Tims,
I still dont like the bellmouth.
Why can't you do a siamese pipe setup? Stick a 1-1/4 pipe on the side of a 2-1/4 pipe (i think that's the outlet) and then merge them into a 3 inch in the downpipe after a foot or so. you want ABSURD flow, I bet that tickles paul's prostate about 100 rpm sooner.

Bellmouths worked well for me, paul, artie, and the subie crowd tends to see better results with them than with the divorced WG setups. Plus there's still people giving BEGI grief over the flapper blocking the WG tube which even though it isn't true you still have to convince the buyer otherwise.
I don't know personally what would be better performance wise. Bellmouths are a little easier & cheaper than divorced...IF (big IF) there is a positive difference to divorced WG's, is the few extra hp worth the much extra $?
If there was demand I could do one. Actually that first bend would probably be easier. That downpipe I made for evan K does look sexy and it was surprisingly easy to do Maybe it's been too long to remember otherwise. Divorced WG on the "standard" Absurdflow manifold would be pretty easy to do...hmmm

Thanks, and I hope Steph/BEGI doesn't have a problem. I doubt they will, I'm small fries. Or maybe she won't notice this thread. I'm just some guy with some cheapass Harbor Freight tools and a really nice welder (seriously if you guys saw what I use to make these manifolds you all would be doing it). I don't want to mess up my dad's business relationship with them either. I don't have anything to do with Shore Motorsports other than using their power to run my welder and doing "fab work" under their name after my real job if they need the help. I figure now that I have a house I can do this stuff on my time and start to seperate from Shore Motorsports and into the Absurdflow name.
BEGI makes nice stuff at great prices and are very eager to please. We are very lucky to have a vendor like that in our community.

And the 3" outlet is not always needed. All NB downpipes that end in 2.75" will bolt up to a 3" exhaust making the 3" outlet a moot point. The only time a 3" outlet would be needed is on a NA car. Then it locks you into a 3" exhaust becuse it will not bolt up to a stock size or aftermarket size exhaust.

Thank you Steph, that means a lot to me.
I do not want to be misleading. Thank you for the clarifiation.
Why does only the MSM get a cat? What if I want to purchase a 3" metal cat for my '94 1.8 to go with my stainless SGDP? Is the price not $240 for a 3" metal cat for a '94 1.8?
ONLY the MSM gets a CAT. So your price listing is slightly mis-leading.

Oh hell yeah on that pipe 2.25 for ~2", smooth Burns transitions to 2.5" for a little then another to 3" right before the WG blends. Yummy.

The point here Stephanie is if you want to get a better flowing DOWNPIPE AND CAT for your turbo Miata, Tim's setup comes out cheaper than buying your downpipe and a high flow cat from you. What's the point of going with a better flowing downpipe to force it throw a restrictive factory cat?
Tim's setup reaches and bolts up to 90-97 factory and aftermarket catbacks.

im glad i have the shittest wastegate outlet design possible. if my exhaust flowed any better i wouldn't be able control all the creep. i still make 11psi on a 6psi wastegate.
i have a 2.25" outlet, no bellmouth.

So with my 7psi actuator (that is most likely blowing open from the inside) I should make over 200ft-lbs of torque at 3050rpm instead of 3150 if I get a separated gas design? Sweet. Tim, get on it.

it's the same reason you dont want to (ahem scott) run a gutted cat instead of a straight pipe.
