Why run twins if new singles are so good?
Twins
Watch out for this!!!!!!!!
Most twins have two problems.
1) They just are not going to spool like a small or mid size single (60-64mm). That wasn't a big deal to me since if I really wanted them to be there for me on a launch I would boost brake. That's a little hard to do from a stop light when you live in a large Metro area,... the smoke,.... tire burning,... ...issed off people behind you with cell phones taking your license number down and call the locals on you. The mid and high range is just freakin' awesome.
2) You need to ck out in the best manner possible for slag left from welding in your cold pipes. Guess where that will go?? If you're lucky it's just a turbo but obviously it can get a lot worse if it goes on through your intercooler and engine. No one ever talks about that cold piping but it is a concern YOU should have if you run twins. Stick something flexible up in the pipe and feel for slag ridges and then try to get any hanging pieces off by the best means possible,... maybe a flexible Dremel tool or whatever it takes as to let it go is like playing Russian Roulet.
All twins and welders are NOT created equal.

RC's Setup
However he made huge power with the original Artic Air setup. I suppose it just wasn't enough air for the way he's currently equipped.
Only one I personally would steer away from is shied and thats just cause I felt there plumbing that I saw on there dispay unit was very poor. Grind and hack marks, choppy paint, and cut into the radius with heavy schedule carbon pipe fittings,yikes. No offense to their fans but if its your display ya know make it look GOOD. I also hear that Artic Air is the cheapest way to do twins but that has been debated before. My .02
IMO why would you want to tow heavy with 500+hp anyway? That is so much extra stress on parts it is rediculous, your EGT's may stay sane 9with twins) but what about tranny and diff temp? They could skyrocket, also your drivetrain takes a royal thrashing, u-joints and yokes get stressed badly... I think on the 3rd gen's they can run large singles and still have good manners on the street when turned up and then tow well with the power at a lower level... My .02
I TIG'd mine and I can assure you there was no slag or rough welds hanging around. Powder coating is very thin compared to spray so any flaws will be very visible. Most of the twins makers I've seen wouldn't last a day in the custom motorcycle market as far as fit and finish is concerned but they do in fact make nice products. Make sure the builder is willing to stand behind their setup....if it doesn't work they're on the hook. Some of these turbo builders figure cause its on a truck it can be rough and tumble fit and finish. ks
