The HKS Mild Steel DP is made to fit RHD cars like those found in Japan. It has a tight bend in the neck just after the turbo manifold to accomodate for the RHD steering column. I would by a DP that does not have this bend.

 

A warning about the Megan Racing downpipe found on ebay: the fitment issues aren't quite worth the $100 savings to most people. Time is money, and I'd rather have not spent an extra 2-4 hours under my car with a dremel, trying to make the holes line up, only to have an exhaust leak caused by the downpipe-to-cat flange being at the wrong angle. It's off by at least two or three degrees, enough to make a ~3/16" gap at the top even when tightened down snug.

Maybe pettit's downpipe?

but like i said before, anything is better than the stock pre-cat. I suggest losing it quick.

 

I like my HKS one. Easy to install, good quality and replacing the O2 sensor is easy.

 

i had one custom made, just one smooth bend to a mid-pipe w/resonator, all 3"ID of course..

 

Also consider the M2. It was a perfect, bolt on fit. Didn't have to remove the studs or have any fitment issues at all.

 

try this place
www.city-speed.com
downpipe and midpipe for 125 shipped.
ohh and they fit without issues.I know.

 

I have an HKS on my 89 TII, and its great. The pettit one however is very easy to install on the FD, I would go with that

 

Try the gothamracing.com downpipe...I didn't have any fitament problems, and it was cheap! all stainless too!

LOL... you posted the exact same thing 3 years ago...


edit: oops!... maybe it wasn't you

 

I like the Pettit one the most. Perfect fit and stainless. The HKS isn't a good one to buy if you want the best flow, however if you want to buy a name...

I say Pettit or M2.

 

I've got the Bonez dp from rx7.com and I can't see it sliding on any more easily than that. No fitment issues. I stuck with the mild steel pipe. Stainless is nice but the regular one is still going to outlive the car.

 

I have a Pettit for sale on the 3rd gen parts forum (pics) for 200$ They are 300$ new. Here's the thread https://www.rx7club.com/showthread.php?t=355238

I had a ATR downpipe. It's a knock off of the original ASP design. Worked and fit good, I used shorter hex studs so it was easier put on and remove. I would look into getting ceramic coated which ever one you choose.

 

I'd go with the ebay dp/mp $100 combo...I mean come on, how hard is it to stick a drill in the existing holes and enlarge them.

 

got my ebay/gotham/megan racing DP,MP. Fits great. Stainless. Why spend the extra cash for the same thing?

 

Some people have had some headaches with the knockoffs...

 

Yes indeed. I got a In house brand from a well known and reputable shop and it didn't bolt up to the cat properly. Sent it back and got it exchanged for a HKS. Bolted up perfectly.

Stick with the tried and trued for this situation. That's just my opinion.

 

HKS is BEST

 

I got my downpipe from SR Motorsports. No fitment problems although I did have to replaces the manifold studs with the supplied bolts. Since my studs came off easily it was no problem for me but I hear it can suck if you happend to have problems removing the stock studs.
