Is there a difference between a name brand DP and non name brand DP's?

Would it be a bad decision to get something like

or spend more money for a name brand one?

thanks

big name companies got to be big name companies by introducing quality products

Spend the little extra cash...

I hose is a hose...

but people have complained about the flanges on the cheap peices... they don't seem to line up well sometimes... I think it is hit or miss...

Buying the best of everything gets expensive... sometimes a cheap eBay peice can free up money to use elsewhere... someplace where you wouldn't want to risk using a cheap part

Some people have reported fitment problems with the flanges on some of the 'cheap' pipes. Others have not had a problem. The worse case scenario is that you take the car to an exhaust shop who does some grinding on the flange for a better fit.

Having said that, I've been using the Bonez downpipes (www.rx7.com) and generally recommend them. They are more expensive but the fit is good.

Get the best of both worlds - buy a used name-brand downpipe . I bought a Bonez one some time back for $40 on Ebay - NO ONE ELSE bid on it because it was rusty. Had it ceramic coated, looks like a million bucks.

That said, the cheap Ebay downpipes are pot luck. I had one on my car that fit OK, but the angle of the rear flange was a little off, making for a very small exhaust leak. For the exhaust system to be nice and tight, each flange needs to line up with the other perfectly.

I'd just keep an eye out for a good used one - they come up pretty frequently here on the forum and on Ebay.

To show how hit or miss they are, I bought a used RB intake duct, K&N filter, & metal intake pipes from a local RX7 owner. He told me they were ebay pipes & the one didn't fit, I was aware of it. So the one fit great... & the other was WAY off... there was NO way it would go on the car... it was a bad, cheap eBay part.

I also have an eBay DP & it fits fine...

I had the same results as Dale with my DP, rear flange didn't meet up and it created an exhaust leak. I didn't buy the DP from Ebay either (won't mention company publicly). I fixed the problem, but quality and reputation does make a difference.

The Bonez pipe is very well made. Roll the dice on ebay stuff. Make sure you get stainless steel.

I had an HKS on my last car I loved it. But it is true that because it is made for JDM cars with the crease it does restric flow a bit.

On a related question anyone ever heard of the Trust downpipe? It is supposedly 80mm where are the HKS is 75mm.

Thanks,

Someone awhile ago posted a Greddy DP for sale in the FS section. I don't think anyone (including the seller) could verify whether or not it was truly a Greddy pipe. You might try seaching that section and see if you can find that post.

need a downpipe? LOL

I got a "petit" downpipe... But it was much too loud for my taste. I just had it replaced with a high flow magnaflow cat and the sound is a lot better IMHO.

Depending on where you go some "bolt-ons" aren't really "bolt-ons". My bolt-on cat was too long...

The downpipe I am talking about is actually listed on the TRUST site in Japan. I saw the product on rhdjapan.com.

http://www.trust-power.com/01exhaust/tr_frontpipe.html

It says:

"TR front pipe (competition exclusive use) "

"It is the competition private front pipe which can expect the substantial power rise of the extent where re-setting of burning pitch becomes necessary. Because as for one for FD3S boost pressure rises substantially, re-setting of the computer is needed. GC8 because it becomes with the catalyst less, shows power at the time of limited travelling with closed course."

"Rx-7/E-FD3S/99.11~02.8/13B-REW/80mm/28350"

Right now I am getting a downpipe locally for cheap. But if it doesn't fit well I think this means if I want to try this product I will have to be the guinea pig.
