Re: Exhuast questions

First, aluminum is not to be used on automotive exhaust. I also would not advise on powdercoating.

I have used VHT Flameproof with decent results. The key is to cure it properly, and to put on an even coat. I still need to finish my Y pipe.

Re: Exhuast questions

Cool thanks for the responses...

I wont be getting the Aluminum exhaust, and will stick with Stainless.

I have a Borla now, and its Stainless but it has been rust spots on it too. I will give the powdercoater a ring and see what he'll charge. Same with Jet Hot.

It doesnt have to be all black, i just dont want a big chrome tip out the back.

So suggestiong on Gibson vs. MBRP? What what about the header length question? Will I have to modify the exhaust when I put in headers or will it bolt up?

Re: Exhuast questions

409 Stainless will surface rust, 304 Stainless is what you want...non-magnetic and will not rust ever just make sure they weld it with 304 also.

Here are some pics of the AR headers.





If you really plan on doing the headers just get a dual inlet muffler and block one side until you get the headers. The AR Headers are 3" so make sure the rest is also 3". I know Gibson is 3", not sure on the others.

Re: Exhuast questions

How many cats are on the exchaust?

If I were to add headers, would I just go from the headers, to a y pipe, to cat, to muffler?

Or would it be header, to 2 seperate cats, to Y pipe to muffler?

I dont think i want the gibson exhaust, its aluminum except for the muffler and exhaust tip... So I think I am going with the MBRP 3in 304 exhaust...

And down the road when I want headers, ill just have them put it up to the stock exhaust if need be

You must be confused....ALUMINIZED is NOT ALUMINUM.......

It's steel that has been coated to prevent rusting. It works well enough, until that coating comes off. I ran a Aluminized magnaflow for 2 years in NJ, saw mud, snow, etc etc etc....it was relatively clean when I sold it to a buddy of mine, who is still using it on his YJ.

Re: Exhuast questions

Powder must cure at around 400 degrees so it's not as delicate as you think. If you want to just powdercoat your tip, that should be fine. That's what I'm doing, I might powdercoat it the same color as my wheels. If you want to coat a header, you should use a high-temp coating.

NIC makes some nice powder and ceramic coatings, they're also have great customer service: http://www.nicindustries.com/index.php

Re: Exhuast questions

I am aware that powdercoating is extremely durable, I am not getting headers, but when I do, I will most likely get them jet hot coated. My question was if it was possible to powdercoat the aluminum exhaust so it wouldnt rust, but since I am getting the 304, I wont need to... I am going to paint the tip black though.

I am placing the order today for the MBRP exhaust... 304 stainless all the way through. And a BBK 85mm Throttle body.

I should have a better idea about the headers after I remove the borla and put this one in. Should sound pretty good

Your Magnaflow catback system is rusted? I had the Magnaflow catback previously installed on my WK for under a year, which it saw last winter. It appeared "rusted" at the welds and some areas of the tail pipe, so i scraped it with a wire brush and it looked almost new again. It maybe just surface oxidation.

And I meant Aluminumized, and not just Aluminum for the pipes. But for the price, stainless steel is the way to go. Even with powder coating there might be a chance of something not coated properly and the coating chipping then the pipes rusting, I wouldnt just because of the cost.
