Simple poll... my cats clogged and gutted long before I bought the car because the PO blocked off the hose from the air pump to the AFM... (WTF... I don't know) so now I am finally going to buy a downpipe/midpipe combo. The cat back is currently stock to the best of my knowledge. I'll replace it soon but I am not excited about the hollowed cats on the car so... which do you recommend?

 

You left off some companies, and if they have a custom system.

 

Yo,

Racing Beat's stuff is top drawer. You won't be dissappointed and it lasts forever.

KS
1989 GTUs "Shiny stainless!"

 

i went with racing beat downpipe and custom midpipe. great build quality in every part

 

The CorkSport stuff is 3" / stainless. That's what I might go with next when i get ready to turn up my boost.

 

well I can only put 4 options into a poll and I picked the names I've been looking at and see most often.

 

corksport doesn't have any dp or mp in stock. another reason i went with RB

 

the people have spoken (a few people anyway) and it looks like racing beat is the way to go.

thats why i've decided to order the thunderfabrications pipe.

:-)

I know I know... why the poll if I'm going against it? Well, at least now I know where the quality is for sure, and what works.

Now I want to give other companies a chance to prove their quality. Thunderfabrications.com offers a 3" mandrel bent dp/mp single piece unit for $175 shipped. The price can't be beat. The downfall is I don't have the option to add on a presilencer or catalytic converter later. I shouldn't have to as there are no emissions here and cars older than 1990 are not required to have cats by law. So I'm giving the small shop a chance and I'll keep you posted. Thanks for posting your opinions, I do value them even if I'm not going with them.

 

RB downpipe and presliencer are hard to get right now. Mazdatrix are on back order for over a month. Racing Beat said they were getting a shipment in but that was 2 fridays ago. I checked today,they haven't shipped them out yet. Anyone know where I can get one? Thanks

 

Sure you do have some choices. If you live near a shop that will do custom work, you could get them to hack the Thunderfab into 2 pieces and add flanges. The part cut out could match a length of a cheap cat (for passing emissions or inspection). Simple and cheap.

 

Custom made 3inch downpipe and midpipe all in one piece with manderal bends, half the price of 'off the shelf' ****

 

I got the ATR Stainless steal Downpipe and Midpipe for 380 bucks. I put them in myself so I can say fitment was very good. Very thick walled Stainless with very nice welds. For the price I dont think you can beat them.

 

$175 beats it... I don't think the quality would be 100% better. I haven't seen the TF pipes up close and personal but they are mandel bent, have thick flanges and a sotck o2 sensor mount.

Locally there isn't much for shops that will do custom work and NO shops that can do mandrel bending so I don't see the custom setup happening.

It's possible I find a shop to cut the TF downpipe and weld a flange to it if I need to put a cat on... but having a shop make a complete setup around here isn't going to happen.

I've gone into a couple of hardware stores looking for the parts to make the 3" TID mod. Can't find anything... 2.5" to 3" rubber hose doesn't exist locally. I'm going to have to order something. Frustrating.

 

My bad man. Oh, I forgot to say I went with the RB down/midpipe. I am very happy with them, best modification ever.

 

Me too.

 

Hmmm... you guys put up a hard argument for RB. I'm really glad to know they make some quality goods. I'm still gonna go with TF and hope for the best. It's about $110 difference in price Canadian... and the money isn't really an issue. I want to know who else makes quality parts and help support them. If they suck you'll hear about it and if it rocks... you'll also hear about it.

I hope this poll keeps going for a while. I find this very useful information.

 

I was going to buy an RX7Fashion one first. Then the guy was being bitchy and saying he could only do it if I got a group buy going. So I looked at the TF one. I'd never heard of them before, so I just went ahead and got the RB one, since almost all of my FB is running RB stuff, and I know they make good ****.

 

the thunderfab pupe is great, very nice, good construction and it sounds really good and really good fitment

 

pupe...

Racing beat all the way (yes i know i have pacesetter, but they're cheap and get the job done )

 

yes , racing beat is the way to go, seems like a whole new car with the 3in. dp and pre

 

anything that is 3" or bigger that wont rust.. SS... thats the way to go

 

The votes speak for themselves. I have a 3" RB downpipe and a High flow cat. The pipe is amazing construction quality, and even has an extra plug in it, which Ill be putting a EGT probe in. My only grip is mine isnt SS, but I had it Jet-Hot Coated grey, so it looks alright. Maybe ill get a SS RB pipe at a later point in time.

The DP came on my car, and I wouldnt want to know what it was like without it.

 

Can you bolt on a 3" DP to a stock header?
What size is the stock header?

Im going RB dp/pre silencer with corksport single catback

91 na
thx

 

13bforlife if you have an NA you probably dont want a DP that big of a diameter. For turbo 3" is fine, but for NA you will only want 2.5"

 

I just put the TF one on my car today. Putting it on was a breeze but I had the hardest time getting the stock **** off.
