who is getting custom exhaust work done, are you using stainless steel pipes or just regular steel pipe? Since the IPD pipe is still in good shape I really hate to lose the stainless pipe. I guess I could just order a piece of stainless pipe long enough to fill the hole of the one muffler, but then need to find a shop that can work on stainless steel pipe.

What is everyone else doing?

I also had trouble finding a muffler place to weld stainless, try a welding shop instead. What you want done is really easy for a pro welder, so the place doesn't need to have anything to do with cars.

Where are you located?

I bet there's someone keep asking around. I found a shop that does stainless and works on Airplaines so you never know.

another option= find someone who can bend it and flare it for you then put it together with clamps.

Might want to try some hot rod shops.

why are you replacing the TME muffler, its a very nice piece

[leroystew]

I'm located in NW Indiana.

I'm impressed with the sound of the TME muffler at the end of the pipe so far (the EST DP really improved the sound 1000% compared to the stock POS), however, I want to get rid of the suitcase muffler in the middle of pipe closer to the CAT. Hoping the sound will get even better.

Alternatively, I also want to hear how the car sounds with the Magnaflow muffler bolted in place, compare the sound of the 2 mufflers, and keep the one I like best.

I have a 3 in. DP > 3 in. high flow cat > IPD/TME catback....minus the resonator (first muffler) which I had straight piped and it sounds effing mean. You will get a little drone cruising on the highway but the sound is incredible. It sounds so pissed off when you romp on the gas.

I was looking at the Borla exhaust systems and parts, and I guess I could buy a piece of stainless straight pipe and the band clamps and do it that way. My mechanic friend has a MIG welder for the welding needs, so perhaps its as easy as that. I'm really antsy to get that suitcase muffler off and hear the car.

you could always ditch the cat , it will make for a really aggressive sound , use clamps after you remove it tho , that way you can bolt the cat back into place for emmisions testing

[dublin14]

Find a fab shop. If there of any use will have a someone that can weld SS!

[leroystew]

My mechanic friend who rebuilt my motor should be able to weld the SS for me. He did welding on the EST DP for the AFR bung and the airpump bung, and based on what I saw this past Saturday, his MIG welder should be able to do the SS welding.

I love the sound of the TME muffler now, can't wait to hear it with out the suitcase. And then I have the Magnaflow muffler also to hear. The EST DP came with a race cat, and I think I am going leave the CAT in place since Indiana requires emission testing and how much am I really going to gain by removing the CAT anyways. Don't feel like messing with clamping it on and off.

Simply removing the cat isn't going to make the car sound that much better, all the while spewing more pollution into the air

You can certainly MIG stainless (make sure he's using stainless wire,) it just won't be as pretty as if someone TIG'd it for you. A lot of truck body places can weld stainless, might look into that.

I'm not sure I really need much welding for what I want to do. If I remove the suitcase muffler, and put a piece of SS pipe in its place with 2 band clamps I would think that would do the trick. As for the tipped muffler, if I replace the TME with the Magnaflow, the Magnaflow has a 3" inlet so I need a transition piece from 2.5" to 3" to fit the Magnaflow muffler.

autozone for <$5 ... or if you want a nicer look and to have the exhaust resonate a bit better you can get a 2.5" pipe flared to 3"

i liked the sound difference after removing my cat , not to mention faster spool time , as for pollution , thats the least of my concerns , if its even on the list at all ahhahaha

did you add 2 hp by doing that? you can get the same performance results by taking the spare tire out of your trunk, probably better results because there would be less weight behind your rear axle

just get a 3 inch high flow cat

hahaha , changed my hp and torque curve too

the cat is 30-40lbs , so that right there is equal to the weight of the spare tire , and then you have a less restrictive exhaust , and therefor faster spool times ect ect ect

but alot of it is preference , not everyone want the added noise ... and pollution ...

race cats are worth the money if you have to worry about emmisions , i dont , and sense i dont worry about noise i run a straightpipe ... but we're getting off topic and starting to threadjack hahahahaha

Cat is not 30-40 pounds... It wasn't the last time you mentioned that and still isn't

For the original poster, MIGing stainless is just fine. I do it with a crappy flux core welder and the welds are very durable... Most flanges are sold in stainless, most mandrel bends I work with are mild steel, I just welded the downpipe for my 850 the other day, welded some mild steel pipe to the rest of the SS downpipe, then on the other side welded a stainless flange to it. It works just fine...
